GÄLLER FÖR:Azure CLI ml extension v2 (current)Python SDK azure-ai-ml v2 (aktuell)

I den här artikeln får du lära dig hur du ansluter till Azure-datalagringstjänster med Azure Mašinsko učenje datalager.

Förutsättningar

• En Azure-prenumeration. Om du inte har någon Azure-prenumeration kan du skapa ett kostnadsfritt konto innan du börjar. Prova den kostnadsfria eller betalda versionen av Azure Mašinsko učenje.
• Azure Mašinsko učenje SDK för Python.
• En Mašinsko učenje arbetsyta.

Kommentar

Mašinsko učenje datalager skapar inte de underliggande lagringskontoresurserna. I stället länkar de ett befintligt lagringskonto för Mašinsko učenje användning. Mašinsko učenje datalager krävs inte. Om du har åtkomst till underliggande data kan du använda lagrings-URI:er direkt.

Skapa ett OneLake-datalager (Microsoft Fabric) (förhandsversion)

I det här avsnittet beskrivs olika alternativ för att skapa ett OneLake-datalager. OneLake-datalagringen är en del av Microsoft Fabric. För närvarande stöder Mašinsko učenje anslutning till Microsoft Fabric Lakehouse-artefakter i mappen "Files" som innehåller mappar eller filer och Amazon S3-genvägar. Mer information om lakehouses finns i Vad är ett sjöhus i Microsoft Fabric?.

Skapande av OneLake-datalager kräver följande information från din Microsoft Fabric-instans:

• Slutpunkt
• Arbetsytans GUID
• Artefakt-GUID

Följande skärmbilder beskriver hämtningen av dessa nödvändiga informationsresurser från din Microsoft Fabric-instans.

Du hittar sedan "Endpoint", "Workspace GUID" och "Artifact GUID" i "URL" och "ABFS path" från sidan Egenskaper:

• URL-format: https://{your_one_lake_endpoint}/{your_one_lake_workspace_guid}/{your_one_lake_artifact_guid}/Files
• ABFS-sökvägsformat: abfss://{your_one_lake_workspace_guid}@{your_one_lake_endpoint}/{your_one_lake_artifact_guid}/Files
