torch.resolve_neg
torch.resolve_neg(input) -> Tensor
Returns a new tensor with materialized negation if "input"'s
   negative bit is set to True, else returns "input". The output
   tensor will always have its negative bit set to False. :param
   input: the input tensor. :type input: Tensor
Example:
  >>> x = torch.tensor([-1 + 1j, -2 + 2j, 3 - 3j])
  >>> y = x.conj()
  >>> z = y.imag
  >>> z.is_neg()
  True
  >>> out = y.resolve_neg()
  >>> out
  tensor([-1, -2, -3])
  >>> out.is_neg()
  False
