data_reference Module

Represents a reference to data in a datastore.

A DataReference represents a path in a datastore and can be used to describe how and where data should be made available in a run. It is no longer the recommended approach for data access and delivery in Azure Machine Learning. Dataset supports accessing data from Azure Blob storage, Azure Files, Azure Data Lake Storage Gen1, Azure Data Lake Storage Gen2, Azure SQL Database, and Azure Database for PostgreSQL through unified interface with added data management capabilities. It is recommended to use dataset for reading data in your machine learning projects.

• Create and run machine learning pipelines
• Create estimators in training
