Examples

>>> import paddle.distributed as dist
>>> placements = [dist.Replicate(), dist.Shard(0), dist.Partial()]
>>> for p in placements:
>>>     if isinstance(p, dist.Placement):
>>>         if p.is_replicated():
>>>             print("replicate.")
>>>         elif p.is_shard():
>>>             print("shard.")
>>>         elif p.is_partial():
>>>             print("partial.")
