uninstall python, and install a 32 bit version and the 32 bit modules

By the way, do you mind if I ask why you're using PyGraphics? It's
only meant to be used for education (and even there, AFAIK the only
users are the University of Toronto (and even there, I think they
stopped using it because they switched to Python 3 for Coursera and
didn't care enough to upgrade PyGraphics (I am mad about this))).
