Description Andrew McNabb 2012-12-04 18:18:42 UTC
With python-matplotlib-1.2.0-4.fc18.x86_64, importing pylab gives an ImportError:

ImportError: No module named backend_tkagg

If pylab is unsupported due to a missing dependency, then pylab.py should not be included in the RPM. If pylab should be able to work even without backend_tkagg, then matplotlib should be patched to not try to load this backend.

Comment 1 Paulo Andrade 2012-12-04 19:22:37 UTC
Thanks for the bug report. I did the update to python-matplotlib-1.2.0
and this was not properly tested. Right now I suggest either installing
python-matplotlib-tk or running something like:
$ echo "backend: gtk" >> ~/.matplotlib/matplotlibrc

I will try to make a newer update to correct this issue (using tk
as default backend and splitting it in a separate package).

Comment 2 Paulo Andrade 2012-12-05 01:36:28 UTC
I did build f18 and rawhide test packages and this problem has
been fixed. The main cause was that it did not default to the
gtk backend because setup.py was failing to "detect" a working
pytgk, wrapping it with xvfb-run corrected the problem.
I also update the package slightly to correct a bug in the tk
detection patch and reenabled the wx backend, that is supported
only in the python2 build. Also in the commit I did split the
qt4 backend and added proper requires.
