A Pytorch Implementation of “Modeling Local Geometric Structure of 3D Point Clouds using Geo-CNN”

geo-cnn-pytorch-pyg's Issues

GPU problem

• you run the codes on a single gpu or multi gpu? some differences exist in the code? thanks!

question about the data?

could you please tell me what the meaning of "pos, norm, batch = data.pos, data.norm, data.batch" is ?
what 's the shape of pos,nor and batch? i can figure out the pos means the position, the norm is the normal data, what about batch?

Support Document

Hi,
Great work!!
I am trying to understand the code but I have some doubts.
Can you share a support document for this implementation in case you have it.
Thank you!

A question about "id_euc = knn(pos.view(B, N, -1), 16)" in geocnn.py

When I run the code, I got this error, how can I fix this？
