When a running trial becomes stale due to the heartbeat mechanism, this callback can be used with a class in :mod:`optuna.storages` to recreate the trial in ``TrialState.WAITING`` to queue up the trial to be run again. The original stale trial can be identified by the :func:`~optuna.storages.RetryHeartbeatStaleTrialCallback.retried_trial_number` function. Even if repetitive failure occurs (a retried trial becomes stale again), this method returns the number of the original trial. To get a full list including the numbers of the retried trials as well as their original trial, call the :func:`~optuna.storages.RetryHeartbeatStaleTrialCallback.retry_history` function. This callback is helpful in environments where running trials may become stale due to external conditions, such as worker preemption or unexpected process termination. Usage: .. testcode:: import optuna from optuna.storages import RetryHeartbeatStaleTrialCallback storage = optuna.storages.RDBStorage( url="sqlite:///:memory:", heartbeat_interval=60, grace_period=120, heartbeat_stale_trial_callback=RetryHeartbeatStaleTrialCallback(max_retry=3), ) study = optuna.create_study( storage=storage, ) .. seealso:: See :class:`~optuna.storages.RDBStorage`. Args: max_retry: The max number of times a trial can be retried. Must be set to :obj:`None` or an integer. If set to the default value of :obj:`None` will retry indefinitely. If set to an integer, will only retry that many times. inherit_intermediate_values: Option to inherit `trial.intermediate_values` reported by :func:`optuna.trial.Trial.report` from the failed trial. Default is :obj:`False`.
