I would appreciate your minimum reproducing example.
Thanks

I can provide a dataset and code through PM if you're unable to replicate.
Very, very rarely (maybe 1:20 or 1:50) this error dumps out instead of the kernel breaking:
OverflowError: map size not valid in python

I'm having a lot of issues getting it down to a minimum reproducible example. It is erroring out in a number of weird ways. If I cannot reduce it down in the next 45 minutes or so, I'll send you an email with the full data set and full range of code.
The newest thing that's popped up is:
OverflowError Traceback (most recent call last)
OK, this particular exception doesn't seem hard.

This issue was solved with an updated package version emailed to me by hzzyy.
