module documentation
Helper to integrate modular pipelines into a master pipeline.
Exception |
|
Raised when a modular pipeline is not adapted and integrated appropriately using the helper. |
Function | _get |
Take a name or a collection of dataset names and turn it into a mapping from the old dataset names to the provided ones if necessary. |
Function | _get |
Take a parameter or a collection of parameter names and turn it into a mapping from existing parameter names to new ones if necessary. It follows the same rule as _get_dataset_names_mapping and prefixes the keys on the resultant dictionary with ... |

¶
Take a name or a collection of dataset names and turn it into a mapping from the old dataset names to the provided ones if necessary.
Examples
>>> _get_dataset_names_mapping("dataset_name") {"dataset_name": "dataset_name"} # a str name will stay the same >>> _get_dataset_names_mapping(set(["ds_1", "ds_2"])) {"ds_1": "ds_1", "ds_2": "ds_2"} # a Set[str] of names will stay the same >>> _get_dataset_names_mapping({"ds_1": "new_ds_1_name"}) {"ds_1": "new_ds_1_name"} # a Dict[str, str] of names will map key to value
Parameters | |
names:Union[ | A dataset name or collection of dataset names. When str or Set[str] is provided, the listed names will stay the same as they are named in the provided pipeline. When Dict[str, str] is provided, current names will be mapped to new names in the resultant pipeline. |
Returns | |
Dict[ | A dictionary that maps the old dataset names to the provided ones. |
def _get_param_names_mapping(names:
Union[ str, Set[ str], Dict[ str, str]]
= None) -> Dict[ str, str]
:
(source)
¶
Take a parameter or a collection of parameter names
and turn it into a mapping from existing parameter names to new ones if necessary.
It follows the same rule as _get_dataset_names_mapping
and
prefixes the keys on the resultant dictionary with params:
to comply with node's syntax.
Examples
>>> _get_param_names_mapping("param_name") {"params:param_name": "params:param_name"} # a str name will stay the same >>> _get_param_names_mapping(set(["param_1", "param_2"])) # a Set[str] of names will stay the same {"params:param_1": "params:param_1", "params:param_2": "params:param_2"} >>> _get_param_names_mapping({"param_1": "new_name_for_param_1"}) # a Dict[str, str] of names will map key to valu {"params:param_1": "params:new_name_for_param_1"}
Parameters | |
names:Union[ | A parameter name or collection of parameter names. When str or Set[str] is provided, the listed names will stay the same as they are named in the provided pipeline. When Dict[str, str] is provided, current names will be mapped to new names in the resultant pipeline. |
Returns | |
Dict[ | A dictionary that maps the old parameter names to the provided ones. |
