Description jakob.jakobson18 2017-10-25 13:31:48 UTC 
Description of problem:
After I messed up my spyder3 installation by installing various packages (in an attend to solve bug 1502871), I ended up with an unusable graphic backend "Tkinter".


Version-Release number of selected component (if applicable):
python3-spyder.noarch                   3.2.2-1.fc26                    @updates


How reproducible:
On my system it's very reproducible.

Steps to Reproduce:
1. Install lots of things.
2. Reset spyder3 to its default settings.
3. Set tmp.py in ~/.local/spyder-py3 to the tmp.py file of the attachment.
4. Select the graphic backend "Tkinter" from Tool -> Preferences -> IPython Console -> Graphics tab - Backend selection [Tkinter]
5. Run tmp.py file.


Actual results:
The tmp.py file runs and the graphic window opens but no graphic is drawn.

Expected results:
Spyder3 shows the expected graphic.


Additional info:
Sorry that I'm filing so many bugs this afternoon but if you need further information, just say it.

This is the actual graphic window.

I am sorry but I cannot reproduce most of these issues. I am able to plot using inline, gtk3 and tkinter. 

qt4 crashes, but I wonder if that has to do with spyder being compiled with QT5 completely. I might be wrong here.

qt5 plot opens but does not show anything - just like the screenshot in comment #2.

I wonder if this is a matplotlib-qt5 issue. Because, every other setting seems to work fine ...

Hi,
Set the relevant preferences to Tkinter, and receive the error :

ModuleNotFoundError: No module named 'matplotlib.backends.backend_qt4agg'

As per https://bugzilla.redhat.com/show_bug.cgi?id=1502871

Regards,
Shadders.
