It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.

The NVIDIA® Jetson Orin Nano™ Developer Kit is a perfect kit to start your journey of local generative AI evaluation and development.

+

This guide explains the complete flow from opening the box, updating the firmware if needed, flashing the latest JetPack 6.0 GA image on SD card, and the initial software setup, so that you will be ready for tutorials listed on this site and other AI projects.

+

Check your inventory

+

Following item is needed or highly desired to set up your Jetson Orin Nano Developer Kit.
+If you don't have them in your inventory, you want to arrange them and come back to this guide once they are available.

+
+

What you find in the box

+

+

Jetson Orin Nano Developer Kit

+

The Jetson Orin Nano Developer Kit consists of Jetson Orin Nano module (enlarged SO-DIMM form factor), and the reference carrier board.

+

It is designed to use a microSD card as the primary storage, thus the module (that has a big black heat sink with a fan) has a microSD card slot at the bottom side of the module.

+

19V DC power supply

1. Check if Jetson UEFI Firmware version > 36.3

+

Your Jetson Orin Nano Developer Kit may have the latest firmware ("Jetson UEFI firmware" on QSPI-NOR flash memory) flashed at the factory.

+

If not, we need to go through a set of procedures to upgrade to the latest firmware. (Luckily, we can now do this all just on Jetson, meaning we don't need to use a host Ubuntu PC any more!)

+

So let's first check the version of your Jetson UEFI Firmware.
+You can take one of the following methods.

+
+
+
+
    +
  1. Connect your monitor and USB keyboard to your developer kit.
    2. +
  2. Turn on the developer kit by plugging in the bundled DC power supply
    3. +
  3. Repeatedly press Esc key on the keyboard, especially after NVIDIA logo boot splash screen first appears on the monitor
    4. +
  4. You should see UEFI setup menu screen
    5. +
  5. Check the third line from the top (below "Not specified"), which should be the version number of Jetson UEFI firmware
    6. +
+
+
+
    +
  1. Connect USB to TTL Serial cable onto the following pins on J14 "button" header of carrier board located under the Jetson module. +
    2. +
  2. On your PC, run your console monitor program and open the USB serial port.
    3. +
  3. Power on the developer kit by plugging in the bundled DC power supply
    4. +
  4. On the PC console, repeatedly press Esc key on the keyboard, especially after NVIDIA logo boot splash screen first appears on the monitor
    5. +
  5. You should see UEFI setup menu screen
    6. +
  6. Check the third line from the top (below "Not specified"), which should be the version number of Jetson UEFI firmware
    7. +
+
+
+
+

You could skip to 6. Flash JetPack 6.0 GA image onto your microSD card, and try your luck to see if your Jetson just boots your Jetson Orin Nano Developer Kit up to the initial software set up (OEM-config).

+
+
+
+
+

[< 36.0] Upgrade the Jetson UEFI firmware to 36.x

+
+

Attention

+

Select the appropriate tab below based on your firmware version you found in the above step.

+

If you found your Jetson Orin Nano needs its firmware updated to run JetPack 6, click " Firmware < 36.0" tab, and then additional step 2 to 5 will appear for you to follow.

+

If you know your Jetson Orin Nano has the latest firmware, stay on " Firmware 36.x" tab, and skip to the next section (6. Flash JetPack 6.0 GA image onto your microSD card)

+
+
+
+
+
+

Your Jetson Orin Nano has the latest firmware that is ready for JetPack 6 SD card.

+

Skip to the next section (6. Flash JetPack 6.0 GA image onto your microSD card)

+
+
+
+
+

Your Jetson Orin Nano needs its firmware updated in order to make JetPack 6 SD card work.

+

Perform the following steps (2 to 5).

+
+

2. Flash JetPack 5.1.3 image onto your microSD card

+

First we need to run JetPack 5.1.3 in order let its nvidia-l4t-bootloader package to get its bootloader/firmware updater activated, so that the firmware update automatically runs the next time it reboots.

+
    +
  1. +

    Download SD card image on to your PC

    +

    On your PC, download JetPack 5.1.3 image for Jetson Orin Nano Developer Kit from the official JetPack 5.1.3 page or from the below direct link button.

    +

    Jetson Orin Nano Developer Kit
    JetPack 5.1.3 image

    +
    2. +
  2. +

    Use Balena Etcher to flash image to SD card

    +

    If you don't have Balena Etcher on your PC, download from Balena official site.

    +

    +
    3. +
  3. +

    Insert the flashed microSD card into the slot on Jetson module

    +

    +
    4. +
+

3. Power-on and reboot to ensure firmware gets updated to 5.0 (JetPack 5.1.3)

+
    +
  1. +

    Power-on

    +

    Turn on the Jetson Orin Nano Developer Kit with JetPack 5.1.3 SD card inserted by plugging in the DC power supply.

    +
    2. +
  2. +

    Complete the initial software setup (oem-config)

    +
    3. +
  3. +

    Ensure firmware update is scheduled.

    +

    Once Jetson boots into Jetson Linux system, a background service automatically runs to schedule a firmware update (if needed) to be performed during the next boot-up process.

    +

    Once you see the following, or just wait about 5 minutes after powering on to ensure the scheduling is done, reboot.

    +
    +
    +
    +

    +
    +
    +
    $ sudo systemctl status nv-l4t-bootloader-config
+[sudo] password for jetson: 
+● nv-l4t-bootloader-config.service - Configure bootloader service
+    Loaded: loaded (/etc/systemd/system/nv-l4t-bootloader-config.service; enabled; vendor preset: enabled)
+    Active: inactive (dead) since Fri 2024-05-03 13:36:13 PDT; 1min 57s ago
+    Process: 11439 ExecStart=/opt/nvidia/l4t-bootloader-config/nv-l4t-bootloader-config.sh -v (code=exited, status=0/SUCCESS)
+Main PID: 11439 (code=exited, status=0/SUCCESS)
+
    +
    +
    +
    +
    4. +
  4. +

    Reboot

    +

    Reboot your Jetson Orin Nano Developer Kit.

    +

    You should see the following during the boot up process.

    +
    +
    +
    +

    +
    +
    +

    +
    +
    +
    +

    Once done, you will boot into JetPack 5.1.3 (again), with underlying firmware updated to 5.0-35550185.

    +
    5. +
+

4. Install and run QSPI Updater package

+
    +
  1. +

    Double-check your firmware version is up to date (35.5.0 = JetPack 5.1.3)

    +

    Once it reboots back into Jetson Linux system, on Jetson terminal, run the following:

    +
    sudo nvbootctl dump-slots-info
+
    +

    You should see something like the following, with the Current version indicating 35.5.0.

    +
    Current version: 35.5.0
+Capsule update status: 0
+Current bootloader slot: A
+Active bootloader slot: A
+num_slots: 2
+slot: 0,             status: normal
+slot: 1,             status: normal
+
    +
    2. +
  2. +

    Install QSPI Updater Debian package to trigger another (final) firmware update

    +

    On Jetson terminal, run the following:

    +
    sudo apt-get install nvidia-l4t-jetson-orin-nano-qspi-updater
+
    +

    Installing the nvidia-l4t-jetson-orin-nano-qspi-updater automatically runs its script to schedule another (final) firmware update to be performed during the next boot process, so that the firmware is ready for JetPack 6.

    +
    3. +
+

5. Reboot and power-off the developer kit

+
    +
  1. +

    Reboot

    +

    Once the QSPI update is scheduled, reboot your Jetson Orin Nano Developer Kit.

    +
    2. +
  2. +

    Observe update

    +

    You can observe the update during the boot up process.

    +
    3. +
  3. +

    Power off

    +

    Once the update is done, it reboots and tries to boot, however it will get stuck UNLESS you change the SD card to JetPack 6 one.

    +

    Therefore you should just power off the developer kit by disconnecting the DC power supply.

    +
    +

    Attention

    +

    This part may look very confusing as neither the attached monitor nor the debug UART shows any explicit message on what action to take next.

    +

    What is going on here is that the Jetson's firmware (inside the QSPI-NOR flash memory) is now updated, ready for the JetPack 6 SD card, however it is now incompatible with JetPack 5.1.3 SD card left in the Jetson module's slot, so after the reboot it gets stuck in the boot process.

    +

    So there is nothing problematic with this boot halt (or endless rebooting). We just need to power-off and insert a new SD card.

    +
    +
    4. +
+
+
+
+

6. Flash JetPack 6.0 GA image onto your microSD card

+

Once we know the onboard firmware is up-to-date and ready for JetPack 6, we can boot Jetson Orin Nano Developer Kit with a microSD card for JetPack 6.

+
    +
  1. +

    Download SD card image on to your PC

    +

    On your PC, download JetPack 6.0 GA image for Jetson Orin Nano Developer Kit from the official JetPack 6.0 page or from the below direct link button.

