# Using the neptune-export tool or Neptune-Export service to export data from Neptune for Neptune ML
<a name="machine-learning-data-export"></a>

Neptune ML requires that you provide training data for the [Deep Graph Library (DGL)](https://www.dgl.ai/) to create and evaluate models.

You can export data from Neptune using either the [Neptune-Export service](export-service.md), or [`neptune-export` utility](export-utility.md). Both the service and the command line tool publish data to Amazon Simple Storage Service (Amazon S3) in a CSV format, encrypted using Amazon S3 server-side encryption (`SSE-S3`). See [Files exported by Neptune-Export and `neptune-export`](exported-files.md).

In addition, when you configure an export of training data for Neptune ML the export job creates and publishes an encrypted model-training configuration file along with the exported data. By default, this file is named `training-data-configuration.json`.
