No module named Tkinter

Question

I have a small script in python2.7 that I want to convert into Windows executable. I use pyinstaller for this.

The script:

import sys 
import matplotlib.pyplot as plt
import matplotlib.image as mpimg


def get_inputs():
    coor = raw_input(">>>top x left: ").replace(" ", "")
    top, left = coor.split("x")
    top = int(top.strip())
    left = int(left.strip())
    return top, left 

def plot_location(top, left):
    img= mpimg.imread('nbahalfcourt.jpg')
    plt.imshow(img)
    plt.scatter(left, top)
    plt.grid()
    plt.show()

def main():
    top, left = get_inputs()
    plot_location(top, left)

if __name__ == '__main__':

    print "Input top x left coordinates (no space) eg: 44x232"

    run = True 
    while run:
        main()

Basically, the script just plots a point on a grid.

The converting process finishes successfully. When I run the .exe however I've got the ImportError (see below) even though I have no reference to Tkinter anywhere.

What could went wrong here?

I have a feeling that `matplotlib` uses the `Tkinter` module internally, but imports it in a non-standard way. Then `pyinstaller` doesn't notice Tkinter is needed, and subsequently doesn't bundle it into the executable. I wonder if explicitly putting `import Tkinter` at the top of your script would help? — Kevin, Oct 07 '14 at 17:32
That did the trick! Thanks buddy. Post it as an answer if you wish, so I can accept for the record. — nutship, Oct 07 '14 at 17:49
explicitly importing them so `pyinstaller` can definitely see them is a perfectly good solution, there's also command line flag for explicitly telling `pyinstaller` to include extra modules `--hidden-import=Tkinter` — GP89, Oct 07 '14 at 18:02

Just for the record, I had to `import FileDialog` along with the Tkinter import. – nutship Oct 07 '14 at 17:54

I had the same issue and none of the solutions here worked. I was using Pyinstaller 3.2 (the latest version at the time) and everything was fixed (and no import statements needed) when I upgraded to the latest developer version using

pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip

This seems to indicate that at the times of writing this that all the kinks to this issue are still being worked out

EDIT: As of January 15 2017 Pyinstaller version 3.2.1 was released. I now use this and it solves this issue along with others like this and this that I could previously only solve by using the developer version. So I highly recommend upgrading to the latest version if you haven't already.

Yep, this worked for me. Also using 3.2 and getting import error for Tkinter. Installing the latest developer version resolved it thanks. – David Clarke Sep 08 '16 at 22:35
Also for me using the 3.3 dev version was the only way to fix the issue, thanks – dipanda Nov 07 '16 at 09:02