    +

    Jetson Orin Nano Developer Kit
    JetPack 6.0 GA image

    +
    2. +
  2. +

    Use Balena Etcher to flash image to SD card

    +

    Insert your microSD card into your PC's SD card slot, and use Balena Etcher to flash the SD card with the image you just downloaded.

    +

    If you don't have Balena Etcher on your PC, download from Balena official site.

+
    +
  1. +

    Insert the JetPack 6 microSD card into the slot on Jetson module

    +

    +
    2. +
  2. +

    Power-on by plugging the DC power supply

    +
    3. +
  3. +

    Complete the initial software setup (oem-config)

    +
    4. +
+

🎊 Congratulations!

Jetson AI Lab Research Group

+

The Jetson AI Lab Research Group is a global collective for advancing open-source Edge ML, open to anyone to join and collaborate with others from the community and leverage each other's work. Our goal is using advanced AI for good in real-world applications in accessible and responsible ways. By coordinating together as a group, we can keep up with the rapidly evolving pace of AI and more quickly arrive at deploying intelligent multimodal agents and autonomous robots into the field.

+

There are virtual meetings that anyone is welcome to join, offline discussion on the Jetson Projects forum, and guidelines for upstreaming open-source contributions.

+
+

Next Meeting - 5/29

+

The next team meeting is on Wednesday, May 29th at 9am PST - see the invite below or click here to join the meeting.

+ +
+

Topics of Interest

+

These are some initial research topics for us to discuss and investigate. This list will vary over time as experiments evolve and the SOTA progresses:

+ + + + + + + + + + + + + + + + + + + + + + + + + +
• Controller LLMs for dynamic pipeline code generation• Fine-tuning LLM/VLM onboard Jetson AGX Orin 64GB
• HomeAssistant.io integration for smart home [1] [2]• Continuous multi-image VLM streaming and change detection
• Recurrent LLM architectures (Mamba, RKVW, ect) [1]• Lightweight low-memory streaming ASR/TTS models
• Diffusion models for image processing and enhancement• Time Series Forecasting with Transformers [1] [2]
• Guidance, grammars, and guardrails for constrained output• Inline LLM function calling / plugins from API definitions
• ML DevOps, edge deployment, and orchestration• Robotics, IoT, and cyberphysical systems integration
+ +

New topics can be raised to the group either during the meetings or on the forums (people are welcome to work on whatever they want of course)

+

Contribution Guidelines

+ + +

When experiments are successful, ideally the results will be packaged in such a way that they are easily reusable for others to integrate into their own projects:

+
+ + + + + + +
+ +

Ongoing technical discussions are encouraged to occur on the forums or GitHub Issues, with status updates on projects given during the meetings.

+

Meeting Schedule

+

We'll aim to meet monthly or bi-weekly as a team in virtual meetings that anyone is welcome to join and speak during. We'll discuss the latest updates and experiments that we want to explore. Please remain courteous to others during the calls. We'll stick around after for anyone who has questions or didn't get the chance to be heard.

+
+

Wednesday, May 29 at 9am PST (5/29/24)

+ +
+ + +

The agenda will be listed here beforehand - post to the forum to add agenda items. The meetings will be recorded so anyone unable to attend live can watch them after.

RAM Optimization

+

Running a LLM requires a huge RAM space.

+

Especially if you are on Jetson Orin Nano that only has 8GB of RAM, it is crucial to leave as much RAM space available for models.

+

Here we share a couple of ways to optimize the system RAM usage.

+

Disabling the Desktop GUI

+

If you use your Jetson remotely through SSH, you can disable the Ubuntu desktop GUI.
+This will free up extra memory that the window manager and desktop uses (around ~800MB for Unity/GNOME).

+

You can disable the desktop temporarily, run commands in the console, and then re-start the desktop when desired:

+
$ sudo init 3     # stop the desktop
+# log your user back into the console (Ctrl+Alt+F1, F2, ect)
+$ sudo init 5     # restart the desktop
+
+

If you wish to make this persistent across reboots, you can use the following commands to change the boot-up behavior:

+
    +
  • +

    To disable desktop on boot

    +
    sudo systemctl set-default multi-user.target
+
    +
    • +
  • +

    To enable desktop on boot

    +
    sudo systemctl set-default graphical.target
+
    +
    • +
+

Disabling misc services

+
sudo systemctl disable nvargus-daemon.service
+
+

Mounting Swap

+

If you're building containers or working with large models, it's advisable to mount SWAP (typically correlated with the amount of memory in the board). Run these commands to disable ZRAM and create a swap file:

+
+

If you have NVMe SSD storage available, it's preferred to allocate the swap file on the NVMe SSD.

+
+
sudo systemctl disable nvzramconfig
+sudo fallocate -l 16G /ssd/16GB.swap
+sudo mkswap /ssd/16GB.swap
+sudo swapon /ssd/16GB.swap
+
+

Then add the following line to the end of /etc/fstab to make the change persistent:

+
/ssd/16GB.swap  none  swap  sw 0  0
+
+ + + + + + + + + + + + + + + +
+
+ + + + + +

Tips - SSD + Docker

+

Once you have your Jetson set up by flashing the latest Jetson Linux (L4T) BSP on it or by flashing the SD card with the whole JetPack image, before embarking on testing out all the great generative AI application using jetson-containers, you want to make sure you have a huge storage space for all the containers and the models you will download.

+

We are going to show how you can install SSD on your Jetson, and set it up for Docker.

+

SSD

+

Physical installation

+
    +
  1. Unplug power and any peripherals from the Jetson developer kit.
    2. +
  2. Physically install an NVMe SSD card on the carrier board of your Jetson developer kit, making sure to properly seat the connector and secure with the screw.
    3. +
  3. Reconnect any peripherals, and then reconnect the power supply to turn on the Jetson developer kit.
    4. +
  4. +

    Once the system is up, verify that your Jetson identifies a new memory controller on PCI bus:

    +
    lspci
+
    +

    The output should look like the following:

    +
    0007:01:00.0 Non-Volatile memory controller: Marvell Technology Group Ltd. Device 1322 (rev 02)
+
    +
    5. +
+

Format and set up auto-mount

+
    +
  1. +

    Run lsblk to find the device name.

    +
    lsblk
+
    +

    The output should look like the following:

    +
    NAME         MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
+loop0          7:0    0    16M  1 loop

+├─mmcblk1p13 179:13   0    64M  0 part 
+└─mmcblk1p14 179:14   0 879.5M  0 part 
+zram0        251:0    0   1.8G  0 disk [SWAP]
+zram1        251:1    0   1.8G  0 disk [SWAP]
+zram2        251:2    0   1.8G  0 disk [SWAP]

+nvme0n1      259:0    0 238.5G  0 disk 
+
    +

    Identify the device corresponding to your SSD. In this case, it is nvme0n1.

    +
    2. +
  2. +

    Format the SSD, create a mount point, and mount it to the filesystem.

    +
    sudo mkfs.ext4 /dev/nvme0n1
+
    +
    +

    You can choose any name for the mount point directory. We use /ssd here, but in jetson-containers' setup.md documentation, /mnt is used.

    +
    +
    sudo mkdir /ssd
+
    +
    sudo mount /dev/nvme0n1 /ssd
+
    +
    3. +
  3. +

    In order to ensure that the mount persists after boot, add an entry to the fstab file:

    +

    First, identify the UUID for your SSD:

    +
    lsblk -f
+
    +

    Then, add a new entry to the fstab file:

    +
    sudo vi /etc/fstab
+
    +

    Insert the following line, replacing the UUID with the value found from lsblk -f:

    +
    UUID=************-****-****-****-******** /ssd/ ext4 defaults 0 2
+
    +
    4. +
  4. +

    Finally, change the ownership of the /ssd directory.

    +
    sudo chown ${USER}:${USER} /ssd
+
    +
    5. +
+

Docker

+
    +
  1. +

    Install nvidia-container package.

    +
    +

    Note: If you used an NVIDIA-supplied SD card image to flash your SD card, all necessary JetPack components (including nvidia-containers) and Docker are already pre-installed, so this step can be skipped.

    +
    +
    sudo apt update
+sudo apt install -y nvidia-container
+
    +
    +

    JetPack 6.0 DP users

    +

    If you flash Jetson Linux (L4T) R36.2 (JetPack 6.0 DP) on your Jetson using SDK Manager, and install nvidia-container using apt, on JetPack 6.0 it no longer automatically installs Docker.

    +

    Therefore, you need to run the following to manually install Docker and set it up.

    +
    sudo apt update
+sudo apt install -y nvidia-container curl
+curl https://get.docker.com | sh && sudo systemctl --now enable docker
+sudo nvidia-ctk runtime configure --runtime=docker
+
    +
    +
    2. +
  2. +

    Restart the Docker service and add your user to the docker group, so that you don't need to use the command with sudo.

