sklearn 兼容

MPSBoost estimator 遵循 sklearn 风格接口：

• fit
• predict
• predict_proba
• decision_function
• score
• get_params
• set_params

Model selection

from sklearn.model_selection import GridSearchCV
import mpsboost as mb

search = GridSearchCV(
    mb.GradientBoostingClassifier(device="auto"),
    param_grid={"max_depth": [2, 3], "n_estimators": [20, 50]},
    cv=3,
)
search.fit(X_train, y_train)

导入期 MPS 环境检查不会使用交互输入。CPU-only worker 可以通过以下命令跳过环境检查：

MPSBOOST_SKIP_ENV_CHECK=1 python your_script.py
