Research direction
Start by reproducing the AttributeError with PyTorch 1.7.1, CUDA 10.2, and Apex 0.1, then inspect the distributed-training entry point that calls _all_gather_base. Compare the available torch.distributed API with Apex's expected API; done when the compatible version or required fix is verified.
