AttributeError: module 'torch._C' has no attribute '_dist_init_process_group'

I get the above mentioned error when I try to run the followed code:

import torch.distributed
import ipdb

if name == ‘main’:
ipdb.set_trace()
torch.distributed.init_process_group(backend=‘mpi’)
rank = torch.distributed.collectives.get_rank()

print('My rank is ' + rank)

I am running this code on command line as follows:
mpiexec -n 2 python main.py

torch.distributed is still alpha quality and you can expect weird broken builds.

we will announce when it’s ready.

Thank you for your reply.

Does it mean that I should update my installed package to get a working version? Or the package torch.distributed is not functional yet in which case I will wait for your announcement.
