Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/56214 Pull Request resolved: https://github.com/pytorch/pytorch/pull/56037 The diff introduces new `torch.distributed.elastic_launch` and removes internals of `torch.distributed.launch` keeping backwards compatibility. Since torchelastic and torch.launch are not fully compatible due to `--use_env` arg, the `torch.distributed.launch` deprecation is going to be iterative: as part of pytorch 1.9 we are going to deprecate it, and in the following releases we will remove `torch.distributed.launch` The diff leaves `torchelastic.distributed.launch` module, and the follow up diffs will migrate the users form `torchelastic.distributed.launch` to `torch.distributed.elastic_launch` Test Plan: buck test mode/dev-nosan //pytorch/elastic/torchelastic/distributed/...
