It allows the trainer of the model to segment the model parameters into separate units which can then be optimized at different times and with different settings.

WebDec 4, 2024 · As self.net.net is a pre-trained backbone, I only want the learning rate of this group to be 1/10 of others'. However, the learning rates of the two params groups are identified with this code. For example, both are 1e-5 at the training start, and I want them to be 1e-6 and 1e-5, respectively. Weboptimizer = torch.optim.SGD(model.parameters(), lr=learning_rate) Inside the training loop, optimization happens in three steps: Call optimizer.zero_grad () to reset the gradients of model parameters. Gradients by default add up; to prevent double-counting, we explicitly zero them at each iteration. brother bruno\u0027s pizza https://pamroy.com
