Install fails on Mac because Mac doesn't support xformers

[tchrischan]

Including this comment from closed issue #82:

@krummrey ,
I am trying to get this working on the Mac via pip install -r requirements.txt
I tried to match your March 14 version just so we are on the same baseline
I am using python 3.12

Can you help. Not sure why it says torch module not found when it clearly was installed

(venvtaggui) anand@Anands-MacBook-Pro taggui % pip install torch

Use Python 3.11 or 3.10.

[tchrischan]

Two problems with installing on Mac (x64): bitsandbytes max version is 0.42.0, but more importantly, the error above is caused because xformers isn't supported on Macs.

Commenting it out in requirements.txt or, more eloquently:
xformers==0.0.25.post1; platform_system == "Linux" or platform_system == "Windows"

I'd push a PR but I'm not allowed. I am on Python 3.12.

Why are you not allowed?

I am on Python 3.12.

Use Python 3.11 or 3.10.
