Problem when instaling with pip

[tammy3107]

when I try to run the command :

pip3 install -U MinkowskiEngine

I get this error:-

    `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
    of the deprecation of `distutils` itself. It will be removed for
    Python >= 3.12. For older Python versions it will remain present.
    It is recommended to use `setuptools < 60.0` for those Python versions.

Try to install cuda in conda (choose the right cuda version).

conda install cuda -c nvidia/label/cuda-11.3.0

nvcc --version # validate

see: https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#conda-installation
