under windows10 ProcessGroupGloo does not support reduce_scatter

Open BeGentleman opened this issue 4 years ago • 1 comments

Because of the system is Windows10. When I changed : "dist.init_process_group('nccl')" into "dist.init_process_group('gloo')"

execute the train.py under the arcface_torch dictionary. Got this Error: "RuntimeError: ProcessGroupGloo does not support reduce_scatter"

I haven't seen the other scatter support gloo, Which scatter should I use?
