It seems like the pip install . isn't working as expected. After a successful install I'm not able to import m2t2 from outside the repo.

Steps to reproduce

1. cd $M2T2_DIR
2. micromamba env create -n m2t2 python=3.10
3. micromamba activate m2t2
4. micromamba install cuda -c nvidia/label/cuda-11.8.0
5. pip install torch==2.0.1 torchvision==0.15.2
6. pip install pointnet2_ops/
7. pip install -r requirements.txt
8. pip install .
9. cd $HOME
