SubprocessHandler

class torch.distributed.elastic.multiprocessing.subprocess_handler.subprocess_handler.SubprocessHandler(entrypoint, args, env, stdout, stderr, local_rank_id)

Convenience wrapper around python’s subprocess.Popen. Keeps track of meta-objects associated to the process (e.g. stdout and stderr redirect fds).
