python matplotlib framework under macosx? macosx下的python matplotlib框架？ 11 answers 11个答案

I have issue after installing the matplotlib package unable to import matplotlib.pyplot as plt . 我在安装matplotlib软件包后无法将matplotlib.pyplot作为plt导入 。 Any suggestion will be greatly appreciate. 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()

    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). 问题原因在mac os图像渲染中，matplotlib的后端（默认情况下使用Cocoa的API渲染的后端是什么）。 There is Qt4Agg and GTKAgg and as a back-end is not the default. 有Qt4Agg和GTKAgg，作为后端不是默认值。 Set the back end of macosx that is differ compare with other windows or linux os. 设置macosx的后端与其他windows或linux os相比有所不同。

I resolve this issue following ways: 我通过以下方式解决此问题：

I assume you have installed the pip matplotlib, there is a directory in you root called ~/.matplotlib . 我假设您已经安装了pip matplotlib，您的根目录中有一个名为~/.matplotlib 。
Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg 在那里创建一个~/.matplotlib/matplotlibrc文件并添加以下代码： backend: TkAgg
