AttributeError: type object 'torch.distributed.ReduceOp' has no attribute 'BAND'

Reproduce the failure from interact.py through train.py, then inspect the installed Ignite files at ignite/distributed/comp_models/native.py and the torch.distributed.ReduceOp API. Determine the compatible dependency behavior and verify that importing ignite no longer raises the ReduceOp.BAND AttributeError.
