This question already has an answer here:
I have issue after installing the matplotlib package unable to import matplotlib.pyplot as plt. Any suggestion will be greatly appreciate.
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "", line 1, in <module>
  File "//anaconda/lib/python2.7/site-packages/matplotlib-1.3.1-py2.7-macosx-10.5-x86_64.egg/matplotlib/pyplot.py", line 98, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()

    from matplotlib.backends import _macosx
**RuntimeError**: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends.


Problem Cause In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There is Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.
I resolve this issue following ways:
  • I assume you have installed the pip matplotlib, there is a directory in you root called ~/.matplotlib.
  • Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg
From this link you can try different diagram.
