Thanks, I guess my problem is that I am using the latex prosper package to
make presentation slides but I cannot compile prosper documents with
pdflatex (see here <>).
Sorry, I see that this is not a matplotlib specific question so I will try
to find a solution somewhere else.

Have a look at the LaTeX beamer package which produces
PDF directly. Thus it's easy to include your PDF pictures
without the need to convert them.
