Suggest a potential alternative/fix

conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia

I was able to use this command to succesfully install the cuda related packages

Since I am not very familiar with the python env, please let me know if I should open a PR to resolve this issue.
