Résumé
A resumable training checkpoint also records the state needed to continue an interrupted run, and restart tests establish what it can restore.
Plongeur bu xóot
A weight checkpoint contains model parameters; a resumable training checkpoint also needs relevant optimizer, scheduler, step, random-number-generator, and data-loading state. Sharding divides large tensors or state across files and workers so saving and loading can avoid gathering everything on one rank. PyTorch Distributed Checkpoint supports distributed state saving and resharding during loading when supported by the chosen state and configuration. Sharded model weights on the Hugging Face Hub can use an index mapping parameter names to files, but weight shards alone do not capture a training run’s full progress. Applications must include their required state and validate recovery after an interrupted save or a changed environment.

Checkpoint sharding saves a large model or training state across multiple pieces for manageable storage and loading. A resumable training checkpoint also records the state needed to continue an interrupted run, and restart tests establish what it can restore.

Which extra state is typically needed for training resumption beyond model weights?
Weight shards alone do not restore optimizer history or the next intended batch. The application must save the required training progress and randomness state.

In a sharded distributed checkpoint, how can ranks avoid gathering the entire state on one worker?
Distributed checkpointing uses local state partitions and metadata. Ordinary replicated data parallelism does not automatically shard every tensor.
