Exception ignored in: <function Pool.__del__ at 0x7ffbaf47d9d0>
Traceback (most recent call last):
  File "/root/conda/lib/python3.8/multiprocessing/pool.py", line 268, in __del__
  File "/root/conda/lib/python3.8/multiprocessing/queues.py", line 362, in put
AttributeError: 'NoneType' object has no attribute 'dumps'

Pretty sure that shouldn't be None.

If you don't mind, Would you like to attach the reproducible script for this?

FYI, this bug was an issue with dask: https://github.com/dask/dask/issues/5806
and has been fixed in dask as of (I believe) v2.11.0
