BUG: Can't parse version in threadpoolctl #131
Description
Over in MNE-Python we install threadpoolctl via conda-forge and do theadpool_info(), and on a Windows Python 3.9 build we just recently started getting:
Traceback (most recent call last):
File "C:\Miniconda\Scripts\mne-script.py", line 33, in <module>

config = get_config().split()
AttributeError: 'NoneType' object has no attribute 'split'
This is a bit mysterious to me since the threadpoolctl on conda-forge is ~7 months old. Any ideas how this get_config() could return None, and if so, how it could be worked around to not raise an error here?
