Question

我在终端中运行Ipthon，在linux中运行（不是一个jupyter笔记本）。

在Ipython 2.4.1中，以下命令打开一个弹出式交互式Tk 情节窗口：

(prodEnv)[kv@loowkv1 sandbox]$ ipython
IPython 2.4.1 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.


In [1]: 

In [1]: %matplotlib
Using matplotlib backend: TkAgg
In [2]: import matplotlib.pyplot as plt
In [3]: import numpy as np
In [4]: plt.ion()
In [5]: x = np.arange(0, 4*np.pi, 0.1)
In [6]: y = [np.sin(i) for i in x]
In [7]: plt.plot(x, y, 'g-', linewidth=1.5, markersize=4)
Out[7]: [<matplotlib.lines.Line2D at 0x7f5c8a8b6410>]

在Ipython 5.0.0中，当我使用相同的代码时：

(prodEnv)[kv@loowkv1 sandbox]$ ipython3
Python 3.4.1 (default, Nov  3 2014, 14:38:10) 
Type "copyright", "credits" or "license" for more information.

什么也没出现。如何在Iptyhon 5.0.0中获得弹出的交互式绘图？

Answer 1

使用ipython使用TkAgg输出，即使用tk（python-tk）作为后端。

使用matplotlib后端：TkAgg

但是ipython3，agg

使用matplotlib后端：agg

我尝试使用ipython3和TkAgg后端，它正常工作ipython。您可能需要安装python3-tk才能将TkAgg与matplotlib

一起使用
