Error while running 'pip install ./pointnet2_ops_lib/'

[zhengqianisme]

Hello,
I am trying to do the setup for using Treepartnet. My environment contains Python = 3.7.13 , cuda=11.5 and pytorch=1.5.0. If I try running "pip install -r requirements.txt" I receive the following errors during the compiling:

You may need to install nvcc corresponding to your runtime pytorch version.
