This function creates a synchronous checkpointer with default components, automatically detecting rank information from the default process group if available, and using the provided component configurations. Args: config: CheckpointerConfig containing component-specific configurations (writer_config, staging_config, process_config). Defaults to CheckpointerConfig(). rank_info: RankInfo for distributed training. Defaults to auto-detection from the default PyTorch distributed process group if initialized, otherwise falls back to single-rank (world_size=1, rank=0). commit_hook: Optional hook for custom actions before and after checkpoint commits. Returns: SyncCheckpointer: A configured synchronous checkpointer instance. Examples: # Simplest usage - auto-detect rank, default config checkpointer = make_sync_checkpointer() # Explicit rank configuration checkpointer = make_sync_checkpointer( rank_info=RankInfo(global_world_size=4, global_rank=0) ) # Disable barrier from .barriers import BarrierConfig config = CheckpointerConfig(barrier_config=BarrierConfig(barrier_type=None)) checkpointer = make_sync_checkpointer(config=config) r#)r"r barrierr%)writerreader)rrrbarrier_configr writer_configr )r"r r%r)r'r(s rmake_sync_checkpointerr,6scJ*, F))>)>?G ## F  rrsubprocess_init_fn).Nsubprocess_init_args.checkpoint_writer_init_fncheckpoint_writer_init_argsc Uc [5n[US9n[URS9nU=(d 0n[ UUR UUUUS9n[ UUUS9$)a# Factory function to create an AsyncCheckpointer instance with sensible defaults.
