Import error when trying to import Tkinter: cannot import name _cnfmerge

I encountered this error when trying to import Tkinter

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64 bit (AMD64)] on win32

Type "help", "copyright", "credits" or "license" for more information.

>>> import Tkinter

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>
  File "Tkinter.py", line 3, in <module>

    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg

  File "C:\Python27\lib\site-packages\matplotlib\backends\backend_tkagg.py", line 7, in <module>

    from six.moves import tkinter_filedialog as FileDialog
  File "C:\Python27\lib\site-packages\six.py", line 203, in load_module
    mod = mod._resolve()

  File "C:\Python27\lib\site-packages\six.py", line 115, in _resolve
    return _import_module(self.mod)

  File "C:\Python27\lib\site-packages\six.py", line 82, in _import_module
    __import__(name)

  File "C:\Python27\lib\lib-tk\FileDialog.py", line 12, in <module>
    from Dialog import Dialog

  File "C:\Python27\lib\lib-tk\Dialog.py", line 4, in <module>
    from Tkinter import _cnfmerge

ImportError: cannot import name _cnfmerge

I am not sure what is going on here, but I think it might have to do with numpy.

I am building an application in python3+tkinter and had the same problem. I replaced 'NavigationToolbar2TkAgg' with 'NavigationToolbar2Tk' and it compiled successfully. Try replacing it and see if it works for you.

from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2Tk

The real Tkinter.py certainly does not contain any references to matplotlib. You have another file with the same name on Python's search path, which is shadowing the real module.
