[英]“import matplotlib.pyplot as plt” in ipython notebook
我是ipython筆記本的新手,但每當我運行import matplotlib.pyplot as plt
時,我都會收到以下錯誤消息。 我正在使用Mac。 它與內置的python或Canopy一起工作正常。 這個問題只存在於ipython notebook
。 我也嘗試更新numpy,但問題仍然存在。 非常感謝有人幫忙!

你對Canopy的承諾如何? 我有一些配置問題試圖使用Canopy,最后使用Homebrew來定制我自己的Python安裝。 有一個非常有用的指南:
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(不記得究竟是哪個)“brew install”方法不起作用,我不得不改變模塊。
我剛打開一個IPython筆記本來驗證我的發行版上的一切正常。
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。
