roop has nothing in the extension tab

I have just loaded forge and selected the extensions I want, and roop has a tab but nothing inside it. Here is what my script says

ERROR facechain: failed to install mmcv, make sure to have "CUDA Toolkit" and "Build Tools for Visual Studio" installed

Start with webui/extensions/sd-webui-roop/install.py and reproduce the extension installation on the reported Windows setup. Capture the complete traceback beyond the truncated output and compare it with the required CUDA Toolkit, Visual Studio Build Tools, and listed extension requirements. Done means roop installs without install.py failing and its extension tab contains its expected controls.
