code of knowledge distillation in the paper

Thanks for sharing the paper. I am very interested in it and doing relative research.

I notice you mentioned knowledge distillation in the paper and it was used to improve the voxel-based 3D CNN and point-based architectures. I think this observation is exciting and I want to try it for my ideas. I have reproduced the classification experiments using your codebase.

But in this repo, the code of knowledge distillation is absent. I understand that many years have passed since you conducted the experiments. Can you try to find this part of code, or provide me some references/github repositories/advice to faciliatate my re-implentations?

It would be appreciated.