    +
    sudo systemctl restart docker
+sudo usermod -aG docker $USER
+newgrp docker
+
    +
    3. +
  3. +

    Add default runtime in /etc/docker/daemon.json

    +
    sudo vi /etc/docker/daemon.json
+
    +

    Insert the "default-runtime": "nvidia" line as following:

    +
    {
+    "runtimes": {
+        "nvidia": {
+            "path": "nvidia-container-runtime",
+            "runtimeArgs": []
+        }
+    },
+    "default-runtime": "nvidia"
+}
+
    +
    4. +
  4. +

    Restart Docker

    +
    sudo systemctl daemon-reload && sudo systemctl restart docker
+
    +
    5. +
+

Migrate Docker directory to SSD

+

Now that the SSD is installed and available on your device, you can use the extra storage capacity to hold the storage-demanding Docker directory.

+
    +
  1. +

    Stop the Docker service.

    +
    sudo systemctl stop docker
+
    +
    2. +
  2. +

    Move the existing Docker folder

    +
    sudo du -csh /var/lib/docker/ && \
+    sudo mkdir /ssd/docker && \
+    sudo rsync -axPS /var/lib/docker/ /ssd/docker/ && \
+    sudo du -csh  /ssd/docker/ 
+
    +
    3. +
  3. +

    Edit /etc/docker/daemon.json

    +
    sudo vi /etc/docker/daemon.json
+
    +

    Insert "data-root" line like the following.

    +
    {
+    "runtimes": {
+        "nvidia": {
+            "path": "nvidia-container-runtime",
+            "runtimeArgs": []
+        }
+    },
+    "default-runtime": "nvidia",
+    "data-root": "/ssd/docker"
+}
+
    +
    4. +
  4. +

    Rename the old Docker data directory

    +
    sudo mv /var/lib/docker /var/lib/docker.old
+
    +
    5. +
  5. +

    Restart the docker daemon

    +
    sudo systemctl daemon-reload && \
+    sudo systemctl restart docker && \
+    sudo journalctl -u docker
+
    +
    6. +
+

Test Docker on SSD

+
    +
  1. +

    [Terminal 1] First, open a terminal to monitor the disk usage while pulling a Docker image.

    +
    watch -n1 df 
+
    +
    2. +
  2. +

    [Terminal 2] Next, open a new terminal and start Docker pull.

    +
    docker pull nvcr.io/nvidia/l4t-base:r35.2.1
+
    +
    3. +
  3. +

    [Terminal 1] Observe that the disk usage on /ssd goes up as the container image is downloaded and extracted.

    +
    ~$ docker image ls
+REPOSITORY                  TAG       IMAGE ID       CREATED        SIZE
+nvcr.io/nvidia/l4t-base     r35.2.1   dc07eb476a1d   7 months ago   713MB
+
    +
    4. +
+

Final Verification

+

Reboot your Jetson, and verify that you observe the following:

+
~$ sudo blkid | grep nvme

Tutorial - API Examples

+

It's good to know the code for generating text with LLM inference, and ancillary things like tokenization, chat templates, and prompting. On this page we give Python examples of running various LLM APIs, and their benchmarks.

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)⚠️

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35) +JetPack 6 (L4T r36)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 22GB for l4t-text-generation container image
      • +
    • Space for models (>10GB)
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

Transformers

+

The HuggingFace Transformers API is the de-facto API that models are released for, often serving as the reference implementation. It's not terribly fast, but it does have broad model support, and also supports quantization (AutoGPTQ, AWQ). This uses streaming:

+
from transformers import AutoModelForCausalLM, AutoTokenizer, TextIteratorStreamer
+from threading import Thread
+
+model_name='meta-llama/Llama-2-7b-chat-hf'
+model = AutoModelForCausalLM.from_pretrained(model_name, device_map='cuda')
+
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+streamer = TextIteratorStreamer(tokenizer)
+
+prompt = [{'role': 'user', 'content': 'Can I get a recipe for French Onion soup?'}]
+inputs = tokenizer.apply_chat_template(
+    prompt,
+    add_generation_prompt=True,
+    return_tensors='pt'
+).to(model.device)
+
+Thread(target=lambda: model.generate(inputs, max_new_tokens=256, streamer=streamer)).start()
+
+for text in streamer:
+    print(text, end='', flush=True)
+
+

To run this (it can be found here), you can mount a directory containing the script or your jetson-containers directory:

+
jetson-containers run --volume $PWD/packages/llm:/mount --workdir /mount \
+  $(autotag l4t-text-generation) \
+    python3 transformers/test.py
+
+

We use the l4t-text-generation container because it includes the quantization libraries in addition to Transformers, for running the quanztized versions of the models like TheBloke/Llama-2-7B-Chat-GPTQ

+

Benchmarks

+

The huggingface-benchmark.py script will benchmark the models:

+
./run.sh --volume $PWD/packages/llm/transformers:/mount --workdir /mount \
+  $(./autotag l4t-text-generation) \
+    python3 huggingface-benchmark.py --model meta-llama/Llama-2-7b-chat-hf

NanoLLM

+

The NanoLLM library uses the optimized MLC/TVM library for inference, like on the Benchmarks page:

+

+
> NanoLLM Reference Documentation
from nano_llm import NanoLLM, ChatHistory, ChatTemplates
+
+# load model
+model = NanoLLM.from_pretrained(
+    model='meta-llama/Meta-Llama-3-8B-Instruct', 
+    quantization='q4f16_ft', 
+    api='mlc'
+)
+
+# create the chat history
+chat_history = ChatHistory(model, system_prompt="You are a helpful and friendly AI assistant.")
+
+while True:
+    # enter the user query from terminal
+    print('>> ', end='', flush=True)
+    prompt = input().strip()
+
+    # add user prompt and generate chat tokens/embeddings
+    chat_history.append(role='user', msg=prompt)
+    embedding, position = chat_history.embed_chat()
+
+    # generate bot reply
+    reply = model.generate(
+        embedding, 
+        streaming=True, 
+        kv_cache=chat_history.kv_cache,
+        stop_tokens=chat_history.template.stop,
+        max_new_tokens=256,
+    )
+
+    # append the output stream to the chat history
+    bot_reply = chat_history.append(role='bot', text='')
+
+    for token in reply:
+        bot_reply.text += token
+        print(token, end='', flush=True)
+
+    print('\n')
+
+    # save the inter-request KV cache 
+    chat_history.kv_cache = reply.kv_cache
+
+

This example keeps an interactive chat running with text being entered from the terminal. You can start it like this:

+
jetson-containers run \
+  --env HUGGINGFACE_TOKEN=hf_abc123def \
+  $(autotag nano_llm) \
+    python3 -m nano_llm.chat.example
+
+

Or for easy editing from the host device, copy the source into your own script and mount it into the container with the --volume flag. And for authenticated models, request access through HuggingFace (like with Llama) and substitute your account's API token above.

Tutorial - AudioCraft

+

Let's run Meta's AudioCraft, to produce high-quality audio and music on Jetson!

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin Nano (8GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 10.7 GB for audiocraft container image
      • +
    • Space for checkpoints
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

How to start

+

Use run.sh and autotag script to automatically pull or build a compatible container image.

+
jetson-containers run $(autotag audiocraft)
+
+

The container has a default run command (CMD) that will automatically start the Jupyter Lab server.

+

Open your browser and access http://<IP_ADDRESS>:8888.

+
+

The default password for Jupyter Lab is nvidia.

+
+

Run Jupyter notebooks

+

AudioCraft repo comes with demo Jupyter notebooks.

+

On Jupyter Lab navigation pane on the left, double-click demos folder.

+

+

AudioGen demo

+ + +

Run cells with Shift + Enter, first one will download models, which can take some time.

+
+

Info

+

You may encounter an error message like the following when executing the first cell, but you can keep going. +

A matching Triton is not available, some optimizations will not be enabled.
+Error caught was: No module named 'triton'
+

+
+ + +

In the Audio Continuation cells, you can generate continuation based on text, while in Text-conditional Generation you can generate audio based just on text descriptions.

+

You can also use your own audio as prompt, and use text descriptions to generate continuation: +

prompt_waveform, prompt_sr = torchaudio.load("../assets/sirens_and_a_humming_engine_approach_and_pass.mp3") # you can upload your own audio
+prompt_duration = 2
+prompt_waveform = prompt_waveform[..., :int(prompt_duration * prompt_sr)]
+output = model.generate_continuation(prompt_waveform.expand(3, -1, -1), prompt_sample_rate=prompt_sr,descriptions=[
+        'Subway train blowing its horn',   # text descriptions for continuation
+        'Horse neighing furiously',
+        'Cat hissing'
+], progress=True)
+display_audio(output, sample_rate=16000)
+

+

MusicGen and MAGNeT demos

+

The two other jupyter notebooks are similar to AuidioGen, where you can generate continuation or generate audio, while using models trained to generate music.

