Hi, teachers
code:

import numpy as np
from mpi4py import MPI
comm = MPI.COMM_WORLD
rank = comm.Get_rank()
print("rank",rank)
if __name__ == '__main__':
if rank == 0:
mem = np.array([0], dtype='i')
win = MPI.Win.Create(mem, comm=comm)
else:
win = MPI.Win.Create(None, comm=comm)
print(rank, "end")
(py3.6.8) ➜ ~ mpirun -n 2 python -u test.py
rank 0
rank 1
