OSError: [WinError 193]

Good day to you,

I am using Automatic1111, but today decided to switch to ComfyUI once more, but I get the following error when starting "run_nvidia_gpu" (I do own such a card):

Any idea? I installed the following, but to no avail: pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu121 pip install -r requirements.txt

I use Windows 11 64bit and a Nvidia Geforce 3060 12GB.

What can I do?

The Windows pre-packaged versions already include torch and all of comfy's own dependencies (you didn't specify which one of the comfy packages you downloaded) but it's unlikely running pip like that actually installed torch where you expected it to. It needs to be in the embedded environment. You also need to have a minimum driver version to run the various versions of cuda: >=527.41 in the case of 12.1, or just install the 11.8 version which doesn't have as many libraries you'll need to build yourself when extensions need them; the newness of torch 2.1.0 + 12.1 means some of the packages don't exist yet as prebuilts and building them ranges from easy to completely broken at the moment.

SUCCES! I installed the mentioned "Cuda 11.8" dev package.

While the "ComfyUI_windows_portable_nvidia_cu121_or_cpu" (resulting in the error described above) still didn't work, another package named "ComfyUI_windows_portable_nvidia_cu118_or_cpu" DID WORK.

Thanks for the support!

Glad it helped. Happy image-generating
