matplotlib error - no module named tkinter

I tried to use the matplotlib package via Pycharm IDE on windows 10. when I run this code:

from matplotlib import pyplot

I get the following error:

ImportError: No module named 'tkinter'

I know that in python 2.x it was called Tkinter, but that is not the problem - I just installed a brand new python 3.5.1.

EDIT: in addition, I also tried to import 'tkinter' and 'Tkinter' - neither of these worked (both returned the error message I mentioned).

Follow these steps to easily install Tkinter on your PyCharm IDE:

First go to the File: enter image description here

Second is go to New Project Setup > Settings for new projects: enter image description here

And then click the Settings for new projects and you'll get redirected in here: Please make sure to select the Python Interpreter

Please click the + symbol in there: enter image description here

after that install future and there you go... enter image description here

If you’re having pip(which you probably do), open up cmd or powershell on Windows or a terminal window on OS X or Linux and try this(make sure python is in the system path if you’re on Windows):

pip install tkinter

It should take a while to install tkinter, and then try to execute this code block:

from tkinter import *
root = Tk()
# Your code goes here 
root.mainloop()

Hope that this helps! Thank you!

Download Python Setup file and click modify then tick the tcl/tk and install.

After installation is complete go to folder where python is installed ( Default is C:\Users*Your username*\AppData\Local\Programs\Python\Python39\Lib) .

Copy the tkinter folder and paste it in the lib folder of your pycharm project.

Error should be resolved

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 "import tkinter"

p.s. I suggest installing ipython, which provides powerful shell and necessary packages as well.

For Windows users, there's no need to download the installer again. Just do the following:

  1. Go to start menu, type Apps & features,
  2. Search for "python" in the search box,
  3. Select the Python version (e.g. Python 3.8.3rc1(32-bit)) and click Modify,
  4. On the Modify Setup page click Modify,
  5. Tick td/tk and IDLE checkbox (which installs tkinter) and click next.

Wait for installation and you're done.

I had the same issue on Win x86/64 because my custom Python3.7 installation did not include Tcl packages, so just modify or re-install your python

For the poor guys like me using python 3.7. You need the python3.7-tk package.

sudo apt install python3.7-tk

$ python
Python 3.7.4 (default, Sep  2 2019, 20:44:09)
[GCC 5.4.0 20160609] on linux

>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tkinter'
>>> exit()

Note. python3-tk is installed. But not python3.7-tk.

Maybe you installed python from source. In this case, you can recompile python with tcl/tk supported.

  1. Complie and install tcl/tk from http://www.tcl.tk/software/tcltk/download.html, I'll suppose you installed python at /home/xxx/local/tcl-tk/.
# install tcl
wget -c https://prdownloads.sourceforge.net/tcl/tcl8.6.9-src.tar.gz
tar -xvzf tcl8.6.9-src.tar.gz
cd tcl8.6.9
./configure --prefix=/home/xxx/local/tcl-tk/
make
make install

# install tk
wget -c https://prdownloads.sourceforge.net/tcl/tk8.6.9.1-src.tar.gz
tar -xvzf tk8.6.9.1-src.tar.gz
cd tk8.6.9.1
./configure --prefix=/home/xxx/local/tcl-tk/
make
make install
  1. Recompile python with tcl/tk supported, for example:
# download the source code of python and decompress it first.

cd <your-python-src-dir>
./configure --prefix=/home/xxx/local/python \
 --with-tcltk-includes=/home/xxx/local/tcl-tk/include \
 --with-tcltk-libs=/home/xxx/local/tcl-tk/lib
make 
make install

you can use 

import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt

if you dont want to use tkinter at all.

Also dont forget to use %matplotlib inline at the top of your notebook if using one.

EDIT: agg is a different backend like tkinter for matplotlib.

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()

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

On CentOS 7 and Python 3.4, the command is sudo yum install python34-tkinter

Sometimes (for example in osgeo4w distribution) tkinter is removed.

Try changing matplotlib backend editing matplotlibrc file located in [python install dir]/matplotlib/mpl-data/matplotlibrc changing The backend parameter from backend: TkAgg to something other like backend: Qt4Aggas described here: http://matplotlib.org/faq/usage_faq.html#what-is-a-backend

If you are using python 3.6, this worked for me:

sudo apt-get install python3.6-tk

instead of

sudo apt-get install python3-tk

Which works for other versions of python3

For windows users, re-run the installer. Select Modify. Check the box for tcl/tk and IDLE. The description for this says "Installs tkinter"

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

On Centos, the package names and commands are different. You'll need to do:

sudo yum install tkinter

To fix the problem.