Tutorial - Live LLaVA

+
+

Recommended

+

Follow the chat-based LLaVA and NanoVLM tutorials to familiarize yourself with vision/language models and test the models first.

+
+

This multimodal agent runs a vision-language model on a live camera feed or video stream, repeatedly applying the same prompts to it:

+

+

It uses models like LLaVA or VILA and has been quantized with 4-bit precision. This runs an optimized multimodal pipeline from the NanoLLM library, including running the CLIP/SigLIP vision encoder in TensorRT, event filters and alerts, and multimodal RAG (see the NanoVLM page for benchmarks)

+

+

Running the Live Llava Demo

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)⚠️

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 22GB for nano_llm container image
      • +
    • Space for models (>10GB)
      • +
    +
    4. +
  4. +

    Follow the chat-based LLaVA and NanoVLM tutorials first.

    +
    5. +
  5. +

    Supported vision/language models:

    + +
    6. +
+
+

The VideoQuery agent applies prompts to the incoming video feed with the VLM. Navigate your browser to https://<IP_ADDRESS>:8050 after launching it with your camera (Chrome is recommended with chrome://flags#enable-webrtc-hide-local-ips-with-mdns disabled)

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.agents.video_query --api=mlc \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-context-len 256 \
+    --max-new-tokens 32 \
+    --video-input /dev/video0 \
+    --video-output webrtc://@:8554/output
+
+

+

This uses jetson_utils for video I/O, and for options related to protocols and file formats, see Camera Streaming and Multimedia. In the example above, it captures a V4L2 USB webcam connected to the Jetson (under the device /dev/video0) and outputs a WebRTC stream.

+

Processing a Video File or Stream

+

The example above was running on a live camera, but you can also read and write a video file or network stream by substituting the path or URL to the --video-input and --video-output command-line arguments like this:

+
jetson-containers run \
+  -v /path/to/your/videos:/mount
+  $(autotag nano_llm) \
+    python3 -m nano_llm.agents.video_query --api=mlc \
+      --model Efficient-Large-Model/VILA1.5-3b \
+      --max-context-len 256 \
+      --max-new-tokens 32 \
+      --video-input /mount/my_video.mp4 \
+      --video-output /mount/output.mp4 \
+      --prompt "What does the weather look like?"
+
+

This example processes and pre-recorded video (in MP4, MKV, AVI, FLV formats with H.264/H.265 encoding), but it also can input/output live network streams like RTP, RTSP, and WebRTC using Jetson's hardware-accelerated video codecs.

+

NanoDB Integration

+

If you launch the VideoQuery agent with the --nanodb flag along with a path to your NanoDB database, it will perform reverse-image search on the incoming feed against the database by re-using the CLIP embeddings generated by the VLM.

+

To enable this mode, first follow the NanoDB tutorial to download, index, and test the database. Then launch VideoQuery like this:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.agents.video_query --api=mlc \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-context-len 256 \
+    --max-new-tokens 32 \
+    --video-input /dev/video0 \
+    --video-output webrtc://@:8554/output \
+    --nanodb /data/nanodb/coco/2017
+
+

You can also tag incoming images and add them to the database using the web UI, for one-shot recognition tasks:

+
+ +
+ +

Video VILA

+

The VILA-1.5 family of models can understand multiple images per query, enabling video search/summarization, action & behavior analysis, change detection, and other temporal-based vision functions. The vision/video.py example keeps a rolling history of frames:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.vision.video \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-images 8 \
+    --max-new-tokens 48 \
+    --video-input /data/my_video.mp4 \
+    --video-output /data/my_output.mp4 \
+    --prompt 'What changes occurred in the video?'
+
+

+

Note: support will be added to the web UI for continuous multi-image queries on video sequences.

+

Python Code

+

For a simplified code example of doing live VLM streaming from Python, see here in the NanoLLM docs.

+ + +

You can use this to implement customized prompting techniques and integrate with other vision pipelines. This code applies the same set of prompts to the latest image from the video feed. See here for the version that does multi-image queries on video sequences.

Tutorial - llamaspeak

+

Talk live with Llama using streaming ASR/TTS, and chat about images with Llava!

+

+
    +
  • The NanoLLM library provides optimized inference for LLM and speech models.
    • +
  • It's recommended to run JetPack 6.0 to be able to run the latest containers.
    • +
+

The WebChat agent has responsive conversational abilities and multimodal support for chatting about images with vision/language models, including overlapping ASR/LLM/TTS generation and verbal interruptability.

+

Running llamaspeak

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 6 (L4T r36)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 22GB for nano_llm container image
      • +
    • Space for models (>10GB)
      • +
    +
    4. +
  4. +

    Start the Riva server first and test the ASR examples.

    +
    5. +
+
+
jetson-containers run --env HUGGINGFACE_TOKEN=hf_xyz123abc456 \
+  $(autotag nano_llm) \
+  python3 -m nano_llm.agents.web_chat --api=mlc \
+    --model meta-llama/Meta-Llama-3-8B-Instruct \
+    --asr=riva --tts=piper
+
+

This will start llamaspeak with text LLM and ASR/TTS enabled. You can then navigate your browser to https://IP_ADDRESS:8050 + +

    +
  • The default port is 8050, but can be changed with --web-port (and --ws-port for the websocket port)
    • +
  • During bot replies, the TTS model will pause output if you speak a few words in the mic to interrupt it.
    • +
  • Request access to the Llama models on HuggingFace and substitute your account's API token above.
    • +
+

+ + +

The code and docs for the WebAgent that runs llamaspeak can be found in the NanoLLM library. This block diagram shows the speech pipeline with interleaved model generation, user interruption, and streaming I/O:

+

+

Multimodality

+

If you load a multimodal vision/language model instead, you can drag images into the chat and ask questions about them:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.agents.web_chat --api=mlc \
+    --model Efficient-Large-Model/VILA-7b \
+    --asr=riva --tts=piper
+
+ + +

For more info about the supported vision/language models, see the NanoVLM page.

+

Function Calling

+

There's the ability to define functions from Python that the bot has access to and can invoke based on the chat flow:

+ + +

This works by using the bot_function() decorator and adding the API description's to the system prompt:

+
from nano_llm import NanoLLM, ChatHistory, BotFunctions, bot_function
+from datetime import datetime
+
+@bot_function
+def DATE():
+    """ Returns the current date. """
+    return datetime.now().strftime("%A, %B %-m %Y")
+
+@bot_function
+def TIME():
+    """ Returns the current time. """
+    return datetime.now().strftime("%-I:%M %p")
+
+system_prompt = "You are a helpful and friendly AI assistant." + BotFunctions.generate_docs()
+
+

The system prompt can be autogenerated from the Python docstrings embedded in the functions themselves, and can include parameters that the bot can supply (for example, selectively saving relevant user info to a vector database for RAG like is shown in the video).

+

For more information about this topic, see the Function Calling section of the NanoLLM documentation.

Tutorial - LLaVA

+

LLaVA is a popular multimodal vision/language model that you can run locally on Jetson to answer questions about image prompts and queries. Llava uses the CLIP vision encoder to transform images into the same embedding space as its LLM (which is the same as Llama architecture). Below we cover different methods to run Llava on Jetson, with increasingly optimized performance:

+
    +
  1. Chat with Llava using text-generation-webui
    2. +
  2. Run from the terminal with llava.serve.cli
    3. +
  3. Quantized GGUF models with llama.cpp
    4. +
  4. Optimized Multimodal Pipeline with NanoVLM
    5. +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+    --model-path liuhaotian/llava-v1.5-7b \
+    --image-file /data/images/hoover.jpg
+
+

jetson-containers run $(autotag llava) \
+  python3 -m llava.serve.cli \
+    --model-path liuhaotian/llava-v1.5-13b \
+    --image-file /data/images/hoover.jpg
+
+
+

Unquantized 13B may run only on Jetson AGX Orin 64GB due to memory requirements.

