WebWhen data is a tensor x, new_tensor () reads out ‘the data’ from whatever it is passed, and constructs a leaf variable. Therefore tensor.new_tensor (x) is equivalent to x.clone ().detach () and tensor.new_tensor (x, requires_grad=True) is equivalent to x.clone ().detach ().requires_grad_ (True) . The equivalents using clone () and detach ... WebAug 4, 2024 · Zero tensors are tensors whose all values are zero as shown in the below illustration.
