requirements: update optuna requirement from <4.2.0 to <4.3.0

[dependabot]

Updates the requirements on optuna to permit the latest version.

Release notes

Sourced from optuna's releases.

v4.2.0

This is the release note of v4.2.0. In conjunction with the Optuna release, OptunaHub 0.2.0 is released. Please refer to the release note of OptunaHub 0.2.0 for more details.

Highlights of this release include:

• 🚀gRPC Storage Proxy for Scalable Hyperparameter Optimization
• 🤖 SMAC3: Support for New State-of-the-art Optimization Algorithm by AutoML.org (@​automl)
• 📁 OptunaHub Now Supports Benchmark Functions
• 🧑‍💻 Gaussian Process-Based Bayesian Optimization with Inequality Constraints
• 🧑‍💻 c-TPE: Support Constrained TPESampler

Highlights

gRPC Storage Proxy for Scalable Hyperparameter Optimization

The gRPC storage proxy is a feature designed to support large-scale distributed optimization. As shown in the diagram below, gRPC storage proxy sits between the optimization workers and the database server, proxying the calls of Optuna’s storage APIs.

In large-scale distributed optimization settings where hundreds to thousands of workers are operating, placing a gRPC storage proxy for every few tens can significantly reduce the load on the RDB server which would otherwise be a single point of failure. The gRPC storage proxy enables sharing the cache about Optuna studies and trials, which can further mitigate load. Please refer to the official documentation for further details on how to utilize gRPC storage proxy.

SMAC3: Random Forest-Based Bayesian Optimization Developed by AutoML.org

SMAC3 is a hyperparameter optimization framework developed by AutoML.org, one of the most influential AutoML research groups. The Optuna-compatible SMAC3 sampler is now available thanks to the contribution to OptunaHub by Difan Deng (@​dengdifan), one of the core members of AutoML.org. We can now use the method widely used in AutoML research and real-world applications from Optuna.

# pip install optunahub smac
import optuna
import optunahub
from optuna.distributions import FloatDistribution
def objective(trial: optuna.Trial) -> float:
x = trial.suggest_float("x", -10, 10)
y = trial.suggest_float("y", -10, 10)
return x2 + y2
smac_mod = optunahub.load_module("samplers/smac_sampler")
n_trials = 100
sampler = smac_mod.SMACSampler(
{"x": FloatDistribution(-10, 10), "y": FloatDistribution(-10, 10)},
n_trials=n_trials,
)
study = optuna.create_study(sampler=sampler)
study.optimize(objective, n_trials=n_trials)

Please refer to https://hub.optuna.org/samplers/smac_sampler/ for more details.
