RestartPoolCheckpointFile ​

python
RestartPoolCheckpointFile(key_labels: tuple[str, ...], points: list[RestartPoint]) -> None

Checkpoint file holding some or all of a restart pool's points.

A resumed run restores them into its pool, so every bucket the run had reached is available from the first episode instead of waiting for the policy to re-ladder there from the start of the game. Points only: the advance windows and timeout counts are seconds to rebuild and are not saved.

Initialize the file.

Parameters:

  • key_labels (tuple[str, ...]) – The pool's bucket key labels, so a restore can refuse points keyed differently.
  • points (list[RestartPoint]) – The points to save, bucket by bucket and oldest first within a bucket.
