phenotypic.sdk_.tune_cache_split_assignment_path#

phenotypic.sdk_.tune_cache_split_assignment_path(output_dir: Path) → Path[source]#

Return <output>/.pht-tune-cache/splits/split.json — the held-out split.

The persisted calibration / held-out partition (plate names + split kind + dataset identity + seed entropy). Read-if-exists-else-derive on resume, so a re-run reuses the original partition regardless of the new master seed. A legacy run wrote it under <output>/splits/; use resolve_split_assignment_path() to read either location.

Parameters:

output_dir (Path) – The run output directory.

Returns:

<output_dir>/.pht-tune-cache/splits/split.json.

Return type:

Path
