sklearn.utils.validation.check_memory

sklearn.utils.validation.check_memory(memory)[source]

Check that memory is joblib.Memory-like.

joblib.Memory-like means that memory can be converted into a sklearn.externals.joblib.Memory instance (typically a str denoting the cachedir) or has the same interface (has a cache method).

Parameters:
memory : None, str or object with the joblib.Memory interface
Returns:
memory : object with the joblib.Memory interface
Raises:
ValueError

If memory is not joblib.Memory-like.
