albanD:

b = a in python actually gives you the same Tensor. So there is nothing to “record”.
If you do a clone, you get a new Tensor (object and memory)


Ah! That’s useful, thanks! a=b are exactly the same while c vs a are not.
But the underlying memory the share is the same, right? So in effect it looks like they are truly the same except that python isn’t aware of it…right?
