  Given a tensor `x` of complex numbers, this operation returns a tensor of type
  `float32` or `float64` that is the absolute value of each element in `x`. For
  - a complex number \\(a + bj\\), its absolute value is computed as \\(\sqrt{a^2
  - + b^2}\\). For example:
  + a complex number \\(a + bj\\), its absolute value is computed as
  + \\(\sqrt{a^2 + b^2}\\). For example:
  >>> x = tf.constant([[-2.25 + 4.75j], [-3.25 + 5.75j]])
  >>> tf.abs(x)
