Xformers incompatible with auto-installed torch and python versions

[steveernst117]

I seem to have solved part of the problem by replacing everything in the 'xformers' folder with the contents of the folder of the same name after downloading the zip file of this version here: https://github.com/facebookresearch/xformers/releases/tag/v0.0.24

Doing so enabled me to do inpainting tasks without problems. However, when trying img2img I get this error:

• It was not possible to generate your image!

• Error: No operator found for memory_efficient_attention_forward with inputs:
  query : shape=(1, 2, 1, 40) (torch.float32)

I think it may be related to this other error that comes up first:
WARNING[XFORMERS]: Need to compile C++ extensions to use all xFormers features.
Please install xformers properly (see https://github.com/facebookresearch/xformers#installing-xformers)
Memory-efficient attention, SwiGLU, sparse and more won't be available.
Set XFORMERS_MORE_DETAILS=1 for more details

txt2img works fine.
