ipython筆記本中的「import matplotlib.pyplot as plt」

我是ipython筆記本的新手，但每次運行import matplotlib.pyplot as plt時都會收到以下錯誤消息。我正在使用Mac。它可以與內置的python或Canopy配合使用。該問題僅在ipython notebook存在。我也嘗試更新numpy，但問題仍然存在。會感激有人來幫忙！ipython筆記本中的「import matplotlib.pyplot as plt」

嘗試運行'ipython筆記本--pylab' – askewchan

嗨，感謝您的幫助。我嘗試了下面的錯誤消息。我試圖再次安裝matplotlib，並再次運行該程序，但在ipython筆記本中仍然收到相同的錯誤消息。 '警告：試圖在virtualenv工作。如果遇到問題，請在virtualenv中安裝IPython。 ------------------------------------------------- -------------------------- 無追蹤（最近呼叫最後一個）無：無 [IPKernelApp]警告| Eventloop或matplotlib集成失敗。是否安裝了matplotlib？' – user3084957

它看起來像您的安裝是borked。看起來你是在一個mac上，似乎有路徑正確的地方性問題。你是怎麼安裝'matplotlib'/enthought？ – tacaswell

你對Canopy的態度如何？我有一些嘗試使用Canopy的配置問題，並最終使用Homebrew來自定義我自己的Python安裝。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/

我遵循了所有這些步驟，除了兩個或三個（不記得確切）中的「釀造安裝」方法沒有工作，我不得不點子該模塊，而不是。

我剛打開一個IPython筆記本來驗證我的發行版中的一切正常。

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()

以上給出了預期的輸出。
