WebSep 3, 2024 · The optimizer’s param_groups is a list of dictionaries which gives a simple way of breaking a model’s parameters into separate components for optimization. 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. WebMar 6, 2024 · optimizer = torch.optim.SGD (model.parameters (), lr=0.1) or similar, pytorch creates one param_group. The learning rate is accessible via param_group ['lr'] and the list of parameters is accessible via param_group ['params'] If you want different learning rates for different parameters, you can initialise the optimizer like this.
