tf.compat.v1.math.log_softmax, tf.compat.v1.nn.log_softmax

tf.nn.log_softmax(
    logits, axis=None, name=None, dim=None
)

For each batch i and class j we have

logsoftmax = logits - log(reduce_sum(exp(logits), axis))

Args
logits	A non-empty Tensor. Must be one of the following types: half, float32, float64.
axis	The dimension softmax would be performed on. The default is -1 which indicates the last dimension.
name	A name for the operation (optional).
dim	Deprecated alias for axis.

Returns
A Tensor. Has the same type as logits. Same shape as logits.

Raises
InvalidArgumentError	if logits is empty or axis is beyond the last dimension of logits.
