解决方案

问题原因

在matplotlib的mac os图像渲染后端(默认使用Cocoa API渲染的后端是什么).有 Qt4Agg 和 GTKAgg 并且作为后端不是默认的.设置与其他windows或linux os不同的macosx后端.

解决方案

• 我假设您已经安装了 pip matplotlib，在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

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>
  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()
  File "//anaconda/lib/python2.7/site-packages/matplotlib-1.3.1-py2.7-macosx-10.5-x86_64.egg/matplotlib/backends/__init__.py", line 28, in 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.

解决方案

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 are 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.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg
