Question

使用下面的代码生成TclError。

import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt

plt.plot([1,2,3,4], [1,4,9,16], 'ro')
plt.axis([0, 6, 0, 20])
plt.show()

当我在终端中执行我的脚本时，我得到以下内容：

/Users/<username>/anaconda/lib/python2.7/site-packages/matplotlib/__init__.py:1035: UserWarning: Duplicate key in file "/Users/<username>/.matplotlib/matplotlibrc", line #2

TclError

导致此错误的原因是什么？我尝试将backend: TkAgg添加到我的matplotlibrc文件中，但无济于事。

请告知

Answer 1

想出来：

而不是使用：

matplotlib.use('TkAgg')

使用：

matplotlib.use('Qt4Agg')

或任何其他后端

Answer 2

你可以使用＆＃39; TkAgg＆＃39;但需要安装Tkinter而不是conda。针对pil / pillow和matplotlib的Anaconda包似乎没有正确包含TK。用conda安装pip，然后运行pip install pillow matplotlib（Linux）

在Windows上，您可以使用gohlke提供的软件包 http://www.lfd.uci.edu/~gohlke/pythonlibs/ 安装--force-reinstall枕头matplotlib

然后Tkinter TkAgg将工作。
