前段时间这个novelAI数据集泻露开源了之后，网上就流出了一堆AI作品，看着还不错，再一看任务管理器，这12GB显存空荡荡，就大抵想装个玩玩。
本文负责踩坑，安装可参照官方文档
https://github.com/AUTOMATIC1111/stable-diffusion-webui
or

1.github.com无法访问
大抵是受“长城”（你懂的）和国际带宽的影响，国内github经常出现无法访问的情况，要正常访问，可以使用V( )( )或watttoolkit，或者直接使用国内镜像（kgithub.com）（这个方法我们后续也会用到）。
附：国内镜像使用方法：将网址内的github.com统一替换成kgithub.com
如：https://github.com/AUTOMATIC1111/stable-diffusion-webui ==》 https://kgithub.com/AUTOMATIC1111/stable-diffusion-webui
2.Installing torch and torchvision报错
安装torch的时候碰到：
stderr: ERROR: Could not find a version that satisfies the requirement torch==1.12.1+cu113
emmm，这个只能说大概率重装一下python会解决（因为我就是这么解决的）。当然，建议这些东西都在像anaconda这种python虚拟环境中配置，并且还可以省去配置git的烦恼

3.Installing gfpgan报错
像这样：
Installing gfpgan
Traceback (most recent call last):
File "E:\ai\stable-diffusion-webui\launch.py", line 122, in <module>
run_pip(f"install {gfpgan_package}", "gfpgan")

不用想，又是国内github连不上
这位老哥提供了一个思路（https://blog.csdn.net/Tjzlo/article/details/127309267）：修改stable-diffusion-webui-master文件夹中的launch.py
最好用python编辑器打开，没有的话直接用记事本打开编辑
记事本按下ctrl+F使用搜索功能，上面就会有一个对话框，输入github.com搜索，并将里面所有的github.com替换为kgithub.com(或者一个国内能用的镜像or加速网址)
CTRL+shift可呼出搜索（查找）框
替换github.com---->kgithub.com
保存，重新运行webui-user.bat
解决！！！
4.至于模型的安装与下载
https://www.tjsky.net/tutorial/457中也有提到，当然，B站的up们也提供了许多很好的模型，https://www.bilibili.com/video/BV1dR4y1D7bK/?share_source=copy_web&vd_source=6ce7ac306ec9c4efdf15cfcb26ab1abe
up：小李xiaolxl 提供的模型（注：链接在他视频的评论区）
教程大同小异，Windows端模型安装建议走https://www.tjsky.net/tutorial/457中的教程
End.
祝大家玩得愉快
