It works, thanks! On Apr 27, 2011, at 3:07 PM, Matthew Turk wrote:
Hi Carolyn,
Skimming the source, it looks like light_ray gets imported when you do yt.analysis_modules.api. light_ray includes an import of mpi4py. So what I think is happening is that this import breaks the local MPI installation, and rather than throwing an error, it calls the system exit, dumping you back at the prompt.
I've committed what I think is a fix to both the tip and the stable repo. Can you give it a shot?

I've never had problems running YT on Ranger before, but after my latest hg pull/update I'm getting the following error:
In [3]: from yt.mods import *
In [4]: from yt.analysis_modules.api import EnzoSimulation PMGR_COLLECTIVE ERROR: unitialized MPI task: Missing required environment variable: MPIRUN_RANK
What's going on here?
Best,
