WebAug 16, 2024 · In brief, gradient checkpointing is a trick to save memory by recomputing the intermediate activations during backward. Think of it like “lazy” backward. Layer activations are not saved for backpropagation but recomputed when necessary. To use it in pytorch: That looks surprisingly simple. WebDec 6, 2024 · To compute the gradients, a tensor must have its parameter requires_grad = true.The gradients are same as the partial derivatives. For example, in the function y = 2*x + 1, x is a tensor with requires_grad = True.We can compute the gradients using y.backward() function and the gradient can be accessed using x.grad.. Here, the value …
