Learning rate warm up pytorch

Nettet19. jul. 2024 · 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. I don’t quite understand why this happens, help on that would also be appreciated. Thanks.
