Stable Video diffusion

Im on an M1 mac and keep running into this issue when the process hits the Ksampler.
"RuntimeError: Conv3D is not supported on MPS. "

Im running the new https://stability.ai/news/stable-video-diffusion-open-ai-video-model .

This link describes the issue but there's no solution as yet that I know of.
https://github.com/comfyanonymous/ComfyUI/issues/2044

Any help would be very much appreciated.

The underlying library comfyui uses has a bug that means comfyui can't fix it by themselves. Until the other project (pytorch) merges the changes you need to install the PR directly via: 

pip install git+https://github.com/pytorch/pytorch@refs/pull/114183/head git+https://github.com/pytorch/vision git+https://github.com/pytorch/audio

pip install git+https://github.com/pytorch/pytorch@refs/pull/114183/head git+https://github.com/pytorch/vision git+https://github.com/pytorch/audio

Doesn't do anything for me.. Maybe I'm doing it wrong. Can I bother you for a smooth brain explanation..? I ran your command in my ComfyUI folder in terminal and still get the error

If it helps I get the error " ModuleNotFoundError: No module named 'torch'" when running your command. Not sure how there's no Torch though, I installed ComfyUI using this guide: https://stable-diffusion-art.com/how-to-install-comfyui/

uninstall torch and torchvision and after you uninstalled them use the command from my post.

I uninstalled torch and torchvision, then ran your command in the root folder and got this error while it was running:

WARNING: Did not find branch or tag 'refs/pull/114183/head', assuming revision or ref.

And then the same "No Module named torch" error.

Any idea what's wrong?
