Dear all,
I have a module written by myself which use
python-netcdf/matplotlib/numpy/basemap for treating and mapping of netcdf
files.
so in the module I have a line:
import matplotlib.pyplot as plt
But now I am using some function of this module which do not involve the
visualisation. And I want to use it in a batch mode submitted by qsub
command.
And then I have traceback like following:
File "/home/orchidee01/ychao/SCRIPT/combine.py", line 1, in <module>
import gnc
File "/home/users/ychao/python/python_lib/gnc.py", line 4, in <module>

52, in _init
_gtk.init_check()
RuntimeError: could not open display
>From the last line, I think this is because I cannot use this module in a
non-interactive mode. So is there a way I can bypass this issue and still
use the module in a non-interactive mode? Thanks a lot for any information.
