Primary algorithm¶

TODO

Utility function for creating and wrapping the HPO algorithm.

orion.core.worker.primary_algo.create_algo(algo_type: Callable[[Space, P], AlgoT], space: Space, knowledge_base: None = None, *algo_args: P.args, **algo_kwargs: P.kwargs) → InsistSuggest[SpaceTransform[AlgoT]][source]¶

orion.core.worker.primary_algo.create_algo(algo_type: Callable[[Space, P], WarmStarteableAlgoT], space: Space, knowledge_base: KnowledgeBase, *algo_args: P.args, **algo_kwargs: P.kwargs) → InsistSuggest[SpaceTransform[WarmStarteableAlgoT]]

orion.core.worker.primary_algo.create_algo(algo_type: Callable[[Space, P], AlgoT], space: Space, knowledge_base: KnowledgeBase, *algo_args: P.args, **algo_kwargs: P.kwargs) → MultiTaskWrapper[InsistSuggest[SpaceTransform[AlgoT]]]

Adds different wrappers on top of an algorithm of type algo_type before it gets used.

These wrappers are used to: - apply the transformations required for the algorithm to be applied to the given search space; - If a knowledge base is passed, and the algorithm isn’t warmstarteable, the algo is wrapped

with a MultiTaskWrapper;

Make sure that calls to returned algo’s suggest method returns a Trial, by trying a few times.

Parameters

algo_type: Type of algorithm to create and wrap.
space: The (original, un-transformed) search space.
knowledge_base: The Knowledge base to use for warm-starting of the algorithm, by default None.

Returns

An AlgoWrapper around the algorithm of type algo_type.
