Test the model on a single batch of samples.
Keras model object
Input data. Must be array-like.
Target data. Must be array-like.
Optional array of the same length as x, containing weights to apply to the model's loss for each sample. In the case of temporal data, you can pass a 2D array with shape
(samples, sequence_length), to apply a different weight to every timestep of every sample.
for forward/backward compatability
A scalar loss value (when no metrics), or a named list of loss and metric values (if there are metrics).
