Minimum PyTorch Version?

[fishBone000]

Hello! I want to use stable diffusion webui on an old computer, with old Nvidia graphic card (compute capability 3.0, CUDA 10.2) which new PyTorch versions don't support.
There exist guides on compiling PyTorch for such devices, and there's a built PyTorch 1.8 for compute capability 3.0.

However when running the webui.sh, I can see it's trying to install PyTorch 1.12 (or 2.0/2.1? couldn't remember).
So can I run it with PyTorch 1.8? If not what's the minimum PyTorch version required? I can try tweaking the build script for versions <= 1.13, but it seem hard to tweak for versions >= 2.0 as there's even no build functions / options for CUDA 10.2 in the build scripts.

Thanks

Set the TORCH_COMMAND variable in webui-user.sh to the version you want. Old versions can be found here.

If torch has already been installed, add --reinstall-torch to COMMANDLINE_ARGS (remove it afterward) or delete the venv folder.

However, it probably won't run well, if at all, on a card that old. You can try the --lowvram option, but you may have to run it on the CPU instead.
