Although notebooks are widely used by data scientists for modeling and analysis, many have sharply criticized the practice of using notebooks in production. To enable data scientists to use notebooks safely and reliably for parts of their production workflows (e.g., reporting, visualization, and debugging), Metaflow has released Notebook Cards. With Notebook Cards, users can run notebooks programmatically in Metaflow DAGs. As such, they can isolate notebook-based reporting from business logic, automatically version and organize notebooks, inject custom parameters into notebooks for execution, and more.