+
+ + +

3. Quantized GGUF models with llama.cpp

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x) +JetPack 6 (L4T r36.x)

    +
    3. +
+
+

llama.cpp is one of the faster LLM API's, and can apply a variety of quantization methods to Llava to reduce its memory usage and runtime. Despite its name, it uses CUDA. There are pre-quantized versions of Llava-1.5 available in GGUF format for 4-bit and 5-bit:

+ +
jetson-containers run --workdir=/opt/llama.cpp/bin $(autotag llama_cpp:gguf) \
+  /bin/bash -c './llava-cli \
+    --model $(huggingface-downloader mys/ggml_llava-v1.5-13b/ggml-model-q4_k.gguf) \
+    --mmproj $(huggingface-downloader mys/ggml_llava-v1.5-13b/mmproj-model-f16.gguf) \
+    --n-gpu-layers 999 \
+    --image /data/images/hoover.jpg \
+    --prompt "What does the sign say"'
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + +
QuantizationBitsResponseTokens/secMemory
Q4_K4The sign says "Hoover Dam, Exit 9."10.179.2 GB
Q5_K5The sign says "Hoover Dam exit 9."9.7310.4 GB
+

A lower temperature like 0.1 is recommended for better quality (--temp 0.1), and if you omit --prompt it will describe the image:

+
jetson-containers run --workdir=/opt/llama.cpp/bin $(autotag llama_cpp:gguf) \
+  /bin/bash -c './llava-cli \
+    --model $(huggingface-downloader mys/ggml_llava-v1.5-13b/ggml-model-q4_k.gguf) \
+    --mmproj $(huggingface-downloader mys/ggml_llava-v1.5-13b/mmproj-model-f16.gguf) \
+    --n-gpu-layers 999 \
+    --image /data/images/lake.jpg'
+
+In this image, a small wooden pier extends out into a calm lake, surrounded by tall trees and mountains. The pier seems to be the only access point to the lake. The serene scene includes a few boats scattered across the water, with one near the pier and the others further away. The overall atmosphere suggests a peaceful and tranquil setting, perfect for relaxation and enjoying nature.
+
+

You can put your own images in the mounted jetson-containers/data directory. The C++ code for llava-cli can be found here. The llama-cpp-python bindings also support Llava, however they are significantly slower from Python for some reason (potentially pre-processing)

17# First steps with Metropolis Microservices for Jetson

+

NVIDIA Metropolis Microservices for Jetson simplifies the development of vision AI applications, offering a suite of customizable, cloud-native tools. Before diving into this tutorial, ensure you've filled out the Metropolis Microservices for Jetson Early Access form to gain the necessary access to launch the services. This step is crucial as it enables you to utilize all the features and capabilities discussed in this guide.

+

Perfect for both newcomers and experts, this tutorial provides straightforward steps to kick-start your edge AI projects. Whether you're a student or an ecosystem partner working on a use case, this guide offers a straightforward start for every skill level.

+

+

0. Install NVIDIA Jetson Services:

+

Ok, let's start by installing NVIDIA Jetson Services: +

sudo apt install nvidia-jetson-services
+

+

Let's add some performance hacks that will be needed to run the demo faster and without streaming artifacts:

+
    +
  • +

    If you don't have the Orin at max performance, you can use these two commands, a reboot is needed after: +

    sudo nvpmodel -m 0 
+sudo jetson_clocks
+

    +
    • +
  • +

    After these two commands, a reboot is needed if your Jetson wasn't already in high-performance mode. +These are optional, but they fine-tune your network buffers to ensure smoother streaming by optimizing how much data can be sent and received: +

    sudo sysctl -w net.core.rmem_default=2129920
+sudo sysctl -w net.core.rmem_max=10000000
+sudo sysctl -w net.core.wmem_max=2000000
+

    +
    • +
+
+

1. Download NVIDIA CLI for Jetson

+

Download NGC for ARM64 from the NGC for CLI site: +

unzip ngccli_arm64.zip
+chmod u+x ngc-cli/ngc
+echo "export PATH=\"\$PATH:$(pwd)/ngc-cli\"" >> ~/.bash_profile && source ~/.bash_profile
+ngc config set
+
+Here it will ask for your API Key, and the organization name, to get those you need to login into NGC and generate an API key here.

+

You should then paste the API key and use the organization name you are using. You can also press [Enter] to select the default values for the remaining options. After this, you should get the message:

+
Successfully saved NGC configuration to /home/jetson/.ngc/config
+
+

Then, login with the same API key: +

sudo docker login nvcr.io -u "\$oauthtoken" -p <NGC-API-KEY>
+

+

Now launch the Redis and Ingress services, as we need them for this tutorial.

+
sudo systemctl start jetson-redis
+sudo systemctl start jetson-ingress
+
+
+

2. Download and launch NVStreamer

+

+

First, we need to install NVStreamer, an app that streams the videos MMJs will need to run AI on them. Follow this NVStreamer Link (In the top-left, click Download files.zip)

+

unzip files.zip
+rm files.zip
+tar -xvf nvstreamer.tar.gz
+cd nvstreamer
+
+Launch it: +
sudo docker compose -f compose_nvstreamer.yaml up -d  --force-recreate
+

+
+

3. Download AI_NVR and launch:

+

+

AI NVR (NGC) Link (Top-left -> Download files.zip)

+
unzip files.zip
+rm files.zip
+tar -xvf ai_nvr.tar.gz
+sudo cp ai_nvr/config/ai-nvr-nginx.conf /opt/nvidia/jetson/services/ingress/config/
+cd ai_nvr
+sudo docker compose -f compose_agx.yaml up -d --force-recreate
+
+

4. Download some sample videos and upload them to NVStreamer

+

Download them from here.

+

unzip files.zip
+
+Ok, now, this is important to understand, there are 2 web interfaces:

+
    +
  1. The NVStream Streamer Dashboard, running in: http://localhost:31000
    2. +
  2. The NVStreamer Camera Management Dashboard, running in: http://localhost:31000
    3. +
+

So, first we need to upload the file in the Streamer interface, it looks like this:

+
+

image1

+
+

There, go to File Upload, and drag and drop the file in the upload squared area.

+

After uploading it, go to the Dashboad option of the left menu, and copy the RTSP URL of the video you just uploaded, you will need it for the Camera Management Dashboard.

+

Now jump to the Camera Management Dashboard (http://localhost:30080/vst), it looks like this:

+
+

image2

+
+

Go to the Camera Management option of the menu, then use the Add device manually option, and paste the RTSP URL, add the name of your video to the Name and Location text boxes, so it will be displayed on top of the stream.

+

Finally, click in the Live Streams option of the left menu, and you should be able to watch your video stream.

+
+

video1

+
+

5. Watch RTSP AI processed streaming from VLC

+

Open VLC from another computer (localhost doesn't work here), and point to your Jetson Orin's IP address (you should be in the same network, or not having a firewal to access).

+

The easiest way to get Jetson's ip is launching: +

ifconfig
+
+And checking the IP of the interface (usually wlan0, inet IP).

+

Then go to rtsp://[JETSON_IP]:8555/ds-test using VLC like this:

+
+

video2

+
+

6. Android app

+

There is an Android app that allows you to track events and create areas of interest to monitor, you can find it on Google Play as AI NVR.

+

+
+

Here is a quick walkthough where you can see how to:

+
    +
  • Add the IP address of the Jetson
    • +
  • Track current events
    • +
  • Add new areas of interest
    • +
  • Add tripwire to track the flux and direction of events
    • +

NanoLLM - Optimized LLM Inference

+

NanoLLM is a lightweight, high-performance library using optimized inferencing APIs for quantized LLM’s, multimodality, speech services, vector databases with RAG, and web frontends. It's used to build many of the responsive, low-latency agents featured on this site.

+

+

It provides similar APIs to HuggingFace, backed by highly-optimized inference libraries and quantization tools:

+
NanoLLM Reference Documentation
from nano_llm import NanoLLM
+
+model = NanoLLM.from_pretrained(
+   "meta-llama/Meta-Llama-3-8B-Instruct",  # HuggingFace repo/model name, or path to HF model checkpoint
+   api='mlc',                              # supported APIs are: mlc, awq, hf
+   api_token='hf_abc123def',               # HuggingFace API key for authenticated models ($HUGGINGFACE_TOKEN)
+   quantization='q4f16_ft'                 # q4f16_ft, q4f16_1, q8f16_0 for MLC, or path to AWQ weights
+)
+
+response = model.generate("Once upon a time,", max_new_tokens=128)
+
+for token in response:
+   print(token, end='', flush=True)
+
+

Containers

+

To test a chat session with Llama from the command-line, install jetson-containers and run NanoLLM like this:

+

git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
+
jetson-containers run \
+  --env HUGGINGFACE_TOKEN=hf_abc123def \
+  $(autotag nano_llm) \
+  python3 -m nano_llm.chat --api mlc \
+    --model meta-llama/Meta-Llama-3-8B-Instruct \
+    --prompt "Can you tell me a joke about llamas?"
+

+

If you haven't already, request access to the Llama models on HuggingFace and substitute your account's API token above.

+

NanoVLM - Efficient Multimodal Pipeline

+

We saw in the previous LLaVA tutorial how to run vision-language models through tools like text-generation-webui and llama.cpp. In a similar vein to the SLM page on Small Language Models, here we'll explore optimizing VLMs for reduced memory usage and higher performance that reaches interactive levels (like in Liva LLava). These are great for fitting on Orin Nano and increasing the framerate.

