在mac OSX 上，使用python matplotlib庫時，出現問題：

>>> import numpy as np >>> import matplotlib.pyplot as plt Traceback (most recent call last):File "<stdin>", line 1, in <module>File "/Users/david/anaconda2/envs/tensorflow/lib/python3.6/site-packages/matplotlib/pyplot.py", line 113, in <module>_backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()File "/Users/david/anaconda2/envs/tensorflow/lib/python3.6/site-packages/matplotlib/backends/__init__.py", line 60, in pylab_setup[backend_name], 0)File "/Users/david/anaconda2/envs/tensorflow/lib/python3.6/site-packages/matplotlib/backends/backend_macosx.py", line 19, in <module>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. 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.

網絡上介紹了2中方法， 測試都可以。

方法一：

添加如下兩行 代碼解決:

>>> import matplotlib >>> matplotlib.use('TkAgg')##在import matplotlib下的模塊，如pyplot等之前添加上面2句>>> import matplotlib.pyplot as plt

方法二：

在每個python腳本文件中都這么寫，有些別扭。

添加一下matplotlib的配置：

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