tf.keras.metrics.sparse_categorical_crossentropy

Computes the sparse categorical crossentropy loss.

Used in the guide

Standalone usage:

````y_true = [1, 2]`
`y_pred = [[0.05, 0.95, 0], [0.1, 0.8, 0.1]]`
`loss = tf.keras.losses.sparse_categorical_crossentropy(y_true, y_pred)`
`assert loss.shape == (2,)`
`loss.numpy()`
`array([0.0513, 2.303], dtype=float32)`
```

`y_true` Ground truth values.
`y_pred` The predicted values.
`from_logits` Whether `y_pred` is expected to be a logits tensor. By default, we assume that `y_pred` encodes a probability distribution.
`axis` Defaults to -1. The dimension along which the entropy is computed.
