早期scikit-learn常见错误是预处理在交叉验证前泄露验证集数据。将特征工程纳入Pipeline，各步骤仅用训练数据拟合，可避免泄露。常用组件有ColumnTransformer、make_column_selector、SimpleImputer、OneHotEncoder和TargetEncoder；set_output与get_feature_names_out便于查看结果，GridSearchCV可一并调优预处理参数。

本文介绍构建和部署自主AI智能体的七个步骤，强调从原型过渡到生产系统需注重编排与部署实践。关键在于预先设定明确边界和护栏，确保智能体在约束内运行。使用LangGraph等框架提供有状态检查点，以构建可靠的多步骤推理循环，实现规模化应用。
