How to run python script with mpi4py (using mpiexec) from within pycharm?

Ask Time：2019-08-16T13:08:25 Author：Amr ALHOSSARY

I have a python script that depends on mpi4py implementation of MPI. This needs to be run through mpiexec (or mpirun).

My Question is : How to run (and hopefully debug) a python script using mpiexec (or mpirun) from PyCharm directly?

Running mpiexec as an external tool is not a good idea, because I will not be able to debug it.

What can I do instead?
