def elu(x):
    """ ELU.

    Exponential Linear Unit.

    Arguments:
        x : A `Tensor` with type `float`, `double`, `int32`, `int64`, `uint8`,
            `int16`, or `int8`

    Returns:
        A `tuple` of `tf.Tensor`. This layer inference, i.e. output Tensors
        at training and testing time.
