Xformers library is an optional way to speedup your image generation.

If you use a Pascal, Turing, Ampere, Lovelace or Hopper card with Python 3.10, you shouldn't need to build manually. Just launch the repo with `--xformers`. A compatible wheel will be installed.
1. go to the webui directory
2. `source ./venv/bin/activate`
3. `cd repositories`
3. `git clone https://github.com/facebookresearch/xformers.git`
4. `cd xformers`
5. `git submodule update --init --recursive`
6. `pip install -r requirements.txt`
7. `pip install -e .`