+

There are 3 model families currently supported: Llava, VILA, and Obsidian (mini VLM)

+

VLM Benchmarks

+ + +

This FPS measures the end-to-end pipeline performance for continuous streaming like with Live Llava (on yes/no question)

+ + +

Multimodal Chat

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)⚠️

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 6 (L4T r36)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 22GB for nano_llm container image
      • +
    • Space for models (>10GB)
      • +
    +
    4. +
  4. +

    Supported VLM models in NanoLLM:

    + +
    5. +
+
+

The optimized NanoLLM library uses MLC/TVM for quantization and inference provides the highest performance. It efficiently manages the CLIP embeddings and KV cache. You can find Python code for the chat program used in this example here.

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.chat --api=mlc \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-context-len 256 \
+    --max-new-tokens 32
+
+

This starts an interactive console-based chat with Llava, and on the first run the model will automatically be downloaded from HuggingFace and quantized using MLC and W4A16 precision (which can take some time). See here for command-line options.

+

You'll end up at a >> PROMPT: in which you can enter the path or URL of an image file, followed by your question about the image. You can follow-up with multiple questions about the same image. Llava does not understand multiple images in the same chat, so when changing images, first reset the chat history by entering clear or reset as the prompt. VILA supports multiple images (area of active research)

+

Automated Prompts

+

During testing, you can specify prompts on the command-line that will run sequentially:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.chat --api=mlc \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-context-len 256 \
+    --max-new-tokens 32 \
+    --prompt '/data/images/hoover.jpg' \
+    --prompt 'what does the road sign say?' \
+    --prompt 'what kind of environment is it?' \
+    --prompt 'reset' \
+    --prompt '/data/images/lake.jpg' \
+    --prompt 'please describe the scene.' \
+    --prompt 'are there any hazards to be aware of?'
+
+

You can also use --prompt /data/prompts/images.json to run the test sequence, the results of which are in the table below.

+

Results

+ + +

•   The model responses are with 4-bit quantization enabled, and are truncated to 128 tokens for brevity.
+•   These chat questions and images are from /data/prompts/images.json (found in jetson-containers)

+

JSON

+

When prompted, these models can also output in constrained JSON formats (which the LLaVA authors cover in their LLaVA-1.5 paper), and can be used to programatically query information about the image:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.chat --api=mlc \
+    --model liuhaotian/llava-v1.5-13b \
+    --prompt '/data/images/hoover.jpg' \
+    --prompt 'extract any text from the image as json'
+
+{
+  "sign": "Hoover Dam",
+  "exit": "2",
+  "distance": "1 1/2 mile"
+}
+
+

Web UI

+

To use this through a web browser instead, see the llamaspeak tutorial:

+

+

Live Streaming

+

These models can also be used with the Live Llava agent for continuous streaming - just substitute the desired model name below:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.agents.video_query --api=mlc \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-context-len 256 \
+    --max-new-tokens 32 \
+    --video-input /dev/video0 \
+    --video-output webrtc://@:8554/output
+
+

Then navigate your browser to https://<IP_ADDRESS>:8050 after launching it with your camera. Using Chrome or Chromium is recommended for a stable WebRTC connection, with chrome://flags#enable-webrtc-hide-local-ips-with-mdns disabled.

+

The Live Llava tutorial shows how to enable additional features like vector database integration, image tagging, and RAG.

+
+ +
+ +

Video Sequences

+

The VILA-1.5 family of models can understand multiple images per query, enabling video search/summarization, action & behavior analysis, change detection, and other temporal-based vision functions. By manipulating the KV cache and dropping off the last frame from the chat history, we can keep the stream rolling continuously beyond the maximum context length of the model. The vision/video.py example shows how to use this:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.vision.video \
+    --model Efficient-Large-Model/VILA1.5-3b \
+    --max-images 8 \
+    --max-new-tokens 48 \
+    --video-input /data/my_video.mp4 \
+    --video-output /data/my_output.mp4 \
+    --prompt 'What changes occurred in the video?'
+
+ +

Note: support will be added to the web UI for continuous multi-image queries on video sequences and is WIP.

+

Python Code

+

For a simplified code example of doing live VLM streaming from Python, see here in the NanoLLM docs.

+ + +

You can use this to implement customized prompting techniques and integrate with other vision pipelines. This code applies the same set of prompts to the latest image from the video feed. See here for the version that does multi-image queries on video sequences.

Let's run NanoDB's interactive demo to witness the impact of Vector Database that handles multimodal data.

+

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x) +JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 16GB for container image
      • +
    • 40GB for MS COCO dataset
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

How to start

+

Download COCO

+

Just for an example, let's use MS COCO dataset:

+
cd jetson-containers
+mkdir -p data/datasets/coco/2017
+cd data/datasets/coco/2017
+
+wget http://images.cocodataset.org/zips/train2017.zip
+wget http://images.cocodataset.org/zips/val2017.zip
+wget http://images.cocodataset.org/zips/unlabeled2017.zip
+
+unzip train2017.zip
+unzip val2017.zip
+unzip unlabeled2017.zip
+
+

Download Index

+

You can download a pre-indexed NanoDB that was already prepared over the COCO dataset from here:

+
cd jetson-containers/data
+wget https://nvidia.box.com/shared/static/icw8qhgioyj4qsk832r4nj2p9olsxoci.gz -O nanodb_coco_2017.tar.gz
+tar -xzvf nanodb_coco_2017.tar.gz
+
+

This allow you to skip the indexing process in the next step, and jump to starting the Web UI.

+

Indexing Data

+

If you didn't download the NanoDB index for COCO from above, we need to build the index by scanning your dataset directory:

+
jetson-containers run $(autotag nanodb) \
+  python3 -m nanodb \
+    --scan /data/datasets/coco/2017 \
+    --path /data/nanodb/coco/2017 \
+    --autosave --validate 
+
+

This will take a few hours on AGX Orin. Once the database has loaded and completed any start-up operations , it will drop down to a > prompt from which the user can run search queries. You can quickly check the operation by typing your query on this prompt:

+

Tutorial - Ollama

+

Ollama is a popular LLM tool that's easy to get started with, and includes a built-in model library of pre-quantized weights that will automatically be downloaded and run using llama.cpp underneath for inference. The ollama container was compiled with CUDA support.

+

+ +

Ollama Server

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x) +JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 7GB for ollama container image
      • +
    • Space for models (>5GB)
      • +
    +
    4. +
+
+
# models cached under jetson-containers/data
+jetson-containers run --name ollama $(autotag ollama)
+
+# models cached under your user's home directory
+docker run --runtime nvidia --rm --network=host -v ~/ollama:/ollama -e OLLAMA_MODELS=/ollama dustynv/ollama:r36.2.0
+
+

Running either of these will start the local Ollama server as a daemon in the background. It will save the models it downloads under your mounted jetson-containers/data/models/ollama directory (or another directory that you override with OLLAMA_MODELS)

+

Ollama Client

+

Start the Ollama command-line chat client with your desired model (for example: llama3, phi3, mistral)

+
# if running inside the same container as launched above
+/bin/ollama run phi3
+
+# if launching a new container for the client in another terminal
+jetson-containers run $(autotag ollama) /bin/ollama run phi3
+
+

Or you can install Ollama's binaries for arm64 outside of container (without CUDA, which only the server needs)

+
# download the latest ollama release for arm64 into /bin
+sudo wget https://github.com/ollama/ollama/releases/download/$(git ls-remote --refs --sort="version:refname" --tags https://github.com/ollama/ollama | cut -d/ -f3- | sed 's/-rc.*//g' | tail -n1)/ollama-linux-arm64 -O /bin/ollama
+sudo chmod +x /bin/ollama
+
+# use the client like normal outside container
+/bin/ollama run phi3
+
+

Open WebUI

+

To run an Open WebUI server for client browsers to connect to, use the open-webui container:

+
docker run -it --rm --network=host --add-host=host.docker.internal:host-gateway ghcr.io/open-webui/open-webui:main
+
+

You can then navigate your browser to http://JETSON_IP:8080, and create a fake account to login (these credentials are only local)

+

+

Ollama uses llama.cpp for inference, which various API benchmarks and comparisons are provided for on the Llava page. It gets roughly half of peak performance versus the faster APIs like NanoLLM, but is generally considered fast enough for text chat.

Tutorial - Small Language Models (SLM)

+

Small Language Models (SLMs) represent a growing class of language models that have <7B parameters - for example StableLM, Phi-2, and Gemma-2B. Their smaller memory footprint and faster performance make them good candidates for deploying on Jetson Orin Nano. Some are very capable with abilities at a similar level as the larger models, having been trained on high-quality curated datasets.

