xformers not working [BUG REPORT]

[dangerweenie]

Getting this error after installing on Windows 11;

| WARNING | xformers | WARNING[XFORMERS]: xFormers can't load C++/CUDA extensions. xFormers was built for:
    PyTorch 2.1.0+cu121 with CUDA 1201 (you have 2.1.0+cu118)

This is just a warning: triton is not available

using xfomers in other venvs (comfyUI, automatic1111, etc), no issues.

seems the xformers this install wants to use requires a newer vision of xformers, but i know if i try to install that there will probably be a load of other dependencies that need to ne upgraded.

anyone using this without xformers? is it recommended?

Xformers shouldn't really affect performance or memory usage drastically for most models. But from the error it looks like you installed xformers for python 3.10.11 while you're on 3.10.10, so it's suggested you re-install xformers for the right version. (Or simply use audio-webui without xformers)
