Hi Shankar, This is a classic error that shows up when your Python interpreter and your site-packages are compiled with different unicode on/off values. Usually it means that you're running wiht a different python interpreter than you mean to -- could you verify that the Python interpreter you're calling in the queue is the correct one? (It also looks like h5py is not being picked up, which I suspect is related to this issue.) One thing to do is to submit the queue script with an explicit path: /u/ac/sagarwal/software/enzo/src/yt/doc/yt-x86_64/bin/python2.6 hop_yt.py Another would be to make sure you're using -V as an option in your qsub script. If you're not using this, the queue system might override your PATH and PYTHONPATH environment variables in an odd way. -Matt On Fri, Jan 28, 2011 at 10:41 AM, Agarwal, Shankar <sagarwal@ku.edu> wrote:

Hi,

I am having a strange problem on Ember. When I try to run my python scripts interactively, they run fine. But when I submit them to a queue, I get the following error:

fn = "RedshiftOutput0001" pf = load(fn) halos = HaloFinder(pf,160,padding=0.02) halos.write_out("HopAnalysis.out")

pc = PlotCollection(pf,center=[0.5,0.5,0.5]) for ax in range(3):  p = pc.add_slice("Density", ax) pc.save()

Any suggestions. Shankar _______________________________________________ yt-users mailing list yt-users@lists.spacepope.org http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org
