Could you try the line above and confirm whether it hangs?

Use maxprocs=1 and make different spawn calls.
However, I have to insist. If you are using mpi4py as a tool to spawn
a bunch of different processes that work in isolation and then collect
result at the end, then mpi4py is likely not the right tool for the
task, at least if you do not have previous experience with MPI
programming.
