解决Pycharm无法显示matplotlib绘图问题

来源:转载

最近开始接触matplotlib,

1.首先安装matplotlib库和其依赖的一些其他库,例如:numpy,scipy和pandas等

2.开始进行简单的编码工作,并在PyCharm中运行,出现如下错误:

Traceback (most recent call last): File "J:/MyGit/pythonTest/GetTegeather/test06.py", line 4, in <module> import matplotlib.pyplot as plt File "C:/Users/Administrator/AppData/Local/Programs/Python/Python36-32/lib/site-packages/matplotlib/pyplot.py", line 115, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "C:/Users/Administrator/AppData/Local/Programs/Python/Python36-32/lib/site-packages/matplotlib/backends/__init__.py", line 62, in pylab_setup [backend_name], 0) File "J:/software/PyCharm 2017.3.1/helpers/pycharm_matplotlib_backend/backend_interagg.py", line 17, in <module> verbose = matplotlib.verboseAttributeError: module 'matplotlib' has no attribute 'verbose'

解决步骤如下:

前提:

1.导入正确版本的matplotlib库

2.代码最后调用matplotlibku中pyplot.show()方法

3,无其他低级错误

解决步骤:

1.在导入pyplot之前.需要输入如下步骤:

import matplotlib as mpl

mpl.use('Agg')

import matplotlib.pyplot as plt

....

2.此时运行python程序,虽然不报错,但是并没有绘图界面弹出

在命令号几面输入如下命令:

import matplotlib

print(matplotlib.get_backend())

将得到的字符串结果替换mlp.use('Agg')中Agg'即可

例如:我的print(matplotlib.get_backend())结果为TkAgg,替换后为:

mpl.use('TkAgg')

3.显示正常

4.至于原因,个人能力有限,无法解释透彻,

有大神直接更改matplotlibrc文件中backend的值(backend选项改成你系统的图形环境),有兴趣的自行摸索
