Top level function: given a lale operator, returns a list of hp grids.

Parameters

• op (The lale PlannedOperator) –

• num_grids (integer or float, optional) – if set to an integer => 1, it will determine how many parameter grids will be returned (at most) if set to an float between 0 and 1, it will determine what fraction should be returned note that setting it to 1 is treated as in integer. To return all results, use None

• pgo (Optional Profile Guided Optimization data that can be used when discretizing continuous parameters) –

• data_schema (A schema for the actual data. If provided, it is used to instantiate data dependent schema hyperamparameter specifications.) –
