tf.compat.v1.raw_ops.SparseSoftmaxCrossEntropyWithLogits

tf.raw_ops.SparseSoftmaxCrossEntropyWithLogits(
    features, labels, name=None
)

Unlike SoftmaxCrossEntropyWithLogits, this operation does not accept a matrix of label probabilities, but rather a single label per row of features. This label is considered to have probability 1.0 for the given row.

Inputs are the logits, not probabilities.

Args
features	A Tensor. Must be one of the following types: half, bfloat16, float32, float64. batch_size x num_classes matrix
labels	A Tensor. Must be one of the following types: int32, int64. batch_size vector with values in [0, num_classes). This is the label for the given minibatch entry.
name	A name for the operation (optional).

Returns
A tuple of Tensor objects (loss, backprop).
loss	A Tensor. Has the same type as features.
backprop	A Tensor. Has the same type as features.
