[Tutorial] Install Stable Diffusion on AMD GPU (AUTOMATIC1111)

Windows+AMD support has not officially been made for webui,
but you can install lshqqytiger's fork of webui that uses Direct-ml.

-Training currently doesn't work, yet a variety of features/extensions do, such as LoRAs and controlnet. Report issues at https://github.com/lshqqytiger/stable-diffusion-webui-directml/issues

1. Install Python 3.10.6 (ticking Add to PATH), and git
2. paste this line in cmd/terminal: git clone https://github.com/lshqqytiger/stable-diffusion-webui-directml && cd stable-diffusion-webui-directml && git submodule init && git submodule update
   ^{(you can move the program folder somewhere else.)}
3. Double-click webui-user.bat
4. If it looks like it is stuck when installing or running, press enter in the terminal and it should continue.

If you have 4-6gb vram, try adding these flags to `webui-user.bat` like so:

• COMMANDLINE_ARGS=--opt-sub-quad-attention --lowvram --disable-nan-check
• You can add --autolaunch to auto open the url for you.

(The rest below are installation guides for linux with rocm.)
