环境

Tkinter VS tkinter

根据Python介绍发现 在Python2 和Python3 中该包名称是不一样的，在 python2中叫Tkinter； 在python3中叫tkinter

Refer to
Tkinter — Python interface to Tcl/Tk

Note Tkinter has been renamed to tkinter  in Python 3. 
The 2to3 tool will automatically adapt imports when converting your 
sources to Python 3.

Fix

install tkinter under centoer by yum

yum install -y tkinter

Verify

>>>
>>> import Tkinter
>>> import matplotlib.pyplot as plt
>>>
