you can add `os.environ['GLOO_SOCKET_IFNAME'] = 'eno1'` in train_net.py. like this: ``` if __name__ == "__main__": args = default_argument_parser().parse_args() print("Command Line Args:", args) os.environ['GLOO_SOCKET_IFNAME'] = 'eno1' launch( main, args.num_gpus, num_machines=args.num_machines, machine_rank=args.machine_rank,...

You can use `pip install psutil` to solve it.
