Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

I have not downloaded the requirement "xformers"
It always failed, showing that:
"note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for xformers
Running setup.py clean for xformers
Failed to build xformers
ERROR: Failed to build installable wheels for some pyproject.toml based projects (xformers)"

There are some errors:

Steps to reproduce the problem

cd '/Users/ycy/Desktop/ . . . /stable-diffusion-webui'

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zshrc
source ~/.zshrc

arch -arm64 brew install cmake protobuf rust python@3.10 git wget

chmod +x webui.sh
./webui.sh

Then it shows the error that there is no requirement "xformers" though the webui can be opened

I have tried to install it by the code "pip install xformers", but it did not work.

What should have happened?

I think it would be completely succeeded. The "xformers" would be fine.

What browsers do you use to access the UI ?

No response

This pops up every couple of years there is a way its a little difficult to do and can break stuff so read , reread , read a third time take a break read some more times. I jacked it once had to factory reset my pro, however I did get it to work afterwards
