I'm trying to run some scripts associated with a paper I was reading. They use
the matplotlib to generate figures which in turn calles numpy. I'm new to
python, but I'm very familiar with perl. I'm getting the following error, and
I'm not quite sure what is causing it. Can anyone here offer any suggestions?
