At this point, you could have come to this list, asking for help - and
posting the *entire* traceback. It may have mentioned a file name,
which would give a strong clue; otherwise, there'd be an error like
this:
rosuav@sikorsky:~/tmp$ echo 'print("Hello, world!")' >pickle.py
rosuav@sikorsky:~/tmp$ python3 -m pip list
Hello, world!
Traceback (most recent call last):

And someone would have suggested changing to another directory, or
running something like this:
rosuav@sikorsky:~/tmp$ python3 -c 'import pickle; print(pickle.__file__)'
Hello, world!
/home/rosuav/tmp/pickle.py
which shows up the issue.
Don't get mad - get even! Or even better, get help! But show us the
entire exception traceback, not just "got an exception".
