本页面介绍了如何创建和管理 AML AI 模型。 创建模型以启动 AML AI 的机器学习训练流水线。您可以使用模型在各种数据集上运行预测或回测。
此时,您只需创建模型并导出关联的元数据。其他模型方法只是为了完整起见而提供的。
准备工作
-
为了获得创建和管理引擎模型所需的权限, 请让管理员授予您 Financial Services Admin (
financialservices.admin
) 项目的 IAM 角色。 如需详细了解如何授予角色,请参阅管理对项目、文件夹和组织的访问权限。 - 创建实例
- 创建引擎配置
- 创建数据集
创建模型
有些 API 方法会返回 长时间运行的操作 (LRO)。 这些方法是异步的,并返回 Operation 对象;有关详情,请参阅 REST 参考文档。当方法返回响应时,操作可能尚未完成。对于这些方法,请将 然后查看结果一般来说,所有 POST、PUT、UPDATE 和 DELETE 操作 长期运行
