HyperDriveRun Class
HyperDriveRun contains the details of a submitted HyperDrive experiment.
This class can be used to manage, check status, and retrieve run details for the HyperDrive run and each of the generated child runs.
Initialize a HyperDrive run.

HyperDriveRun
Constructor
HyperDriveRun(experiment, run_id, hyperdrive_config=None, **kwargs)
Parameters
- hyperdrive_config
- HyperDriveConfig
The configuration for this HyperDrive run. If None, we assume that the run already exists and will try to hydrate from the cloud.
Methods
cancel |
Return True if the HyperDrive run was cancelled successfully. |
fail |
Do not use. The fail method is not supported for the HyperDriveRun subclass. |
get_best_run_by_primary_metric |
Find and return the Run instance that corresponds to the best performing run amongst all child runs. The best performing run is identified solely based on the primary metric parameter specified in the HyperDriveConfig. The PrimaryMetricGoal governs whether the minimum or maximum of the primary metric is used. To do a more detailed analysis of all the ExperimentRun metrics launched by this HyperDriveRun, use get_metrics. Only one of the runs is returned, even if several of the Runs launched by this HyperDrive run reached the same best metric. |
get_children_sorted_by_primary_metric |
Return a list of children sorted by their best primary metric. The sorting is done according to the primary metric and its goal: if it is maximize, then the children are returned in descending order of their best primary metric. If reverse is True, the order is reversed. Each child in the result has run id, hyperparameters, best primary metric value and status. Children without primary metric are discarded when discard_no_metric is True. Otherwise, they are appended to the list behind other children with primary metric. Note that the reverse option has no impact on them. |
get_diagnostics |
Do not use. The get_diagnostics method is not supported for the HyperDriveRun subclass. |
get_hyperparameters |
Return the hyperparameters for all the child runs that were launched by this HyperDriveRun. |
get_metrics |
Return the metrics from all the runs that were launched by this HyperDriveRun. |
cancel
Return True if the HyperDrive run was cancelled successfully.
cancel()
Returns
Whether or not the run was cancelled successfully.

get_best_run_by_primary_metric
Find and return the Run instance that corresponds to the best performing run amongst all child runs.
The best performing run is identified solely based on the primary metric parameter specified in the HyperDriveConfig. The PrimaryMetricGoal governs whether the minimum or maximum of the primary metric is used. To do a more detailed analysis of all the ExperimentRun metrics launched by this HyperDriveRun, use get_metrics.

get_best_run_by_primary_metric(include_failed=True, include_canceled=True, include_resume_from_runs=True) -> Run | None
Parameters
Returns
The best Run, or None if no child has the primary metric.
Return type
get_children_sorted_by_primary_metric
Return a list of children sorted by their best primary metric.
The sorting is done according to the primary metric and its goal: if it is maximize, then the children are returned in descending order of their best primary metric. If reverse is True, the order is reversed.
Each child in the result has run id, hyperparameters, best primary metric value and status.
Children without primary metric are discarded when discard_no_metric is True. Otherwise, they are appended to the list behind other children with primary metric. Note that the reverse option has no impact on them.
get_children_sorted_by_primary_metric(top=0, reverse=False, discard_no_metric=False)
Parameters
- top
- int
Number of top children to be returned. If it is 0, all children will be returned.
- reverse
- bool
If it is True, the order will be reversed. It only impacts children with primary metric.
- discard_no_metric
- bool
If it is False, children without primary metric will be appended to the list.
Returns
List of dictionaries with run id, hyperparameters, best primary metric and status
Return type
get_diagnostics
Do not use. The get_diagnostics method is not supported for the HyperDriveRun subclass.
get_diagnostics()
Exceptions
get_hyperparameters
Return the hyperparameters for all the child runs that were launched by this HyperDriveRun.
get_hyperparameters()
Returns
Hyperparameters for all the child runs. It is a dictionary with run_id as key.
Return type
get_metrics
Return the metrics from all the runs that were launched by this HyperDriveRun.
get_metrics()
Returns
The metrics for all the children of this run.
