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 … Web🚧 1 fixed upstream failure:. These were probably caused by upstream breakages that were already fixed.. Please rebase on the viable/strict branch (expand for instructions) . If your commit is older than viable/strict, run these commands:
