安装流程：

1. 下载stable-diffusion源码

   <https://github.com/AUTOMATIC1111/stable-diffusion-webui/releases/tag/v1.2.1>
   

2. 安装python

   <https://www.python.org/ftp/python/3.10.6/python-3.10.6-amd64.exe>
   

3. 添加host

   1. 打开C:\Windows\System32\drivers\etc\host

   2. 添加

      199.232.69.194 github.global-ssl.fastly.net
      140.82.112.3 github.com
      

4. 修改launch.py

   将所有
   <https://github.com>
   替换成
   <https://ghproxy.com/https://github.com>
   

5. 运行stable-diffusion-webui-1.2.1目录下webui-user.bat

   安装时长较长，耐心等待

6. 安装成功日志，主要是出现了地址“http://127.0.0.1:7860”

注意事项

1. python版本要为3.10.6版本，不然会出现奇怪报错
2. 主要解决的问题就是github下载一些开源工程会超时，只要按照教程修改host和lanch.py就能解决
