【问题描述】:
使用下面的代码,会生成一个 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,我得到以下信息:
/Users/<username>/anaconda/lib/python2.7/site-packages/matplotlib/__init__.py:1035: UserWarning: Duplicate key in file "/Users/<username>/.matplotlib/matplotlibrc", line #2

Exception in Tkinter callback
Traceback (most recent call last):

File "/Users/<username>/anaconda/lib/python2.7/site-packages/matplotlib/backends/tkagg.py", line 30, in blit

TclError
是什么导致了这个错误?我尝试将backend: TkAgg 添加到我的matplotlibrc 文件中,但无济于事。
请指教
