Cannot install fschat[model-worker,webui]

"Hello;

I'm getting an error while trying to run it on Windows 11. Can you help?"

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

The report names the fschat[model-worker,webui] extras and a torch resolution failure on Windows 11; start by reproducing that pip installation and inspecting the published dependency metadata. Done means the installation resolves successfully on Windows 11 or the issue documents the precise unsupported constraint and workaround.
