deephyper.search.nas.NeuralArchitectureSearch

class deephyper.search.nas.NeuralArchitectureSearch(problem, evaluator, random_state=None, log_dir='.', verbose=0, **kwargs)

Bases: deephyper.search._search.Search

Methods

check_evaluator
dump_context	Dumps the context in the log folder.
search	Execute the search algorithm.
to_json	Returns a json version of the search object.

dump_context()

Dumps the context in the log folder.

search(max_evals: int = - 1, timeout: Optional[int] = None)

Execute the search algorithm.

Parameters

• max_evals (int, optional) – The maximum number of evaluations of the run function to perform before stopping the search. Defaults to -1, will run indefinitely.

• timeout (int, optional) – The time budget (in seconds) of the search before stopping. Defaults to None, will not impose a time budget.

Returns

a pandas DataFrame containing the evaluations performed or None if the search could not evaluate any configuration.

Return type

DataFrame

to_json()
