from matplotlib.backends import _tkagg ImportError: cannot import name _tkagg

Question

While trying to run this example to test how matplotlib works with Tkinter, I am getting the error:

(env)fieldsofgold@fieldsofgold-VirtualBox:~/new$ python test.         


        

Answer 1

Try following this scenario:

sudo apt-get update

sudo apt-get install tk tk-dev

sudo pip uninstall matplotlib 

sudo pip install matplotlib

EDIT:

Try:

sudo pip uninstall matplotlib 

sudo apt-get install python-matplotlib

EDIT2:

sudo apt-get install tk8.6-dev

sudo apt-get remove python-matplotlib

sudo apt-get install python-matplotlib

Answer 2

Python 3.7.4 on Windows 10, replacing NavigationToolbar2TkAgg with NavigationToolbar2Tk works for me.

Change from:

from matplotlib.backends.backend_tkagg import ( FigureCanvasTkAgg, NavigationToolbar2TkAgg)

To:

from matplotlib.backends.backend_tkagg import ( FigureCanvasTkAgg, NavigationToolbar2Tk)

Answer 3

I just ran into this (Ubuntu 15.10 but same idea) and fixed it by:

sudo apt-get install tk-dev
pip uninstall -y matplotlib
pip --no-cache-dir install -U matplotlib

I think the third step was the critical one; if the cache is permitted then pip appeared to be just using the previously-built installation of matplotlib.

You can also manually remove the previously-built matplotlib; on Ubuntu it lives in ~/.cache/pip somewhere. (I couldn't find a way for pip to clean up its cache unfortunately.)

Answer 4

replacing NavigationToolbar2TkAgg with NavigationToolbar2Tk also works in Python 3.8.5 (MacOS Catalina).

Answer 5

One answer to this question suggests the error is due to a missing Visual C++ Redistributable for Visual Studio 2015 . Installing it solved the problem for me.
