Type specification for tf.experimental.Optional.

Inherits From: TypeSpec

For instance, tf.OptionalSpec can be used to define a tf.function that takes tf.experimental.Optional as an input argument:

  tf.TensorSpec(shape=(), dtype=tf.int32, name=None))])
def maybe_square(optional):
  if optional.has_value():
    x = optional.get_value()
    return x * x
  return -1
optional = tf.experimental.Optional.from_value(5)
tf.Tensor(25, shape=(), dtype=int32)

element_spec A nested structure of TypeSpec objects that represents the type specification of the optional element.
value_type The Python type for values that are compatible with this TypeSpec.

In particular, all values that are compatible with this TypeSpec must be an instance of this type.
