Question

安装 matplotlib 软件包后无法导入matplotlib.pyplot作为plt ，我遇到了问题。任何建议都将非常感激。

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", 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()

    globals(),locals(),[backend_name],0)

    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.

问题原因 在mac os image中渲染matplotlib的后端（默认情况下使用Cocoa的API渲染什么后端）。有Qt4Agg和GTKAgg，作为后端不是默认值。设置macosx的后端与其他windows或linux os相比有所不同。

我按照以下方式解决了这个问题：

我假设您已经安装了pip matplotlib，您的根目录中有一个名为~/.matplotlib的目录。
在那里创建一个文件~/.matplotlib/matplotlibrc并添加以下代码：backend: TkAgg

从这个link你可以尝试不同的图表。
