.SqlStorage¶
- class mlos_bench.storage.sql.storage.SqlStorage(config: dict, global_config: dict | None = None, service: Service | None = None)¶
An implementation of the Storage interface using SQLAlchemy backend.
- Attributes:
experiments
Retrieve the experiments’ data from the storage.
Methods
Experiment
(*, tunables, experiment_id, ...)Base interface for storing the results of the experiment.
Trial
(*, tunables, experiment_id, trial_id, ...)Base interface for storing the results of a single run of the experiment.
experiment
(*, experiment_id, trial_id, ...)Create a new experiment in the storage.
- __init__(config: dict, global_config: dict | None = None, service: Service | None = None)¶
Create a new storage object.
- Parameters:
- configdict
Free-format key/value pairs of configuration parameters.
- experiment(*, experiment_id: str, trial_id: int, root_env_config: str, description: str, tunables: TunableGroups, opt_targets: Dict[str, Literal['min', 'max']]) Experiment ¶
Create a new experiment in the storage.
We need the opt_target parameter here to know what metric to retrieve when we load the data from previous trials. Later we will replace it with full metadata about the optimization direction, multiple objectives, etc.
- Parameters:
- experiment_idstr
Unique identifier of the experiment.
- trial_idint
Starting number of the trial.
- root_env_configstr
A path to the root JSON configuration file of the benchmarking environment.
- descriptionstr
Human-readable description of the experiment.
- tunablesTunableGroups
- opt_targetsDict[str, Literal[“min”, “max”]]
Names of metrics we’re optimizing for and the optimization direction {min, max}.
- Returns:
- experimentStorage.Experiment
An object that allows to update the storage with the results of the experiment and related data.
- property experiments: Dict[str, ExperimentData]¶
Retrieve the experiments’ data from the storage.
- Returns:
- experimentsDict[str, ExperimentData]
A dictionary of the experiments’ data, keyed by experiment id.
