如何使IPython笔记本matplotlib内联 [英] How to make IPython notebook matplotlib plot inline

问题描述

我正在尝试在MacOS X上使用Python 2.7.2和IPython 1.1.0上的IPython笔记本。

I am trying to use IPython notebook on MacOS X with Python 2.7.2 and IPython 1.1.0.

我无法让matplotlib图形显示为内联。

I cannot get matplotlib graphics to show up inline.

import matplotlib
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline  

我还试过％pylab inline 和ipython命令行参数 - pylab = inline 但这没有区别。

I have also tried %pylab inline and the ipython command line arguments --pylab=inline but this makes no difference.

x = np.linspace(0, 3*np.pi, 500)
plt.plot(x, np.sin(x**2))
plt.title('A simple chirp')
plt.show()

除了内联图形，我得到这个：

Instead of inline graphics, I get this:

<matplotlib.figure.Figure at 0x110b9c450>

和 matplotlib.get_backend（）显示我有'模块：//IPython.kernel.zmq.pylab.backend_inline'后端。

推荐答案

我在笔记本的第一个单元格中使用了％matplotlib inline ，它可以正常工作。我想你应该试试：

I used %matplotlib inline in the first cell of the notebook and it works. I think you should try:

%matplotlib inline

import matplotlib
import numpy as np
import matplotlib.pyplot as plt

您也可以随时启动所有IPython内核默认情况下，通过在配置文件中设置以下配置选项来进行内联模式：

You can also always start all your IPython kernels in inline mode by default by setting the following config options in your config files:

c.IPKernelApp.matplotlib=<CaselessStrEnum>
  Default: None
  Choices: ['auto', 'gtk', 'gtk3', 'inline', 'nbagg', 'notebook', 'osx', 'qt', 'qt4', 'qt5', 'tk', 'wx']
  Configure matplotlib for interactive use with the default matplotlib backend.
