WebFeb 5, 2024 · In PyTorch, creating a custom optimizer is a two-step process. First, we need to create a class that inherits from the torch.optim.Optimizer class, and override the following methods: __init__ (self, params): This method is used to initialize the optimizer and store the model parameters in the params attribute. WebA LightningModule organizes your PyTorch code into 6 sections: Initialization ( __init__ and setup () ). Train Loop ( training_step ()) Validation Loop ( validation_step ()) Test Loop ( test_step ()) Prediction Loop ( predict_step ()) Optimizers and LR Schedulers ( configure_optimizers ())
