WebJan 26, 2024 · The gradients of the loss with respect to the weight parameter of the Linear module are added to net.weight.grad. Note that running loss.backward () does not replace the gradients stored in net.weight.grad and net.bias.grad, it adds the new gradients to the gradients that are already there. Hence the use of the term “accumulated”.
