tf.keras.backend.sparse_categorical_crossentropy(
    target, output, from_logits=False, axis=-1
)

Arguments
target	An integer tensor.
output	A tensor resulting from a softmax (unless from_logits is True, in which case output is expected to be the logits).
from_logits	Boolean, whether output is the result of a softmax, or is a tensor of logits.
axis	Int specifying the channels axis. axis=-1 corresponds to data format channels_last', andaxis=1corresponds to data formatchannels_first`.

Returns
Output tensor.

Raises
ValueError	if axis is neither -1 nor one of the axes of output.
