error: [WinError 5] Access is denied

[knuthnads]

Trying to install nerfacc in a python virtual environment. For some reason this is failing with '[WinError 5] Access is denied'. Fails to install even if I run cmd with administrator.

CUDA 11.8
Windows 10
pytorch 2.3.0

Install command:

pip install git+https://github.com/KAIR-BAIR/nerfacc.git@v0.5.2
