Just some suggestions about setting up the environment

Just a kind reminder for anyone experiencing similar difficulties setting up the environment:

1. I highly recommend installing Python version 3.8 or higher on a Linux machine.
2. Many problems can arise with PyTorch3D, especially when installing a new version of PyTorch. The original command "conda install pytorch3d -c pytorch3d" only works for "torch < 1.6." For newer versions of PyTorch, I recommend installing PyTorch3D manually from the GitHub repository.
3. When installing Kaolin, it is crucial to keep your CUDA toolkit consistent with the Kaolin version. I recommend using the command "pip install kaolin==0.13.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-{your torch version, for example: 1.10.0}_cu{your cuda toolkit version, for example: 111}.html". Using the wrong version can cause a lot of problems.
4. To avoid potential conflicts, I highly recommend creating a virtual environment with Conda for this project.
