[yt-users] error in submitting script to cluster

[Christine Simpson]

Hi,

I am trying to run yt scripts on a computing cluster that uses condor.
I have installed yt and successfully run scripts from the command line,
but I get an error when I try to submit scripts to the cluster.  I think
the problem lies in how I submit the script through condor, however, I
am trying to get a better understanding of the python error to help me
figure it out.  I was hoping you yt/python folks could give me some
insight.  

The script I'm testing out is the one that does a simple radial profile,
I copied it from the wiki:

from yt.mods import * # set up our namespace
fn= "output_0064" # parameter file to load
pf = load(fn) # load data

pc = PlotCollection(pf) # defaults to center at most dense point
pc.add_profile_sphere(50.0, "kpc", # how many of which unit at pc.center
    ["RadiusMpc", "Density"], weight="CellMassMsun", # x, y, weight
     x_bounds = (1e-3, 10.0))  # cut out zero-radius and tiny-radius
cells
    # But ... weight defaults to CellMassMsun, so we're being redundant
here!

pc.save(fn) # save all plots


I get this error:

Traceback (most recent call last):
  File "simple_radial_profile.py", line 3, in <module>

    elif path == '' or path.endswith('/'):
AttributeError: 'NoneType' object has no attribute 'endswith'

The problem is with the line that imports the yt module, but I'm not
sure exactly what the issue is.  I thought that maybe it was an issue
with not finding PYTHONPATH, but I'm not sure.

If anyone has any ideas about this error, I'd appreciate them.

Thanks
