python-cdo error

Dear CDO users,

I installed CDO on my mac using anaconda. CDO runs properly via command line. However, when I try to call CDO from python, the follow message shows up:
from cdo import *
cdo = Cdo()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/yfu347/opt/anaconda3/lib/python3.9/site-packages/cdo.py", line 156, in init
self.operators = self.__getOperators()
File "/Users/yfu347/opt/anaconda3/lib/python3.9/site-packages/cdo.py", line 236, in __getOperators
version = parse_version(getCdoVersion(self.CDO))
File "/Users/yfu347/opt/anaconda3/lib/python3.9/site-packages/cdo.py", line 78, in getCdoVersion
return match.group(1)
AttributeError: 'NoneType' object has no attribute 'group'

Can anyone help me with this? Thank you very much and Happy new year!

I'll take a note.

I'm getting the same error - in Linux environment. I didn't have this issue before so a little confused what it's happening...

hi guys, happy new year!

I noticed problems with cdo-2.0.0. this is related to slight changes to stderr/stdout handling and I fixed in a development version, but did not create a new release, yet. sorry for that.
