phenotypic.tune.infer_search_space

phenotypic.tune.infer_search_space(pipeline: Any, *, unbounded_factor: float = 4.0, recurse_nested: bool = True) → InferredSearchSpace

Mine a pipeline into a generous, reviewable InferredSearchSpace.

Walks the pipeline’s ops in position order and infers each scalar field via the Tier-2 type heuristics (Tier-1 TuneSpec override added in P3-4). Knob keys are flat "<position>.<field>" paths.

Parameters:

• pipeline (Any) – A live ImagePipeline whose get_ops() yields the ops in insertion order.

• unbounded_factor (float) – Multiplicative half-window [d/f, d·f] for the unbounded numeric heuristic (default 4.0 → 16× span).

• recurse_nested (bool) – Recurse exactly one level into operation-valued (OperationField) fields — a single nested op or a list of them. On by default; False yields the flat-only proposal (no nested knobs), byte-identical to the pre-recursion space. The recursion is strictly additive: a pipeline with no nested ops is unchanged.

Returns:

The InferredSearchSpace proposal.

Return type:
