[yt-users] X11 issues with yt

[Elizabeth Tasker]

Hi,

I suspect this is really a python query, but I've been unable to fix 
it... An cluster upgrade has meant I have to submit all my yt scripts to 
the queue, rather than running interactively. For some reason, my script 
wants to pull up a window to show its plot and then panics because it 
can't find a display when it's submitted to a node. I don't understand 
why it wants to do this when I ask it to save, not show:



from yt.config import ytcfg; ytcfg["yt","serialize"] = "False"
from yt.analysis_modules.api import EnzoSimulation as ES
from yt.mods import *
.
.
.
.
stuff
.
.
.
pylab.plot(time, mass)
pylab.ylim([6.39e9, 6.5e9])
pylab.savefig("mass_fig.png")


I tried adding a "matplotlib.use('agg')" in there but to no avail.
