解决在Windows安装stable diffusion遇到“Torch is not able to use GPU”的问题

遇到的问题

在windows上安装stable diffusion的最后一步执行webui-user.bat时，提示了错误信息assertionerror: torch is not able to use gpu; add --skip-torch-cuda-test to commandline_args variable to disable this check

具体错误代码如下：

venv "c:\users\giray\stable-diffusion-webui\venv\scripts\python.exe"

解决方法

参考了github上的issue，需要修改webui-user.bat文件，具体更改如下：

保存修改之后再次运行webui-user.bat就可以了。如果这个解决方法还没解决问题，可以查看同个issue下的其它回答，或者能找到解决方法。
