In the last blogpost I covered how LSTM-to-LSTM networks could be used to “translate” reactants into products of chemical reactions. Additionally, it's unclear how the fast.ai flow of freeze, train, unfreeze, train work with Lightning as it appears that configure_optimizers is called once internally by the trainer. Additionally, there are new pytorch lightning model versions that are added every loop that I have to manually delete. For those not familiar, the core workflow of fast.ai goes something like this: fast.ai uses it's own system for implementing the OneCycleScheduler and it's not the most transparent system. thanks for your contribution!, great first issue! Any guidance (or a good tutorial article) would be appreciated! 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). Synonyms. Below are all the things lightning automates for you in the training loop. Sets the learning rate of each parameter group to follow a linear warmup schedule between warmup_start_lr and base_lr followed by a cosine annealing schedule between base_lr and eta_min. If women use the learning rate It guarantees tested and correct code with the best modern practices for the automated parts. My logs for ‘learning_rate’ are a constant value, the fact that they appear with the name ‘learning_rate’ instead of 'lr_adamW' like the use to tells me that the trainer has catch up the lr_scheduler but is just not calling the step method every mini batch(?) 3.
