解决办法：
Pycharm中配置cando环境
Page01.py文件：
# coding:utf-8
from matplotlib import pyplot as plt
x = range(2, 26, 2)
y = [15, 13, 14.5, 17,20,25,26,26,24,22,18,15]
plt.plot(x,y)
plt.show()
运行简单的画图效果程序报错：

raise ImportError(msg)
ImportError:
Importing the multiarray numpy extension module failed. Most

If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: DLL load failed: 找不到指定的模块。

解决办法将D:\ProgramData\Anaconda3\Library\bin加入环境变量:
