Migration overview

Use Neptune Exporter to export your data from Neptune and optionally load it into other experiment tracking tools.

Migration steps:

1. Check your Neptune version and choose the corresponding export guide.
2. Use the Neptune Exporter CLI to get your data from Neptune.
3. (Optional) Load the data into another tool.

Neptune Exporter

Neptune Exporter is a command-line tool for downloading your data from Neptune and migrating it into other platforms. It supports the following actions:

• Download runs from Neptune to your local storage as Parquet files.
• Load the Parquet files into MLflow or Weights & Biases. The run structure, that includes forks, steps, and attributes, is preserved as closely as possible.
• Validate your exports with a human-readable summary of the data layout.

You can use Neptune Exporter with both Neptune 2.x and Neptune 3.x.

The README file contains detailed prerequisites and complete usage instructions.

  • If you usually read docs at docs.neptune.ai, you're on Neptune 3.x.
  • If you usually read docs at docs-legacy.neptune.ai (legacy docs), you're on Neptune 2.x.

• Python packages/imports:

  • If you use neptune-scale and/or neptune-query (from neptune_scale import ...), you're on 3.x.
  • If you use the neptune package (import neptune), you're likely on 2.x.
