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 "<stdin>", line 1, 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.

This is happening because you have not set the image rendering backend of matplotlib. For Mac OS X  Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg
