I don't know about matplotlib, but this code snippet works here.

This looks strange, since the call to attributes() seems to be fine.
I can only guess here. You are apparently using a custom python version,
how do you start the program? Is it possible that somehow the system
default python install conflicts with your custom python here? (Not sure
if this could cause an error like this at all, though.)

Maybe for a test you could try to comment out line 610 in
backend_tkagg.py and see what happens then?

Regards

Michael
