Expected behavior

Installing ESP-PPQ following the "pip install git+https://github.com/espressif/esp-ppq.git" instructions makes it possible to quantize my model using quantize_custom_torch_model.py (albeit providing my own model instead of mobilenet etc.).

Actual behavior (suspected bug)

ESP-PPQ depends on older versions of torch that ends up conflicting with torchvision.

Error logs or terminal output

You can end up in several situations, but this seems most relevant, as old torch (2.2.2) is forced:

  File "...\Projects\esp-dl\tools\quantization\quantize_custom_torch_model.py", line 6, in <module>
    import torchvision
  File "...\Projects\esp-dl\.venv\Lib\site-packages\torchvision\__init__.py", line 10, in <module>
    from torchvision import _meta_registrations, datasets, io, models, ops, transforms, utils  # usort:skip
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "...\Projects\esp-dl\.venv\Lib\site-packages\torchvision\_meta_registrations.py", line 163, in <module>
    @torch.library.register_fake("torchvision::nms")
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'torch.library' has no attribute 'register_fake'

Steps to reproduce the behavior

• Follow the esp-ppq installation on esp-dl
• Quantize a model.

Please install torch>=2.4.0 first and then reinstall esp-ppq.

Thank you, but I am afraid that esp-ppq causes torch 2.2.2 to reinstall and then it fails again.
However, upgrading Torch and then leave esp-ppq untouched as is, works.
I suppose this must imply that threre is a problem with dependencies?

Hi @nicklasb,
Thanks for your feedback, which version is your python? I will check it.
