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
问题原因
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.
在 matplotlib 的 mac os 图像渲染后端（默认情况下使用 Cocoa 的 API 进行渲染的后端是什么）。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。
Solution

- I assume you have installed the pip matplotlib, there is a directory in your root called
~/.matplotlib. - Create a file
~/.matplotlib/matplotlibrcthere and add the following code:backend: TkAgg
- 我假设您已经安装了 pip matplotlib，您的根目录中有一个名为
