Hi
I have a script to plot and save a sequence of png images which I am using to prepare animations. This works fine, but I got the following error when preparing a particularly large number of files:
— record: 1015
— record: 1016
/usr/lib/python2.5/site-packages/matplotlib/backends/backend_gtk.py:990: GtkWarning: Failed to read filechooser settings from “/home/emason/.config/gtk-2.0/gtkfilechooser.ini”: Too many open files
Traceback (most recent call last):
File “fig_bry_paper_anim_vort.py”, line 245, in
File “/usr/lib/python2.5/site-packages/matplotlib/pyplot.py”, line 271, in savefig

RuntimeError: Could not open file /home/emason/Pictures/movies/cb_3km_emb_vort_1016.png
The script is simple, below I show a pared down version of the loop where the figures are created and saved (but not shown):
for cind in Cind:
P.figure(1)
P.pcolor(plon, plat, pF[cind])
P.colorbar()
P.savefig(fname[cind], dpi=150)
P.close(1)
Does anybody know why I get this error, and can anything be done about it?
Thanks, Evan
