Proxy error while installing Stable Diffusion locally

I am installing Stable Diffusion on a local PC, Windows 10, Python 3.10.6.
While running the webui-user.bat, I meet the error:

urllib3.exceptions.ProxySchemeUnknown: Proxy URL had no scheme, should start with http:// or https://

I don't know where to set the Proxy. Can anyone help?

Solution

You can set the proxy from the command line in Windows with:

set http_proxy=http://username:password@proxy.example.com:8080 
set https_proxy=http://username:password@proxy.example.com:8080

Note: If your proxy uses the http scheme, then https_proxy should also use http, not https.
