Mulitprocessing errors in pre-processing?

[rkube]

Hi,
I'm trying to pre-process the FRNN dataset on traverse and get these errors when running guarantee_preprocessed.py. Does anyone know what the cause of this may be?

I've replaced pathos with https://docs.python.org/3/library/multiprocessing.html and I'm getting the same errors.
