This is what happens if you try to load a Bayes pickle created before
classifier.Bayes changed from a new-style class to an old-style class.
You're best off retraining from scratch.  If you're desperate to retrieve
the old data, you can change

class Bayes:

back to

class Bayes(object):

and the pickle should load again.
