GitHub - optuna/optuna: A hyperparameter optimization framework

Optuna is an automatic hyperparameter optimization software framework, particularly designed for machine learning. It features an imperative, define-by-run style user API. Thanks to our define-by-run API, the code written with Optuna enjoys high modularity, and the user of Optuna can dynamically construct the search spaces for the hyperparameters. Early adopters may want to upgrade and provide feedback for a smoother transition to the coming full release. You can install a pre-release version by pip install -U --pre optuna.
