Research direction
Start by reproducing the AttributeError in Apex with DistributedDataParallel and delay_allreduce disabled. Trace the access to buckets_ready_size through the distributed-training path and determine the expected behavior for this configuration; done means the error no longer occurs and the behavior is covered by a regression check.
