Azure CLI ml 扩展 v2（当前版本）Python SDK azure-ai-ml v2（当前版本）
本文介绍如何使用 Azure Machine Learning 的数据存储来连接到 Azure 数据存储服务。
先决条件
小窍门
本文中的 Python SDK 代码示例使用 MLClient.from_config()，这需要在当前目录或父目录中有一个 config.json 文件。 从 Azure 门户下载此文件：转到工作区，然后选择 “概述>下载”config.json。 或者，可以手动创建 MLClient ：
ml_client = MLClient(
credential=DefaultAzureCredential(),
subscription_id="<your-subscription-id>",
resource_group_name="<your-resource-group>",
workspace_name="<your-workspace-name>",
)
注意事项
机器学习数据存储不会创建基础存储帐户资源。 相反，它们链接了用于机器学习使用的现有存储帐户。
每个数据存储类型都是独立创建的。 本文中各节的顺序并不表示所需的步骤序列。
创建Azure Blob 数据存储
from azure.ai.ml.entities import AzureBlobDatastore
from azure.ai.ml import MLClient
from azure.identity import DefaultAzureCredential
ml_client = MLClient.from_config(credential=DefaultAzureCredential())
store = AzureBlobDatastore(
name="",
description="",
account_name="",
container_name=""
)
ml_client.create_or_update(store)
from azure.ai.ml.entities import AzureBlobDatastore
from azure.ai.ml.entities import AccountKeyConfiguration
