WebJul 23, 2024 · A very good idea would be to put it just after you have defined the model. After this, you define the optimizer as optim = torch.optim.SGD (filter (lambda p: p.requires_grad, model.parameters ()), lr, momentum=momentum, weight_decay=decay, nesterov=True) and you are good to go ! Webclass torch.optim.SGD(params, lr=, momentum=0, dampening=0, weight_decay=0, nesterov=False) [source] Implements stochastic gradient descent (optionally with momentum). Nesterov momentum is based on the formula from On the importance of initialization and momentum in deep learning. Example
