On windows you must use pip to install mmcv-full

[ultimatech-cn]

When I use
mim install mmcv-full==1.7.0

I always got following error
RuntimeError: nms_impl: implementation for device cuda:0 not found.

I thought it was cuda version problem and try to downgrade my cuda from 12.2 to 11.8.

Finally when I use

mim uninstall mmcv-full
pip install mmcv-full

The building process will take twenty minutes. When I restart app, the error is gone.

thanks for the report.

we supsect you may have a mmcv (the regular non-full version) installed before, so the safe solution could be:

mim uninstall mmcv mim uninstall mmcv-full pip install mmcv-full

anyway, it is great to know that now it is working for you on Windows!
