ComfyUI update

[seung-ltd]

ComfyUI no longer starts after recent update.

OSERROR: [WinError 126] The specified module could not be found. Error loading "...fbgemm.dll" or one of its dependencies.

same error

Assuming nvidia GPU, try going to the Packages tab -> 3 dots menu for comfy -> Python Packages -> + Button and enter
torch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 xformers==0.0.23.post1 --extra-index-url https://download.pytorch.org/whl/cu121 --force-reinstall

This will reinstall torch & should include the missing file as well

this does fix the install but breaks most of my custom nodes, had previously tried reinstalling torch & ran into similar issues, will go through and try to fix the errors preventing them from importing

[seung-ltd]

Would reverting the comfy ui install to a previous build fix this? Everything was stable before. If so, how do I go about reverting it?

[shamanicvocalarts]

after reinstalling a few problematic custom nodes it seems the fix posted above fixes the issue.

with regards to @seung-ltd question about reverting the build, I believe there is no way to do this inside of the stability-matrix client, though there may be a way to do so via Pip/git.

I wonder if having a native way to revert / install older builds directly from inside of stability matrix would be a valuable feature request. it could be worth making a feature request for this

Tried @mohnjiles method, but it causes a numpy-error("Numpy is not available", in KSampler) instead and when the ComfyUI is updated the original error returns.

Have tried uninstalling and reinstalling ComfyUI via StabilityMatrix, but error remains,

This fixed the issue for me thanks

I'm getting this too, I'm trying to use the AutoCinemagraph ComfyUI workflow and I'm getting these same errors

Is there a way to have a later version of pytorch to be installed this way that is newer than 2.1.2?

for me it was resolved that I installed the Visual C++ Redistributable Runtimes All-in-One
