Hello,

I would like to know if it is possible to transfer the `.grad`

attribute of a tensor, e.g, **y** to a **z** tensor which does not have one.

To simplify my problem:

import torch

x = torch.ones(2, 2, requires_grad=True)

y= x + 2

z= tensor([[3, 3], [3, 3]])

I would like then to transfer **y**.grad_fn to **z**. More specifically I want to, in a way, save grad_fn of a tensor and give it later to a new tensor.

Thank you in advance.

Best regards,
