Hi, I somehow missed the other issue while searching for something similar to this, sorry about that. The main issue is that files pickled with python 3.9.0 cannot be read back by using python 3.9.0 if they contain a `uname_result` object. As for expecting pickle to work across different versions: I did not actually think about that. In the original message I mentioned python 3.8.5 as I noticed this issue did not happen in python 3.8.5, so I though it was useful information. To my (hopefully correct) understanding if a python version supports the same protocol that was used to create the pickle file then it is expected to work. For example I have observed that files containing `uname_result` objects pickled with python 3.7.6 are still readable with python 3.8.5. As far as I understand this is the expected behavior.
