Get summary lineage from data_manager or parsing from summaries.
One of data_manager or summary_dir needs to be specified. Support getting
super_lineage_obj from data_manager or parsing summaries by summary_dir.
Args:
data_manager (DataManager): Data manager defined as
mindinsight.datavisual.data_transform.data_manager.DataManager
summary_dir (str): The summary directory. It contains summary logs for
one training.
keys (list[str]): The filter keys of lineage information. The acceptable
keys are `metric`, `user_defined`, `hyper_parameters`, `algorithm`,
`train_dataset`, `model`, `valid_dataset` and `dataset_graph`.
If it is `None`, all information will be returned. Default: None.
Returns:
dict, the lineage information for one training.
Raises:
LineageParamSummaryPathError: If summary path is invalid.
LineageQuerySummaryDataError: If querying summary data fails.
LineageFileNotFoundError: If the summary log file is not found.
