Retrieve names of namedtuple output

I wonder if it’s possible to retrieve the names of the resulting output when calling a traced function, for example:

import torch
from collections import namedtuple
output = namedtuple("output", ["hello", "bye"])

def f (x):
  return output(x, 2*x)

traced_fn = torch.jit.trace(f, torch.tensor(1))

Returns an unamed tuple:

(tensor(2), tensor(4))

I know I can return a dictionary and disable strict, to get named outputs but would like to know if this this possible with named tuples.
