Webtransformers.get_constant_schedule_with_warmup (optimizer: torch.optim.optimizer.Optimizer, num_warmup_steps: int, last_epoch: int = - 1) [source] ¶ Create a schedule with a constant learning rate preceded by a warmup period during which the learning rate increases linearly between 0 and the initial lr set in the optimizer. … WebLinear Warmup With Cosine Annealing. Edit. Linear Warmup With Cosine Annealing is a learning rate schedule where we increase the learning rate linearly for n updates and then anneal according to a cosine schedule afterwards.

Decays the learning rate of each parameter group by linearly changing small multiplicative factor until the number of epoch reaches a pre-defined milestone: total_iters. Notice that such decay can happen simultaneously with other changes to the learning rate from outside this scheduler. When last_epoch=-1, sets initial lr as lr. system online roborough
