tf.compat.v1.tanh

Used in the notebooks

Given an input tensor, this function computes hyperbolic tangent of every element in the tensor. Input range is [-inf, inf] and output range is [-1,1].

  x = tf.constant([-float("inf"), -5, -0.5, 1, 1.2, 2, 3, float("inf")])
  tf.math.tanh(x)
    <tf.Tensor: shape=(8,), dtype=float32, numpy=
    array([-1.0, -0.99990916, -0.46211717,  0.7615942 ,  0.8336547 ,

x A Tensor. Must be one of the following types: bfloat16, half, float32, float64, complex64, complex128.
name A name for the operation (optional).

A Tensor. Has the same type as x.

If x is a SparseTensor, returns SparseTensor(x.indices, tf.math.tanh(x.values, ...), x.dense_shape)
