RuntimeError: Expected isFloatingType(grads[i].type().scalarType()) to be true, but got false about h3dnet

This is rarely hard to parse. It might be something wrong with the environment. Have you tried to train any other well-known models? For example, my codebase is built on this repo. Can you try it first? It's more easier to debug since it's simpler and lots of people have been using it.

It depends. Sampling and grouping are done in C++. For architecture changes, you can look into the pointnet2_modules.py file.

Feel free to reopen if you have follow up questions.

@zaiweizhang : thank you very much for your suggestion, I will try with Votenet first.

@zaiweizhang : I uninstall pytorch==1.4.0 and install pytorch==1.2.0, then the bug disappear :) . Environment from PointNet++ to VoteNet, to H3DNet is very difficult to customize due to extend library of pointnet write by C++ , I think ?
