I am trying to access a shared library with OpenMPI via python, but for some reason I get the following error message:
[Geo00433:01196] mca: base: component_find: unable to open /usr/li/openmpi/lib/openmpi/mca_paffinity_hwloc: perhaps a missing symbol, or compiled for a different version of Open MPI? (ignored)

It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here is some additional information (which may only be relevant to an
Open MPI developer):
opal_shmem_base_select failed
--> Returned value -1 instead of OPAL_SUCCESS

[Geo00433:1196] Local abort before MPI_INIT completed successfully; not able to aggregate error messages, and not able to guarantee that all other processes were killed!
Any clue what's the reason? I checked many webpages already, but somehow couldn't find a solution for my problem yet.
I have Ubuntu 15.10 and mpich as well as open-mpi installed.
Thanks a lot guys!
