Welcome to OptunaHub’s documentation!
OptunaHub is a registry of third-party packages designed for Optuna. It allows users to share and discover Optuna packages that are not included in the official Optuna distribution. The optunahub library provides Python APIs to load and use packages from the OptunaHub registry.
Usage
Install the optunahub package.
pip install optunahub
Load the package you want from the OptunaHub registry. In the next example code, you will load the SimulatedAnnealingSampler from the samplers/simulated_annealing package.
import optuna
import optunahub
def objective(trial: optuna.Trial) -> float:
x = trial.suggest_float("x", 0, 1)
return x
mod = optunahub.load_module("samplers/simulated_annealing")
study = optuna.create_study(sampler=mod.SimulatedAnnealingSampler())
study.optimize(objective, n_trials=20)
print(study.best_trial.value, study.best_trial.params)
Now that you’ve successfully loaded a package from the OptunaHub registry, you can start using optunahub in your optimization! Get ready to explore the most suitable packages for your problems in the OptunaHub registry.
