This tells us the problem originates in a PMW file

And this says its from pymol code.

This list is for problems with the Python language and its standard library.

We are not equipped to support all of the 3rd party modules out there so 
unless you are very lucky and somebody on the list uses pymol and can 
help, you will be better off asking for help on a pymol forum, or by 
contacting the authors.

If you do that, one thing that might help is to provide information 
about the OS you are using, the Python version, and how you are running 
the code. For example, you have not provided any clues above as to what 
actual python code you were trying to run which caused the error 
message. The more context you can provide the easier it will be for the 
pymol experts to see what's gone wrong.
