Zeppelin File-Based Access

Zeppelin notebooks offer a web-based interactive development environment for coding and accessing data. They're generally used to support a wide range of workflows in data science, scientific computing, and machine learning. The integration of Ascend and a Zeppelin notebook creates a direct link to live data, without having to first go through any intermediate storage. Ascend's File-Based Access powers this integration.

Prerequisites

• A Python development environment with Zeppelin Notebooks installed
• An Ascend Access Key ID and Secret, either through a Service Account or a Developer Access Key.
