首先python版本要求：
Python3.10
第一步
下载框架代码：https://github.com/AUTOMATIC1111/stable-diffusion-webui.git
github慢的话把域名换成https://kgithub.com/
第二步
双击执行webui.bat，执行过程中会安装一些软件包，主要在launch.py中，有些比较慢，你可以换换git地址，我得launch.py
# this scripts installs necessary requirements and launches main program in webui.py

另外，要跑起来还需要显卡驱动程序更新：
Windows下，在这里下载安装：https://developer.download.nvidia.cn/compute/cuda/11.7.1/local_installers/cuda_11.7.1_516.94_windows.exe
有些模块启用起来要忽略一下，根据报错处理，我的webui-user.bat如下：
@echo off set PYTHON= set GIT= set VENV_DIR= set COMMANDLINE_ARGS= --xformers --no-half --disable-nan-check --skip-torch-cuda-test --precision full call webui.bat
最终跑起来了，先使用txt2img生成一张图（哈利波特暴打伏地魔），如下：
img2img怪怪的：
另外，你可以安装很多模型，模型在这里下载：
https://civitai.com/
下载下来的模板放在这个目录：stable-diffusion-webui\models\Stable-diffusion
看这情况以后你在网上看到的很多图片和视频中的人，建筑，风景都不一定是真实的而是ai生成的。
