WebFeb 26, 2024 · Adam optimizer Pytorch Learning rate algorithm is defined as a process that plots correctly for training deep neural networks. Code: In the following code, we will import some libraries from which we get the accurate learning rate of the Adam optimizer. As of PyTorch 1.13.0, one can access the list of learning rates via the method scheduler.get_last_lr() - or directly scheduler.get_last_lr()[0] if you only use a single learning rate. Said method can be found in the schedulers' base class LRScheduler (See their code).
