python ImportError: No module named Tkinter - python-2.7

Question

Every time I tried to run import matplotlib,
I have error ImportError: No module named Tkinter.
The output result is as listed below:
Python 2.7.5 (default, Aug 2 2016, 04:20:16)

ImportError: No module named Tkinter
I tried to install the tk.x86_64 and tk-devel.x86_64 packages, and tried to reinstall the python package but the error still appeared.
Also I tried to import Tkinter but I got the following error.

Does anyone have a workaround for this error?

Answer 1

I'm using python2.7.12 on ubuntu16.04.
I installed it with this command:
sudo apt-get install python-tk

Answer 2

I tried to install tkinter package for python2.7.5 from the following link:
tkinter package
Also I found there is dependency library libTix.so()(64bit) for tkinter package and i got it from the following link: libTix.so()(64bit) package
after that i installed both then I could import Tkinter and import matplotlib.pyplot as plt with no errors.

Answer 3

My 2 cents. Open a terminal and type the following.
$ python
Python 2.7.12 (default, Nov 19 2016, 06:48:10)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>>
If you do not get an error like below then your Tkinter is fine and the problem is with matplotlib. Then try removing and reinstalling matplotlib.

ImportError: No module named tkinter

Answer 4

I was getting the error "ImportError: No module named '_tkinter'" for python3.5 in-spite of installing python3-tk and tkinter-dev.
It showed the error in following file:
File "/usr/local/lib/python3.5/tkinter/init.py", line 35, in
import _tkinter # If this fails your Python may not be configured for Tk
It got resolved for me by simply running the python from /usr/bin like /usr/bin/python3.5 from terminal!
In short, please ensure the python version being run from terminal has the tkinter installed and configured :)
My PC configuration: Ubuntu16.04 with default python2.7 and python3.5

Answer 5

I faced the same issue on a RHEL 7 machine. There was no python-tk package that could be installed. I found the solution here which solved the issue for me:
sudo yum install tkinter
This should work for RHEL machines using Python 2.
