phenotypic.sdk_.tune_cache_study_db_path

phenotypic.sdk_.tune_cache_study_db_path(output_dir: Path) → Path

Return <output>/.pht-tune-cache/study.db (the Optuna study DB).

Parameters:

output_dir (Path) – The run output directory.

Returns:

<output_dir>/.pht-tune-cache/study.db.

Return type:

Path
