Pytorch warmup learning rate
WebApr 20, 2024 · This post uses PyTorch v1.4 and optuna v1.3.0.. PyTorch + Optuna! Optuna is a hyperparameter optimization framework applicable to machine learning frameworks and black-box optimization solvers. WebWhen using custom learning rate schedulers relying on a different API from Native PyTorch ones, you should override the lr_scheduler_step () with your desired logic. If you are using native PyTorch schedulers, there is no need to override this hook since Lightning will handle it automatically by default.
