fiftyone.core.selection#
Exact episode and segment membership shared by selections and saved subsets.
Functions:
|
Validates and deduplicates members without merging overlapping ranges. |
|
Returns a canonical identity excluding provenance and dataset scope. |
|
Clips candidates to an explicit subset boundary on time and streams. |
|
Selects parents by id, reaching into every slice of a grouped dataset. |
|
Groups stored members without changing full/segment coexistence. |
|
Counts parent episodes separately from full-episode and segment units. |
- fiftyone.core.selection.normalize_members(members)#
Validates and deduplicates members without merging overlapping ranges.
Bounds are decimal integers on a named native timebase. Frame events use zero-based, half-open sequence bounds; nanosecond sources retain their exact integer precision. Stream sets are resolved before capture.
- Parameters:
members – an iterable of episode/segment dictionaries
- Returns:
the normalized members, with combined provenance for duplicates
- fiftyone.core.selection.member_key(member)#
Returns a canonical identity excluding provenance and dataset scope.
Storage always pairs this identity with a dataset ID and subset ID.
- fiftyone.core.selection.intersect_members(candidates, allowed)#
Clips candidates to an explicit subset boundary on time and streams.
Whole-episode membership admits either scope. Segment-only membership cannot admit a full-episode candidate. Distinct saved intervals remain distinct even when overlapping.
- fiftyone.core.selection.select_parents(collection, ids)#
Selects parents by id, reaching into every slice of a grouped dataset.
- fiftyone.core.selection.group_members(members, samples=None)#
Groups stored members without changing full/segment coexistence.
- fiftyone.core.selection.count_members(members, unavailable_ids=())#
Counts parent episodes separately from full-episode and segment units.
