DocTest on doc/TutorialsPerformance.rst gives a warning
Created by: siebenkopf
When I execute the doctest, I get the following warning:
Document: doc/TutorialsPerformance
/idiap/group/torch5spro/nightlies/externals/v3/ubuntu-10.04-x86_64/lib/python2.6/site-packages/matplotlib/init.py:908: UserWarning: This call to matplotlib.use() has no effect because the the backend has already been chosen; matplotlib.use() must be called before pylab, matplotlib.pyplot, or matplotlib.backends is imported for the first time.
It seems that there is something wrong with the call matplotlib.use('pdf') #non-interactive avoids exception on display in line 120 of the .rst file.
@André: Since the file header says that you are the author, I assigned this issue to you. Thanks for fixing that. Manuel
