Dear all,
I am experiencing a strange behavior of the dataloader  when I import some custom modules at the beginning of my training script. After the custom scripts are loaded and  when the training starts (or after few iterations) i encounter: "RuntimeError: DataLoader worker (pid 7326) is killed by signal: Floating point exception. " when the worker tries to get the new batch.
If I don’t import everything runs fine, if I set num workers = 0, the network trains but extremely slowly.
I have spent quite a lot of time trying to import my custom modules differently (at the beginning I was doing sys.append, but now I have changed everything to “import folder.subfolder.script_name”, which seems more correct. However this does not solve the problem.
It is very hard to debug for me, could you give me some hints? @ptrblck or @albanD ?
Kind Regards,
Stefano
