sklearn.utils.validation.check_memory

sklearn.utils.validation.check_memory(memory)

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.
