This is often indicative of a mismatched MPI library and mpiexec 
launcher. Take care to ensure that the MPI library linked to your binary 
and mpiexec are (ideally) part of the same installation.

This is supposed to run on 5 processes (that is what happening on local machine). But on cluster it keeps running it with 1 process. I have tried mpi4py but apparently it has conflict. I was wondering if you have any idea how to fix this.
