Conda install PyTorch might cause a failure to build pointops

[mbendjilali]

Hello,
As of today, the conda install of PyTorch is dynamically linked to an old version of MKL, which does not contain the symbol iJIT_NotifyEvent, leading to a crash when launching the libs/pointops/setup.py script.
To alleviate this issue, I recommend following this topic solution, i.e. using pip install for PyTorch, as it is statically linked to MKL.
pip3 install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html
