If you use the learning rate scheduler (calling scheduler.step()) before the optimizer’s update (calling optimizer.step()), this will skip the first value of the learning rate schedule.

WebJul 16, 2024 · For Warmup step number, specify how many epochs you'd like to warm up the training, in case initial learning rate is slightly too large to start converging, by default 0. For Learning rate, specify a value for the learning rate, and the default value is 0.001. Learning rate controls the size of the step that is used in optimizer like sgd each ...

WebJul 19, 2024 · I looked around in different forums but couldn’t find a satisfactory answer. Side note: I’d like the final learning rate to be 3e-5 after the warmup so I set the initial LR as 3e-5 and end_factor as 1 with initial factor being 0.05. This results in the final lr after warm up to be 1.5e-6 which is off by a factor of 20. WebWarmupCosineSchedule: Linearly increases learning rate from 0 to 1 over warmup fraction of training steps. Decreases learning rate from 1. to 0. over remaining 1 - warmup steps following a cosine curve. If cycles (default=0.5) is different from default, learning rate follows cosine function after warmup.

WebWhen using custom learning rate schedulers relying on a different API from Native PyTorch ones, you should override the lr_scheduler_step () with your desired logic. If you are using native PyTorch schedulers, there is no need to override this hook since Lightning will handle it automatically by default. WebOct 28, 2024 · The learning rate is increased linearly over the warm-up period. If the target learning rate is p and the warm-up period is n, then the first batch iteration uses 1 p/n for its learning rate; the second uses 2 p/n, and so on: iteration i uses i*p/n, until we hit the nominal rate at iteration n.
