问题描述：

在macos上使用import matplotlib.pyplot时候遇到报错：

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. If you are Working with Matplotlib in a virtual enviroment see 'Working with Matplotlib in Virtual environments' in the Matplotlib FAQ

解决方法：

在~/.matplotlib/matplotlibrc文件中添加一行：backend: TkAgg

echo "backend: TkAgg" >> ~/.matplotlib/matplotlibrc

在import matplotlib.pyplot前添加：

import matplotlib
matplotlib.use('TkAgg')
