On mac OSX, when using the python matplotlib library, the problem occurs:
>>> import numpy as np
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):

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 using (Ana)Conda please install python.app and replace the use of 'python' with 'pythonw'. See 'Working with Matplotlib on OSX' in the Matplotlib FAQ for more information.
There are 2 methods introduced on the Internet, which can be tested.
method one:
Add the following two lines of code to solve:
>>> import matplotlib
>>> matplotlib.use('TkAgg')
##Add the above 2 sentences before the modules under import matplotlib, such as pyplot, etc.
>>> import matplotlib.pyplot as plt
Method Two:
It's a little awkward to write this in every python script file.
Add the matplotlib configuration:
echo "backend: TkAgg" >> ~/.matplotlib/matplotlibrc
