WebUnder the hood, to prevent reference cycles, PyTorch has packed the tensor upon saving and unpacked it into a different tensor for reading. Here, the tensor you get from accessing y.grad_fn._saved_result is a different tensor object than y (but they still share the same storage).. Whether a tensor will be packed into a different tensor object depends on …
