Note that you can get the basic functionality (without plotting) by commenting line 9 from the file /usr/lib/python2.7/site-packages/mnemosyne/pyqt_ui/statistics_wdgts_plotting.py:

- from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
+ #from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas

Thanks for your quick and helpful response. I can confirm that downgrading to python2-matplotlib 1.3.1-4 fixed the issue for me.

As far as I can see, though, the current version of python2-matplotlib in [community] has been 1.4.0-1 since 2014-08-28.

For now, you can make it work by downgrading python2-matplotlib to version 1.3.x (which is still the current version in [community] -- only version 1.4.0 from [community-testing] is causing the issue).

As for the python2-pyqt -> python2-pyqt4 rename, I've updated the PKGBUILD now to reflect this.

Still investigating the issue with matplotlib 1.4 though.

@vagyok: Thanks for reporting; I see the same errors. For what it's worth, python2-pyqt4 is the correct dependency as Mnemosyne is a Qt4 program; the fact that the matplotlib dependency tries to load Qt5 is strange. I'll investigate.

python2-pyqt , which is currently a dependency of this package, no longer seems to exist - it is apparently either python2-pyqt4 (which replaced python2-pyqt ) or python2-pyqt5 in [extra] now.

Trying it with python2-pyqt4 (and its pyqt4-common dependency) gave me the following error:

File "/usr/lib/python2.7/site-packages/matplotlib/backends/qt_compat.py", line 91, in <module>
from PyQt5 import QtCore, QtGui, QtWidgets
ImportError: No module named PyQt5

(in full: http://pastebin.com/FMT3WFsB )

Trying it with both python2-pyqt4 (and its pyqt4-common dependency) and python2-pyqt5 (and its pyqt5-common dependency) installed before rebuilding the package gave me the following error:

File "/usr/lib/python2.7/site-packages/matplotlib/backends/qt_compat.py", line 91, in <module>
from PyQt5 import QtCore, QtGui, QtWidgets
RuntimeError: the PyQt5.QtCore and PyQt4.QtCore modules both wrap the QObject class

(in full: http://pastebin.com/6aMr6es9 )

Trying to remove python2-pyqt4 (and/or pyqt4-common) so as to use only python2-pyqt5 and pyqt5-common failed because this package depends on python2-matplotlib in [community], which requires python2-pyqt4 explicitly, which, in turn, requires pyqt4-common.

Any suggestions?

Glad it worked out :)

You are a godsend, smls!!! Thanks to the path info you gave me for latex tmp files created by Mnemosyne, I was able to track down tmp.tex and open it in Gummi, my LaTeX editor. The problem was that tmp.tex failed to build at all due to a missing font!

My LaTeX preamble in Mnemosyne was as follows:

\documentclass[12pt]{article}
\usepackage{amsmath, amsfonts, amssymb, cancel}
...

Unfortunately the LaTeX font package cancel.sty in \usepackage above was missing from my Arch install! The font is provided by the package texlive-extralatex

Now creating LaTeX cards works perfectly when running Mnemosyne as a local user. I wonder why running Mnemosyne as root allowed LaTeX to render despite missing one font file, however...

@gojun077
If the problem persists, try manually following the individual steps that Mnemosyne performs, to see where exactly the problem lies:

1) Create a file called tmp.tex with the following content:

\documentclass[12pt]{article}
\pagestyle{empty}
\begin{document}
$\sqrt{x^3}$
\end{document}

2) Execute the command...

latex tmp.tex

...which will try to create a file called tmp.dvi in the same folder. Be sure to also check the console output for errors.

3) Execute the command...

dvipng -D 200 -T tight tmp.dvi

...which will try to create a file called tmp1.png in the same folder.

@gojun077
That's strange, there should not be any need for special permissions or groups - for me it just works.

Mnemosyne creates its LaTeX related temporary tex/dvi/png files in this folder (insert the name of your Mnemosyne database in place of "___TMP___", if you have given it an explicit name.):

~/.local/share/mnemosyne/___TMP___.db_media/_latex

Make sure that there are no permission problems with this folder, and if there are old files there that may cause problems, remove them.
