Can you help me?

Such an error without aby message should be coming from one of the c++ wrappers, but it is not entirely sure.

I could help you more if you could track down when the error happens. First remove the multithreaded input pipeline buy setting the input_threads = 0 in the config. https://github.com/HuguesTHOMAS/KPConv/blob/16bfbb96ac9af48a3c829d1f8123152d35b63862/training_S3DIS.py#L64-L65 Then try to follow the execution of the code by running it in debug mode, or by placing print() statements along the code.

When you get which line in the code returns this error, I should be able to help solving this
