[yt-users] X11 issues with yt

[Matthew Turk]

Hi Elizabeth,

If you're indeed running something as simple as:

mpirun -np 137 python dosomething.py

then can you try submitting a script *Without* the hashbang
/usr/bin/python at the top, and just including in it *only* the lines:

import matplotlib;matplotlib.use("Agg")

?  If that fails, then I think it's something that is out of the realm
of yt and might be cause for discussion with the sysadmins.

Good luck,

Matt
