[Stable Diffusion] Windows 部署 Stable Diffusion WebUI 的坑

1.RuntimeError: Couldn't install gfpgan.

运行 webui.bat 时的报错如下：

Installing gfpgan

  See above for output.

  note: This error originates from a subprocess, and is likely not a problem with pip.

解决方法：

根据 stackoverflow.com/questions/7…

在 venv/Lib/site-packages 中打开 cmd 然后执行 pip install package_name -t .

RuntimeError: Couldn't install gfpgan. 或 RuntimeError: Couldn't install clip. 同理

特殊的是，对于 open_clip，名字实际上是 open_clip_torch，所以应该执行 pip install open_clip_torch -t .

2.换线路或重复运行 webui.bat

clone 失败主要是跟 git 命令内部的什么操作有关……我也不懂

所以只能寄希望于这种玄学了

有的时候还真的有用
