ValueError: invalid shape

[csadorf]

After a fresh systemwide install I copied the example files kw.p and nb.p into $HOME/.shakespeare/. When I executed shakespeare -j natnano pnas -o cool_papers.md I get the following output:

Warning: knowledge dir /home/simon/.shakespeare does not contain nb.p (pickled naive bayes object)
Warning: knowledge dir /home/simon/.shakespeare does not contain kw.p (pickled keyword list)

This behavior seems to indicate that the script couldn't locate an knowledge and then barfed in a way it shouldn't have. I will see if I can reproduce this behavior.

I have made changes to the error handling that should prevent this path from executing is no naive bayes and/or keyword list objects are found.
