ipython笔记本中的“import matplotlib.pyplot as plt”

我是ipython笔记本的新手，但每次运行import matplotlib.pyplot as plt时都会收到以下错误消息。我正在使用Mac。它可以与内置的python或Canopy配合使用。该问题仅在ipython notebook存在。我也尝试更新numpy，但问题仍然存在。会感激有人来帮忙！ipython笔记本中的“import matplotlib.pyplot as plt”

尝试运行'ipython笔记本--pylab' – askewchan

嗨，感谢您的帮助。我尝试了下面的错误消息。我试图再次安装matplotlib，并再次运行该程序，但在ipython笔记本中仍然收到相同的错误消息。 '警告：试图在virtualenv工作。如果遇到问题，请在virtualenv中安装IPython。 ------------------------------------------------- -------------------------- 无追踪（最近呼叫最后一个）无：无 [IPKernelApp]警告| Eventloop或matplotlib集成失败。是否安装了matplotlib？' – user3084957

它看起来像您的安装是borked。看起来你是在一个mac上，似乎有路径正确的地方性问题。你是怎么安装'matplotlib'/enthought？ – tacaswell

你对Canopy的态度如何？我有一些尝试使用Canopy的配置问题，并最终使用Homebrew来自定义我自己的Python安装。有在真正有用的指南：

http://joernhees.de/blog/2013/06/08/mac-os-x-10-8-scientific-python-with-homebrew/

我遵循了所有这些步骤，除了两个或三个（不记得确切）中的“酿造安装”方法没有工作，我不得不点子该模块，而不是。

我刚打开一个IPython笔记本来验证我的发行版中的一切正常。

from matplotlib import pyplot as plt 
import numpy as np 

x = np.linspace(0, 2*np.pi, 100) 
y = np.sin(x) 
plt.plot(x, y) 
plt.show()

以上给出了预期的输出。
