创建数据存储

适用范围：Azure CLI ml 扩展 v2（最新版）Python SDK azure-ai-ml v2（最新版）

本文介绍如何通过 Azure 机器学习数据存储连接到 Azure 数据存储服务。

先决条件

• Azure 订阅。 如果没有 Azure 订阅，请在开始操作前先创建一个免费帐户。 试用免费版或付费版 Azure 机器学习。

• 适用于 Python 的 Azure 机器学习 SDK。

• Azure 机器学习工作区。

注意

Azure 机器学习数据存储不会创建基础存储帐户资源。 相反，它们链接现有存储帐户以供 Azure 机器学习使用。 这不需要 Azure 机器学习数据存储。 如果有权访问基础数据，可以直接使用存储 URI。

创建 OneLake (Microsoft Fabric) 数据存储（预览版）

本部分介绍了用于创建 OneLake 数据存储的各种选项。 OneLake 数据存储是 Microsoft Fabric 的一部分。 目前，Azure 机器学习支持连接到 Microsoft Fabric Lakehouse 项目，包括文件夹/文件和 Amazon S3 快捷方式。 有关湖屋的详细信息，请访问什么是 Microsoft Fabric 中的湖屋。

OneLake 数据存储创建需要

• 端点
• Fabric 工作区名称或 GUID
• 项目名称或 GUID

来自你的 Microsoft Fabric 实例的信息。 这三个屏幕截图描述了从 Microsoft Fabric 实例检索这些必需的信息资源：

OneLake 工作区名称

在你的 Microsoft Fabric 实例中，你可以找到工作区信息，如以下屏幕截图所示。 你可以使用 GUID 值或“友好名称”来创建 Azure 机器学习 OneLake 数据存储。

OneLake 终结点

以下屏幕截图显示了如何在 Microsoft Fabric 实例中找到终结点信息：

OneLake 项目名称

以下屏幕截图显示了如何在 Microsoft Fabric 实例中找到项目信息。 此屏幕截图还显示了如何使用 GUID 值或“易记名称”来创建 Azure 机器学习 OneLake 数据存储：
