Torch failed to install

[Revenn555]

I can't complete the installation due to errors:

"fatal: not a git repository (or any of the parent directories): .git

How to fix this?

PS I tried manually installing PyTorch using
conda install pytorch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 pytorch-cuda=12.1 -c pytorch -c nvidia

But it took up a ton of disk space and didn't help, and now I don't know how to remove it.

Torch 2.1.2 does not support Python 3.13. Install 3.10.6 or use reForge instead of the original webui.
