Description Stefan Seefeld 2015-10-18 04:13:15 UTC 
I just installed the mpi4py-openmpi package to use mpi4py (using OpenMPI as backend) in Python. It isn't entirely clear how I'm supposed to use that module.
I'd expected to be able to just use 'python -c "import mpi4py"', but that doesn't work as there is no 'mpi4py' module. Rather, the package installs what looks like 'openmpi.mpi4py'. However, 'python -c "import openmpi.mpi4py"' doesn't work either, because the 'openmpi' directory within my Python module tree doesn't contain a __init__.py file. If I add that file (empty), I'm at least able to run 'python -c "import openmpi.mpi4py"', though I still am not sure what to do with it. Shouldn't there be a toplevel 'mpi4py' module that then dispatches to a suitable backend (such as openmpi or mpich2) depending on which of the backends is installed ?

Thanks for your help.

You need to load the openmpi 'module' first.

Could you try to load e.g. "mpi/openmpi" within the shell, you are using?
