Matplotlib只是给出错误消息

Question

我正在尝试使用Matplotlib.我之前在工作中使用它并且运行得很好.我正在使用IDLE环境,我在Matplotlib网站上看到交互模式在IDLE中不起作用,但在这种情况下这应该不重要.此外,该库似乎导入正常:

>>> import numpy as np
>>> import matplotlib as plt
>>> x = np.arange(0,3 * np.pi, 0.1)
>>> y = np.sin(x) 
>>> plt.plot(x,y)
Traceback (most recent call last):
   File "<pyshell#7>", line 1, in <module>
  plt.plot(x,y)
  AttributeError: 'module' object has no attribute 'plot'

>>> plt.show()
Traceback (most recent call last):
  File "<pyshell#8>", line 1, in <module>
  plt.show(x,y)
  AttributeError: 'module' object has no attribute 'show'

Answer 1

更改

import matplotlib as plt
