7 years ago What's your matplotlib version? I can't reproduce this with Matplotlib 2.1.0.
Also, did you remove /etc/matplotlibrc? And make sure you don't have another matplotlibrc in your system.

7 years ago The matplotlib version is 2.0.0.
I "removed" the matplotlib file via mv /etc/matplotlibrc /etc/mätpllötlibrc and the ~/.config/matplotlib folder is empty. Under these conditions starting spyder via the terminal gives me the following error messages:

In [2]: There's nothing related to Spyder in the traceback you posted, except for the sitecustomize parts, that doesn't have anything to do with Matplotlib.
As the last part of your traceback seems to indicate, this is an installation problem with Matplotlib. Sorry, but I don't know how else yo help you.

7 years ago Even your initial error
warnings.warn('Could not find matplotlibrc; using defaults')seems to point out to a Matplotlib packaging problem in Fedora. I'd suggest you to raise this issue with the Fedora developers.

7 years ago To summarize the two testcases:
/etc/matplotlibrc file causes the behaviour described in my first post./etc/matplotlibrc file causes the behaviour described in my last post. So I have one last question: Why should I/one remove the /etc/matplotlibrc file? Apparently matplotlib works better if a /etc/matplotlibrc is provided (at least I can plot via a normal Python3 terminal).

7 years ago Could you download and try this with Anaconda, please?
I think this whole problem is generated by the way matplotlib is packaged in Fedora, so I'm almost sure it won't appear in Anaconda.

7 years ago I was looking for differences between an Spyder and matplotlib versions between linux distros and pip. For this I scanned the spyder/matplotlib folders of the different distros/pip via the command diff -r DIR1 DIR2.
I ignored differences in .pyc and .so files in the following.
Fedora_spyder is a copy of the Fedora folder /usr/lib/python3.6/site-packages/spyder, Ubuntu_spyder is a copy of the spyder folder from the ubuntu package python3-spyder_3.2.4+dfsg1-1_all.deb and the Pip_spyder is a copy from the spyder folder in the local virtual environment ~/LokaleProgramme/python36-venv/lib/python3.6/site-packages/spyder.The comparison of Fedora_spyder and pip_spyder gives no difference in any interesting .py file
whereas the comparison of Fedora_spyder and Ubuntu_spyder gives the following difference.
diff -r Fedora_spyder/__init__.py Ubuntu_spyder/__init__.py

7 years ago @JakobJakobson, thanks for investigating further this issue. I'm working on a fix for this and issue #5541 right now.
I was not seeing this problem because I had a matplotlibrc in my home dir that superseded the one in /etc.

7 years ago Thanks @ccordoba12. Could you tell me the underlying problem? To me the bug is still very weird, chaotic, arbitrary and far from any logic.

7 years ago In this case it seems Spyder is not setting the Matplotlib backend correctly.
Please test PR #5758 to see if it fixes this problem.

7 years ago And don't forget to restore your /etc/matplotlibrc file. That PR should take care of that.

Description of your problem
The TkAgg/Tkinter graphic backends behaves differently (one time it shows a plot, one time it shows a blank canvas) depending on the choice of the dialog
Preferences -> Run -> ConsoleI ran into this issue by investigating the bug #5541 and I would be glad if you could give me hints for debugging.
What steps will reproduce the problem?
Take the following script
Select the graphic backend as
TkinterviaPreferences-> IPython Console -> Graphics -> Graphics -> Graphics backendThen test the two cases:
Execute in external system terminalviaPreferences -> Run -> Consolein the external system terminal.Execute in current consoleviaPreferences -> Run -> Consolein the current IPython console.What is the expected output? What do you see instead? In case A everything works fine (Screenshots "CaseA")
whereas case B gives me the following output on the console
and a blank canvas in the plot window.
Also you can't close the plot window as it doesn't react on clicking.
Please provide any additional information below It's an Fedora installation.
