macOSX中使用python matplotlib模組的問題解決

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

>>> import numpy as np>>> import matplotlib.pyplot as pltTraceback (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 _macosxRuntimeError: 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.

網路上介紹了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下的模組，如pyplot等之前添加上面2句>>> import matplotlib.pyplot as plt

方法二：

在每個python指令檔中都這麼寫，有些彆扭。

添加一下matplotlib的配置：

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