If you are using fedora then first install tkinter  sudo dnf install python3-tkinter   I don t think you need to import tkinter afterwards I also suggest you to use virtualenv     python3 -m venv myvenv   source myvenv bin activate   And add the necessary packages using pip

Almost all answers I searched for this issue say that Python on Windows comes with tkinter and tcl already installed  and I had no luck trying to download or install them using pip  or actviestate com site  I eventually found that when I was installing python using the binary installer  I had unchecked the module related to TCL and tkinter  So  I ran the binary installer again and chose to modify my python version by this time selecting this option  No need to do anything manually then  If you go to your python terminal  then the following commands should show you version of tkinter installed with your Python   import tkinter import  tkinter tkinter  test

For Linux Debian based distros  sudo apt-get install python3-tk  RPM based distros  sudo yum install python3-tkinter  For windows  For Windows  I think the problem is you didn t install complete Python package  Since Tkinter should be shipped with Python out of box  See  http   www tkdocs com tutorial install html   Good python distributions for Windows can be found by the companies Anaconda or ActiveState  Test the python module python -c  quot import tkinter quot   p s  I suggest installing ipython  which provides powerful shell and necessary packages as well

On Ubuntu  early 2018  there is no python3 6-tk on ubuntu s  xenial 16 04  normal distributions  so even if you have earlier versions of python-tk this won t work   My solution was to use set everything up with python 3 5    sudo apt install python3 5-tk  virtualenv --python  which python3 5  python-env  source python-env bin activate  pip install -r requirements txt   And now matplotlib can find tkinter   EDIT   I just needed 3 6 afterall  and the trick was to   sudo apt install tk-dev   and then rebuild python3 6  after tk-dev  eg     configure make make install
