IMPORT PROBLEM

[Mahan Raj Banerjee]

Hello

I have installed mpi4py-1.3 with ETD-7.2-1 in my system (Fedora 16). But whenever I try to import MPI from mpi4py in ipython console I get the following message:

"ImportError: libmpi.so.0: cannot open shared object file: No such file or directory"

Please help

I have openmpi-1.4.5 installed in my system.

Where is libmpi.so.0 on your system?  Is it on your LD_LIBRARY_PATH?  I seem to recall that Fedora uses modules to handle MPI installations in a fairly wonky manner.

mpi4py is also available in the Fedora repository, so it would probably best to install it from there with:

"yum install mpi4py-openmpi"

or

"yum install mpi4py-mpich2"

After loading the proper mpi environment with e.g. "module load openmpi-x86_64" you should be able to use mpi4py out of the box.

However, IIUC, the OP want to use mpi4py with EPD Python distribution.
So perhaps building mpi4py is still required. Anyway, I expect that
installing mpi4py from Fedora repos and adding a symlink to EPD's
site-packages directory would work.
