you need to call MPI_Finalize somehow?
Maybe you need to explicitly close the MPI module (which then implicitly calls
MPI_Finalize)? I'm afraid I don't know much about mpi4py, so I can't offer
specific advice.

Well, not sure what I can advise. Check to ensure that your LD_LIBRARY_PATH
is pointing to the same installation where your mpirun is located. For
whatever reason, the processes think they are singletons - i.e., that they
were not actually started by mpirun.
You might also want to ask the mpi4py f

I don't think that is true, but I suggest you check the mpi4py examples. I
believe all import does is import function definitions - it doesn't execute
anything.

The usual reason for this is that you aren't launching these processes
correctly. How are you starting your job? Are you using mpirun?

Yes - that is precisely the behavior y
Yes you are right this is what it says but if fact the weird thing is that not
all times the error message appears….I send to 20 nodes and only one gives this
message, is this normal…

Well, as it says, your processes called MPI_Init, but at least one of them
exited without calling MPI_Finalize. That violates the MPI rules and we
therefore terminate the remaining processes.
Check your code and see how/why you are doing that - you probably have a code
path whereby a process ex
