I have no file or folder named ~/.aksetup-defaults.py.
Maybe it is not installed in the home directory as Thomas suggested in my
case.
Maybe it has to do with the fact that I installed codepy with copperhead
and not as a standalone.
Maybe Bryan has some extra insight as to what might have happened.
I will try and fix it as soon as i have more time in my hands.
Thanks for the help anyway.
