destroy_vni_context(1137).......: OFI domain close failed (ofi_init.c:1137:destroy_vni_context:Devic

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")

(py3.6.8) ➜ ~ mpirun -n 2 python -u test.py
rank 0
rank 1
0 end
1 end

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