Ok, this is quite strange. When you say it hangs, what do you mean, there is no error, it is just stuck like in an infinite loop? First two things...

Alright, I think I see where the problem comes from. If there is no representant on a class in the data, them the while loop: https://github.com/HuguesTHOMAS/KPConv-PyTorch/blob/7fdbc57f9b56b6139865ae89c3a69d62c61449b3/datasets/SemanticKitti.py#L772-L774 is infinite because class_indices.shape[0]...

Hi @chaitjo, Yesterday I pushed several corrections, including this one, but also for bugs that occur in S3DIS.

Hi @tiger-bug, Actually it is not that easy to do. With a few simple modifications to the current implementation, you can restart a new training with weights from a given...

This error is raised here: https://github.com/HuguesTHOMAS/KPConv-PyTorch/blob/3a774ff8d54a4d080fe65093b2299ede35d9735d/datasets/S3DIS.py#L344-L348 And only appear if the code encountered an input sphere with less than 2 points in it (so with only 1 or 0 point),...

To create a batch, the loop goes like this: ``` Repeat until total number of point in batch > batch_limit: 1. sample a point from the dataset 2. find all...

Are you using S3DIS or your own dataset?

Oh ok, I did not understand. I thought you were using your own dataset. In that case, there might be a problem with the dataset. I would suggest trying to...

Could you share the **.ply** files in your `input_0.040 folder`? It is where the spheres come from: - Area_1.ply - Area_2.ply - Area_3.ply - Area_4.ply - Area_5.ply - Area_6.ply And...

`_ proj.pkl` is for testing purposes. And Area_5 is the test area. I honestly have no idea why your code is doing this. At this point I see only two...
