In PyTorch 1.1.0 and later, you should call them in the opposite order: `optimizer.step()` before `lr_scheduler.step()`. Failure to do this will result in PyTorch skipping the first value of the learning rate schedule.

http://www.iotword.com/3023.html WebJul 27, 2024 · Now let us take a look at the learning rate scheduler in PyTorch in a little more detail. The learning rate scheduler has to be used by first creating an optimizer object in the working environment. The object created should have the ability to take in the current state of the models and be responsible for updating the parameters based on the computed …
http://www.iotword.com/5638.html WebJan 31, 2024 · Use optimizer.step () before scheduler.step (). Also, for OneCycleLR, you need to run scheduler.step () after every step - source (PyTorch docs). So, your training code is correct (as far as calling step () on optimizer and schedulers is concerned).
WebMay 9, 2024 · 8. TL;DR: The LR scheduler contains the optimizer as a member and alters its parameters learning rates explicitly. As mentioned in PyTorch Official Documentations, the learning rate scheduler receives the optimizer as a parameter in its constructor, and thus … WebNeed for Learning Rate Schedules Benefits Converge faster Higher accuracy Top Basic Learning Rate Schedules Step-wise Decay Reduce on Loss Plateau Decay Step-wise Learning Rate Decay Step-wise Decay: Every Epoch At every epoch, ηt =ηt−1γ η t = η t − 1 γ γ = 0.1 γ = 0.1 Optimization Algorithm 4: SGD Nesterov Modification of SGD Momentum
