WebJan 18, 2024 · Here, we will set the requires_grad parameter to be True which will automatically compute the gradients for us. x = torch.tensor ( [ 1., -2., 3., -1. ], requires_grad= True) Code language: PHP (php) Next, we will apply the torch.relu () function to the input vector X. The ReLu stands for Rectified Linear Activation Function. WebTensor and Function are interconnected and build up an acyclic graph, that encodes a complete history of computation. Each variable has a .grad_fn attribute that references a function that has created a function (except for Tensors created by the user - these have None as .grad_fn ).