+

+

This tutorial shows how to run optimized SLMs with quantization using the NanoLLM library and MLC/TVM backend. You can run these models through tools like text-generation-webui and llama.cpp as well, just not as fast - and since the focus of SLMs is reduced computational and memory requirements, here we'll use the most optimized path available. Those shown below have been profiled:

+

SLM Benchmarks

+ + + + +
+

•   The HuggingFace Open LLM Leaderboard is a collection of multitask benchmarks including reasoning & comprehension, math, coding, history, geography, ect.
+•   The model's memory footprint includes 4-bit weights and KV cache at full context length (factor in extra for process overhead, library code, ect)
+•   The Chat Model is the instruction-tuned variant for chatting with in the commands below, as opposed to the base completion model.

+
+

Based on user interactions, the recommended models to try are stabilityai/stablelm-zephyr-3b and princeton-nlp/Sheared-LLaMA-2.7B-ShareGPT, for having output quality on par with Llama-2-7B and well-optimized neural architectures. These models have also been used as the base for various fine-tunes (for example Nous-Capybara-3B-V1.9) and mini VLMs. Others may not be particularly coherent.

+

Chatting with SLMs

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 22GB for nano_llm container image
      • +
    • Space for models (>5GB)
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

The nano_llm.chat program will automatically download and quantize models from HuggingFace like those listed in the table above:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.chat --api=mlc \
+    --model princeton-nlp/Sheared-LLaMA-2.7B-ShareGPT
+
+
+

•   For models requiring authentication, use --env HUGGINGFACE_TOKEN=<YOUR-ACCESS-TOKEN>
+•   Press Ctrl+C twice in succession to exit (once will interrupt bot output)

+
+

This will enter into interactive mode where you chat back and forth using the keyboard (entering reset will clear the chat history)

+

+

Automated Prompts

+

During testing, you can specify prompts on the command-line that will run sequentially:

+
jetson-containers run $(autotag nano_llm) \
+  python3 -m nano_llm.chat --api=mlc \
+    --model stabilityai/stablelm-zephyr-3b \
+    --max-new-tokens 512 \
+    --prompt 'hi, how are you?' \
+    --prompt 'whats the square root of 900?' \
+    --prompt 'can I get a recipie for french onion soup?'
+
+

You can also load JSON files containing prompt sequences, like with --prompt /data/prompts/qa.json (the output of which is below)

+

Results

+ + +

•   The model responses are with 4-bit quantization, and are truncated to 256 tokens for brevity.
+•   These chat questions are from /data/prompts/qa.json (found in jetson-containers)

+ + + + + + + + + + + + + + + +

Tutorial - Stable Diffusion XL

+

Stable Diffusion XL is a newer ensemble pipeline consisting of a base model and refiner that results in significantly enhanced and detailed image generation capabilities. All told, SDXL 1.0 has 6.6 billion model parameters, in comparison to 0.98 billion for the original SD 1.5 model.

+

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices (SDXL requires >= ~13GB memory)

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x) +JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 6.8GB for container image
      • +
    • 12.4GB for SDXL models
      • +
    +
    4. +
  4. +

    Have followed the previous stable-diffusion-webui tutorial and have the webserver container running.

    +
    5. +
+
+

Downloading SDXL Models

+

Stable Diffusion XL is supported through AUTOMATIC1111's stable-diffusion-webui with some additional settings. First you need to download the SDXL models to your jetson-containers data directory (which is automatically mounted into the container)

+
# run these outside of container, and replace CONTAINERS_DIR with the path to the jetson-containers repo on your device
+CONTAINERS_DIR=/path/to/your/jetson-containers
+MODEL_DIR=$CONTAINERS_DIR/data/models/stable-diffusion/models/Stable-diffusion/
+
+sudo chown -R $USER $MODEL_DIR
+
+wget -P $MODEL_DIR https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors
+wget -P $MODEL_DIR https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0/resolve/main/sd_xl_refiner_1.0.safetensors
+
+
+

It's assumed that you already have the stable-diffusion-webui container and webserver running from the previous tutorial.

+
+

SDXL Settings

+

After the models have finished downloading, click the 🔄 button to refresh the model list in the web UI. Select sd_xl_base_1.0.safetensors from the Stable Diffusion checkpoint drop-down:

+

+

Then under the Generation tab, expand the Refiner section, and select sd_xl_refiner_1.0.safetensors from the drop-down:

+

+

Guidance on other relevant settings:

+
    +
  • Change the width/height to 1024x1024. SDXL works best at higher resolutions, and using 512x512 often results in more simplistic/cartoonish content. Changing image resolutions impacts the actual scene contents of the image, not just the details.
    • +
  • The refiner's Switch at setting dictates the step at which the refiner takes over from the base model. At this point, additional subject content will no longer be added to the scene, but rather its details further refined in the image.
    • +
  • Typical Sampling steps are between 20-40 and Switch at is between 0.7-0.9. This takes experimentation to find the best combination for the characteristics of your desired output.
    • +
  • Extensive negative prompts are not as necessary in the same way as SD 1.5 was (e.g. low quality, jpeg artifacts, blurry, ect)
    • +
  • CFG Scale controls how closely the model conforms to your prompt versus how creative it is.
    • +
+

When you get a good image, remember to save your random seed and settings so you can re-generate it later!

Setup a container for stable-diffusion-webui

+

The jetson-containers project provides pre-built Docker images for stable-diffusion-webui. You can clone the repo to use its utilities that will automatically pull/start the correct container for you, or you can do it manually.

+
git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
+
+

Info

+

JetsonHacks provides an informative walkthrough video on jetson-containers, showcasing the usage of both the stable-diffusion-webui and text-generation-webui. You can find the complete article with detailed instructions here.

+

+
+

How to start

+

Use jetson-containers run and autotag tools to automatically pull or build a compatible container image:

+
jetson-containers run $(autotag stable-diffusion-webui)
+
+

The container has a default run command (CMD) that will automatically start the webserver like this:

+
cd /opt/stable-diffusion-webui && python3 launch.py \
+  --data=/data/models/stable-diffusion \
+  --enable-insecure-extension-access \
+  --xformers \
+  --listen \
+  --port=7860
+
+

You should see it downloading the model checkpoint on the first run.

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)⚠️1

  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x) +JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 6.2GB for container image
      • +
    • Spaces for models
      • +
    +
    4. +
+
+

Set up a container for text-generation-webui

+

The jetson-containers project provides pre-built Docker images for text-generation-webui along with all of the loader API's built with CUDA enabled (llama.cpp, ExLlama, AutoGPTQ, Transformers, ect). You can clone the repo to use its utilities that will automatically pull/start the correct container for you, or you can do it manually.

+
git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
+
+

Info

+

JetsonHacks provides an informative walkthrough video on jetson-containers, showcasing the usage of both the stable-diffusion-webui and text-generation-webui. You can find the complete article with detailed instructions here.

+

+
+

How to start

+

Use jetson-containers run and autotag tools to automatically pull or build a compatible container image:

+
jetson-containers run $(autotag text-generation-webui)
+
+

The container has a default run command (CMD) that will automatically start the webserver like this:

+
cd /opt/text-generation-webui && python3 server.py \
+  --model-dir=/data/models/text-generation-webui \
+  --chat \
+  --listen
+
+

Open your browser and access http://<IP_ADDRESS>:7860.

+

Download a model on web UI

+

See the oobabooga documentation for instructions for downloading models - either from within the web UI, or using download-model.py

+
jetson-containers run --workdir=/opt/text-generation-webui $(./autotag text-generation-webui) /bin/bash -c \
+  'python3 download-model.py --output=/data/models/text-generation-webui TheBloke/Llama-2-7b-Chat-GPTQ'
+
+

From within the web UI, select Model tab and navigate to "Download model or LoRA" section.

+

You can find text generation models on Hugging Face Hub, then enter the Hugging Face username/model path (which you can have copied to your clipboard from the Hub). Then click the Download button.

+

GGUF models

+

The fastest oobabooga model loader to use is currently llama.cpp with 4-bit quantized GGUF models.

+

You can download a single model file for a particular quantization, like *.Q4_K_M.bin. Input the file name and hit Download button.

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+

+
+

Info

+

Model selection for Jetson Orin Nano

+

Jetson Orin Nano Developer Kit has only 8GB RAM for both CPU (system) and GPU, so you need to pick a model that fits in the RAM size - see the Model Size section below. The 7B models with 4-bit quantization are the ones to use on Jetson Orin Nano. Make sure you go through the RAM optimization steps before attempting to load such model on Jetson Orin Nano.

+
+

Load a model

+

After you have downloaded a model, click the 🔄 button to refresh your model list, and select the model you want to use.

