Hi, teachers
code:
import mpi4py
import time
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")

Why is this happening? How to debug? This error is not reported on the other
machine.
