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.verbose
AttributeError: 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
