Update hyperparameter optimization code for Optuna v3.0.0
Motivation
Optuna v3.0.0 was released in 29 August 2022, and Trial.suggest_uniform
was deprecated. Please use Trial.suggest_float
as described in the migration guide.
Changes
This PR simply replace Trial.suggest_uniform
with Trial.suggest_float
. This does not change the behavior since Trial.suggest_uniform
is now just an alias of Trial.suggest_float
as can be seen in this source code.
