Operating System

Windows 11

DeepLabCut version

3.0.0rc9 with Python 3.10.18

What engine are you using?

pytorch

DeepLabCut mode

multi animal

Device type

AMD Ryzen 7 5700U (Integrated GPU only)

Bug description 🐛

I get an error when trying to run python -m deeplabcut. Previously I've also encountered this error when doing import deeplabcut.pose_estimation_pytorch as dlc_torch, however, that one was fixed after reinstalling the environment from the yaml file directly. I'm unsure while it still happens for python -m deeplabcut as I've validated my installation multiple times now.

Steps To Reproduce

1. Install conda environment with .yaml file
2. Activate conda environment
3. Run python -m deeplabcut