+

For a GGUF model, remember to

+
    +
  • Set n-gpu-layers to 128
    • +
  • Set n_gqa to 8 if you using Llama-2-70B (on Jetson AGX Orin 64GB)
    • +
+

Then click the Load button.

+

Chat Template

+

If you're using a Llama model fine-tuned for chat, like the models listed above (except for LLaMA-30b), you need to use the oobabooga Instruct mode and set the template. On the Parameters tab, go to the Instruction Template sub-tab, then select Llama-v2 from the Instruction Template drop-down (or Vicuna, Guanaco, ect if you are using one of those models)

+
+

For the base text completion models (like LLaMA-30b), use the Default or Notebook tab.

+
+

Selecting the right chat template will make sure the model is being prompted correctly - you can also change the system prompt in the Context box to alter the agent's personality and behavior. There are a lot of other settings under the Generation tab, like the maximum length it should output per reply, and token sampling parameters like temperature and top_p for controlling randomness.

+

Then change back to the Chat tab, and under the mode section, make sure Instruct is selected (confusingly, not chat mode). Then you can start chatting with the LLM!

+

Results

+

+

Things to do with your LLM

+

Here are some common test prompts for coding, math, history ect. You can also ask it about geography, travel, nature, recipies, fixing things, general life advice, and practically everything else. Also Llama-2 is quite playful and likes to play games to test its logic abilities!

+
>> What games do you like to play?
+
+I'm a large language model, so I can play text-based games and answer questions on a wide variety of topics. Here are some game ideas:
+
+- 20 Questions:  You or I can think of an object, and the other player tries to guess what it is by asking up to 20 yes-or-no questions.  The goal is to guess the object in as few questions as possible.
+- Hangman: I can think of a word or phrase and you try to guess it by suggesting letters. Each incorrect guess will bring the hangman one step closer to being complete!
+- Word association: I'll give you a word and you have to come up with a word that is related to it. We can keep playing back and forth as long as you'd like!
+- Trivia: I can provide questions on a wide range of topics, from history to science to pop culture. See how many questions you can answer correctly!
+- Storytelling: I can start telling a story and then stop at a cliffhanger. You can then try to guess what happens next or even take over the storytelling and continue it in your own
+- Jokes: I love to tell jokes and make people laugh with my "Dad humor"!  Knock knock!  *giggles*

Let's run VoiceCraft, a Zero-Shot Speech Editing and Text-to-Speech in the Wild!

+
+

What you need

+
    +
  1. +

    One of the following Jetson devices:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    + JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 15.6 GB for voicecraft container image
      • +
    • Space for models
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

How to start

+

Use run.sh and autotag script to automatically pull or build a compatible container image.

+
jetson-containers run $(autotag voicecraft)
+
+

The container has a default run command (CMD) that will automatically start the Gradio app.

+

Open your browser and access http://<IP_ADDRESS>:7860.

+ + +

Gradio app

+

VoiceCraft repo comes with Gradio demo app.

+
    +
  1. Select which models you want to use, I recommend using 330M_TTSEnhanced on 32GB AGX Orin
    2. +
  2. Click load, if you run it for the first time, models are downloaded from huggingface, otherwise are loaded from /data folder, where are saved to from previous runs
    3. +
  3. Upload audio file of your choice (MP3/wav)
    4. +
  4. Click transcribe, it will use whisper to get transcription along with start/end time of each word spoken
    5. +
  5. Now you can edit the sentence, or use TTS. Click Run to generate output.
    6. +
+

+
+

Warning

+

For TTS it's okay to use only first few seconds of audio as prompt, since it consumes a lot of memory. On AGX 32GB Orin the maximal TTS length of generated audio is around ~16 seconds in headless mode.

+
+

jetson-containers also adds one convenient notebook (record-and-transcribe.ipynb) to record your audio sample on Jupyter notebook in order to run transcribe on your recorded audio.

+

+

record-and-transcribe.ipynb

+

This notebook is to let you record your own audio sample using your PC's microphone and apply Whisper's medium model to transcribe the audio sample.

+

It uses Jupyter notebook/lab's ipywebrtc extension to record an audio sample on your web browser.

+

+
+

Attention

+

When you click the ⏺ botton, your web browser may show a pop-up to ask you to allow it to use your microphone. Be sure to allow the access.

+

+
+Final check +

Once done, if you click on the "⚠ Not secure" part in the URL bar, you should see something like this.

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 10.9 GB for efficientvit container image
      • +
    • Space for checkpoints
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

How to start

+

Use the jetson-containers run and autotag commands to automatically pull or build a compatible container image.

+
jetson-containers run $(autotag efficientvit)
+
+

Usage of EfficientViT

+

The official EfficientViT repo shows the complete usage information: https://github.com/mit-han-lab/efficientvit#usage

+

Run example/benchmark

+

Inside the container, a small benchmark script benchmark.py is added under /opt/efficientvit directory by the jetson-container build process.

+

It is to test EfficientViT-L2-SAM in bounding box mode, so we can use this as an example and verify the output.

+

Download l2.pt model

+
mkdir -p /data/models/efficientvit/sam/
+cd /data/models/efficientvit/sam/
+wget https://huggingface.co/han-cai/efficientvit-sam/resolve/main/l2.pt
+
+
+

The downloaded checkpoint file is stored on the /data/ directory that is mounted from the Docker host.

+
+

Run benchmark script

+
cd /opt/efficientvit
+python3 ./benchmark.py
+
+

At the end you should see a summary like the following.

+
AVERAGE of 2 runs:
+  encoder --- 0.062 sec
+  latency --- 0.083 sec
+Memory consumption :  3419.68 MB
+
+

Check the output/result

+

The output image file (of the last inference result) is stored as /data/benchmarks/efficientvit_sam_demo.png.

+

It is stored under /data/ directory that is mounted from the Docker host.
+So you can go back to your host machine, and check jetson-containers/data/benchmark/ directory.

+

You should find the output like this.

Let's run NVIDIA's NanoSAM to check out the performance gain by distillation.

+

+
+

What you need

+
    +
  1. +

    One of the following Jetson:

    +

    Jetson AGX Orin (64GB) +Jetson AGX Orin (32GB) +Jetson Orin NX (16GB) +Jetson Orin Nano (8GB)

    +
    2. +
  2. +

    Running one of the following versions of JetPack:

    +

    JetPack 5 (L4T r35.x) +JetPack 6 (L4T r36.x)

    +
    3. +
  3. +

    Sufficient storage space (preferably with NVMe SSD).

    +
      +
    • 6.3GB for container image
      • +
    • Spaces for models
      • +
    +
    4. +
  4. +

    Clone and setup jetson-containers:

    +
    git clone https://github.com/dusty-nv/jetson-containers
+bash jetson-containers/install.sh
+
    +
    5. +
+
+

How to start

+

Use the jetson-containers run and autotag commands to automatically pull or build a compatible container image.

+
jetson-containers run $(autotag nanosam)
+
+

Run examples

+

Inside the container, you can move to /opt/nanosam directory, to go through all the examples demonstrated on the repo.

+
cd /opt/nanosam
+
+

To run the "Example 1 - Segment with bounding box":

+
python3 examples/basic_usage.py \
+    --image_encoder="data/resnet18_image_encoder.engine" \
+    --mask_decoder="data/mobile_sam_mask_decoder.engine"
+
+

The result is saved under /opt/nanosam/data/basic_usage_out.jpg.

+

To check on your host machine, you can copy that into /data directory of the container where that is mounted from the host.

+
cp data/basic_usage_out.jpg /data/
+
+

Then you can go to your host system, and find the file under jetson-containers/data/basic_usage_out.jpg

FileNotFoundError: [Errno 2] No such file or directory: './checkpoints/E2FGVI-HQ-CVPR22.pth'

+

You may find the TAM app fails to download a checkpoint file E2FGVI-HQ-CVPR22.pth.

+
Downloading checkpoints from Google Drive... tips: If you cannot see the progress bar, please try to download it manuall               and put it in the checkpointes directory. E2FGVI-HQ-CVPR22.pth: https://github.com/MCG-NKU/E2FGVI(E2FGVI-HQ model)
+Access denied with the following error:
+
+        Cannot retrieve the public link of the file. You may need to change
+        the permission to 'Anyone with the link', or have had many accesses. 
+
+You may still be able to access the file from the browser:
+
+         https://drive.google.com/uc?id=10wGdKSUOie0XmCr8SQ2A2FeDe-mfn5w3 
+
+

You can manually download the checkpoint file on your Docker host machine.

+
cd jetson-containers/
+pip install gdown
+source ~/.profile
+gdown https://drive.google.com/uc?id=10wGdKSUOie0XmCr8SQ2A2FeDe-mfn5w3 
+mv E2FGVI-HQ-CVPR22.pth ./data/models/tam/
