"RuntimeError: Unsupported image type, must be 8bit gray or RGB image" on Surface Laptop 3 IR Camera

[JoshAtticus]

Please describe the issue in as much detail as possible, including any errors and traces.
If your issue is a camera issue, be sure to also post the image generated by running sudo howdy snapshot.

When adding a face model with /dev/video2 (IR Camera on Surface Laptop 3) I get the following error

josh@BigSurface:~$ sudo howdy add
Adding face model for the user josh
Enter a label for this new model [Initial model] (max 24 characters): josh

Please look straight into the camera
Traceback (most recent call last):
  File "/usr/local/bin/howdy", line 95, in <module>
    import cli.add
  File "/usr/lib/security/howdy/cli/add.py", line 157, in <module>
    face_locations = face_detector(gsframe, 1)
RuntimeError: Unsupported image type, must be 8bit gray or RGB image.

Here is sudo howdy snapshot output

And here is the output of v4l2's list formats thing

josh@BigSurface:~$ v4l2-ctl --list-formats -d /dev/video2
ioctl: VIDIOC_ENUM_FMT
	Type: Video Capture

	[0]: 'GREY' (8-bit Greyscale)

System's numpy >= 2.0.0 may cause this error. If your systems' numpy is >= 2.0.0, would you like to downgrade it to 1.26.4 (latest version of 1.x). At least this fixed this error in my 2 laptops running Garuda linux.

Thank you! I will test this later

It worked! Thank you so much!

This Workaround doesn't fixed it for me.

Did you downgrade with pip as sudo? Are you also using a Surface Laptop 3?

I'm using a Surface Pro 7 with external Logitech Cam. But your question "...Did you downgrade with pip as sudo?..." was the right hint - now it works!
Thanks

No problem, yeah you can keep the user installation of numpy up to date just the system one needs to be downgraded

[jim-davenport]

Would you please post the steps to downgrade numpy? Thanks!

That would be helpful indeed....

sudo pip install --upgrade numpy==1.26.4
