optuna.distributions
The ~optuna.distributions module defines various classes representing probability distributions, mainly used to suggest initial hyperparameter values for an optimization trial. Distribution classes inherit from a library-internal ~optuna.distributions.BaseDistribution, and is initialized with specific parameters, such as the low and high endpoints for a ~optuna.distributions.UniformDistribution.
Optuna users should not use distribution classes directly, but instead use utility functions provided by ~optuna.trial.Trial such as ~optuna.trial.Trial.suggest_int.
