pescador.maps.keras_tuples(stream, inputs=None, outputs=None)¶

Reformat data objects as keras-compatible tuples.

Parameters:

streamiterable: Stream of data objects.
inputsstring or iterable of strings, None: Keys to use for ordered input data. If not specified, returns None in its place.
outputsstring or iterable of strings, default=None: Keys to use for ordered output data. If not specified, returns None in its place.

Yields:

xnp.ndarray, list of np.ndarray, or None: If inputs is a string, x is a single np.ndarray. If inputs is an iterable of strings, x is a list of np.ndarrays. If inputs is a null type, x is None.
ynp.ndarray, list of np.ndarray, or None: If outputs is a string, y is a single np.ndarray. If outputs is an iterable of strings, y is a list of np.ndarrays. If outputs is a null type, y is None.

Raises:
