Python _inv_grad Examples

Example #1

def _InvGradGrad(op, grad):
  b = op.inputs[1]
  # op.output[0]: y = -b * conj(a)^2
  with ops.control_dependencies([grad.op]):
    ca = math_ops.conj(op.inputs[0])
    cg = math_ops.conj(grad)
    # pylint: disable=protected-access
    return cg * -2.0 * b * ca, gen_math_ops._inv_grad(ca, grad)

Example #2
