Potentially related:

• Linux Conda Xformers Install Issue #38
• Xformer performance decrease #23

[0xdevalias]

Are you following the xformers installatiomn instructions from here?

• https://github.com/facebookresearch/xformers#installing-xformers

pip wheels: There is no updated package available on pip, please install from conda or from source

This is probably more an issue you should raise on the xformers repo, as it seems to be unrelated to SDv2 itself?

I have met a similar error. However, I solved by installing Microsoft Visual C++ 14.0 or greater.
