Description

I have problems getting mpi4py to work in macports 

$ port installed | grep -i mpi
  mpich2 @1.4.1p1_0 (active)
  py27-mpi4py @1.2.2_1 (active)

I get the following error when importing 

$ /opt/local/bin/mpirun -n 1 python test.py 
Traceback (most recent call last):
  File "test.py", line 72, in <module>
    from mpi4py import MPI

I cannot install nor test mpich2 because all my tools are openmpi-related.

My understanding is that mpich2 is deprecated these days in favour of openmpi.

Can you uninstall mpich2 and upgrade your mpi4py? It should use openmpi by default now.
