Any suggestions for what to reinstall/setup properly to get rid of this problem?

I've tried reinstalling Visual C++ redist according to this thread:

pip install torch==2.2.0 --user
and then kill and reopen the terminal

Which version of CUDA is needed for this?

I have gotten rid of the fbgemm.dll error (seems to have been a W11 VSC++ driver error).

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
torchvision 0.19.0 requires torch==2.4.0, but you have torch 2.2.0 which is incompatible.
xformers 0.0.27.post2 requires torch==2.4.0, but you have torch 2.2.0 which is incompatible.

How to solve fbgemm.dll error?

Get Visual Studio Installer, and then modify the installation. I think it was under Desktop development with C++, and get the latest MSVC. v143 is the one I have now.
