采用Pycharm用matplotlib绘图时报错AttributeError: module ‘matplotlib’ has no attribute ‘verbose’

1.采用pycharm，在用matplotlib绘图时，报错：

源代码：

import matplotlib.pyplot as plt
squares = [1, 4, 9, 16, 25]
plt.plot(squares)
plt.show()

报错：

Traceback (most recent call last):
  File "E:/Python-example/test1/mpl_squares.py", line 2, in <module>
    import matplotlib.pyplot as plt
  File "D:\Program Files\Python\lib\site-packages\matplotlib\pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "D:\Program Files\Python\lib\site-packages\matplotlib\backends\__init__.py", line 62, in pylab_setup
    [backend_name], 0)
  File "D:\Program Files\JetBrains\PyCharm 2017.3.3\helpers\pycharm_matplotlib_backend\backend_interagg.py", line 17, in <module>
    verbose = matplotlib.verbose
AttributeError: module 'matplotlib' has no attribute 'verbose'

2.解决办法：

在源文件开头添加：

import matplotlib as mpl
mpl.use('Qt5Agg')

最后代码如下：

import matplotlib as mpl
mpl.use('Qt5Agg')
import matplotlib.pyplot as plt
squares = [1, 4, 9, 16, 25]
plt.plot(squares)
plt.show()

运行结果如下：
