matplotlib没有属性'pyplot' [英] matplotlib has no attribute 'pyplot'

问题描述

我可以导入matplotlib，但是当我尝试运行以下命令时:

I can import matplotlib but when I try to run the following:

matplotlib.pyplot(x)

我得到:

Traceback (most recent call last):
   File "<pyshell#31>", line 1, in <module>
       matplotlib.pyplot(x)
AttributeError: 'module' object has no attribute 'pyplot'

推荐答案

是matplotlib的子模块，无法通过简单的import matplotlib导入.

pyplot is a sub-module of matplotlib which doesn't get imported with a simple import matplotlib.

>>> import matplotlib
>>> print matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
>>> import matplotlib.pyplot
>>> 

这似乎很常见:import matplotlib.pyplot as plt此时，您可以使用其中包含的各种函数和类:

It seems customary to do: import matplotlib.pyplot as plt at which time you can use the various functions and classes it contains:

p = plt.plot(...)
