ModuleNotFoundError only on JupyterHub

[asnaylor]

When i run this line on JupyterHub in a cell:

from balsam.api import ApplicationDefinition

I get this error message:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)

     17 class PeriodicMemoryHandler(logging.handlers.MemoryHandler):

ModuleNotFoundError: No module named 'multiprocessing_logging'

What's odd is that I don't get an error message when i run that from either in a python script or in an interactive python session.

Python 3.9.16
balsam==0.7.0a21

Determined the issue was due to a problem between move python installs between cori and perlmutter.
