Hi guys.
He established matplotlib, but ran into problems. When importing crashes.
https://talk.maemo.org/showthread.php?t=72290 here was proposed solution.

Edit the file /usr/lib/python2.5/site-packages/matplotlib/mpl-data/matplotlibrc (you will have to create the mpl-data dir most likely) to read:
datapath : /usr/share/matplotlib/mpl-data
I also set the datapath and backend in my user directory
Nokia-N900:~# cat /home/user/.matplotlib/matplotlibrc
datapath : /usr/share/matplotlib/mpl-data
backend : GTKAgg

I made as proposed, but it cleared up only with the import problem.
Here is the text of the error:

I dig deeper. Now another error. Cursing at the lack of fonts.

module_path: "murrine" due to the GTK-engine. Solved in writing datapath agg . Sans-serif fonts is that it uses for processing. I attach a file to it all is.
These addresses have to be files with the same content.
Downloadable fonts (serif and sans-serif) font cache update.
/home/user/.matplotlib/matplotlibrc
/usr/lib/python2.5/site-packages/matplotlib/mpl-data/matplotlibrc

datapath : /usr/share/matplotlib/mpl-data
backend : Agg
font.family : serif
font.serif : Tex Gyre Termes
font.sans-serif : Arsenal
font.cursive : Tex Gyre Chorus
font.monospace : Inconsolata
text.usetex : false

and further . It should be in a folder that normally worked and preserved PNG file

Hi,

try changing backend to GTKAgg. I use only font.family option.

Put GTKagg before crashes module_path: "murrine", but now it's fine. It spent normally.

how did you deal with the fact that matplotlib is not optified?

can now answer my earlier dumb post - pymaemo-optify
