I'm decently new to using a Raspberry Pi and I'm trying to set up a simple GUI application to launch from my Pi. I'm using a Raspberry Pi3, with Python 3.4.3 installed.

When I type python:

~$ python
Python 3.4.3 |Continuum Analytics, Inc.| (default, Aug 21 2015, 00:53:08)
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.

When I try to import tkinter:

>>> import tkinter
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/home/pi/miniconda3/lib/python3.4/tkinter/__init__.py", line 38, in <module>
        import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named '_tkinter'
>>>

So, I can see that the error is coming from miniconda3. The only reason I had it installed was to use PyQt5, but I was getting a similar error when I tried to use that, so I switched over to Tkinter because there were more examples of using it with a pi online.

I have run the following commands to try to install Tkinter:

sudo apt-get install tk-dev
sudo apt-get install tk8.6-dev
sudo apt-get install python-imaging-tk
sudo apt-get install python-tk
sudo apt-get install python3-tk

How can I fix this? I have read in some places to make python again, but no one says how to do that.

Thanks guys!

  • It seems you are launching miniconda python not python with comes with raspberry-pi distribution. Could post the output of which python and try if tk works when lauching python using /usr/bin/python – user.dz Mar 25 '17 at 18:17

    @user.dz This was exactly the issue! Now there is no import issue when I try to import. Thank you so much! – J. Schach Mar 25 '17 at 23:56

Install the Tkinter package for writing Tk applications with Python 3.x. In all currently supported versions of Ubuntu, open the terminal and type:

sudo apt install python3-tk # for Python 2.x install python-tk

Then run /usr/bin/python3 to start the default Python 3 that comes with Ubuntu and import tkinter will work.

  • It seems that you are launching mini-conda python not python that comes with raspberry-pi distribution. You could check the output of:

    which python

    Expected output: /usr/local/bin/python or mini-conda custom installation path (if it was added before.)

  • Test also if Tk works when launching python using absolute path:

    /usr/bin/python

  • To complete my answer, if you like to use miniconda python, use its own installation method:

    conda install packagename

    Reference: Miniconda homepage, :) I'm not aware of the exact package name of tkinter.
