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"Python 3.10.6 (tags/v3.10.6:9c7b4bd, Aug 1 2022, 21:53:49) [MSC v.1932 64 bit (AMD64)]Commit hash: 67d011bTraceback (most recent call last):File "C:/Users/giray/stable-diffusion-webui/launch.py", line 110, inrun_python("import torch; assert torch.cuda.is_available(), 'Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check'")File "C:/Users/giray/stable-diffusion-webui/launch.py", line 60, in run_pythonreturn run(f'"{python}" -c "{code}"', desc, errdesc)File "C:/Users/giray/stable-diffusion-webui/launch.py", line 54, in runraise RuntimeError(message)RuntimeError: Error running command.Command: "C:/Users/giray/stable-diffusion-webui/venv/Scripts/python.exe" -c "import torch; assert torch.cuda.is_available(), 'Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check'"Error code: 1stdout:stderr: Traceback (most recent call last):File "", line 1, inAssertionError: Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check

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：

COMMANDLINE_ARGS=
and change it to:
COMMANDLINE_ARGS= --lowvram --precision full --no-half --skip-torch-cuda-test

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。
