mlOpus 1.4.1

MLOps tools for research and development.

MLOpus

A collection of MLOps tools for AI/ML/DS research and development.

Main features:

• Agnostic experiment tracking and model registry:

  • Compatible with any "MLflow-like" provider through plugins.
  • Search entities in MongoDB Query Language with predicate push-down to the MLflow provider.
  • Local cache for artifacts and entity metadata.
  • Offline mode to work with local cache only.
  • Support for nested tags/params/metrics and JSON-encoded tags/params for non-scalar types.
  • Not dependent on env vars, global vars or a single global active run.

• Artifact Schemas:

  • Packaging framework for models and datasets.
  • Can be used with or without MLflow and/or Kedro.
  • Schemas can be registered by alias at the experiment, run, model or model version.
  • Artifacts catalog for type-safe, configuration-based artifact loading/downloading in serving applications.

• Extended Kedro support:

  • Dynamic pipeline and hook evaluation with direct access to the Kedro config loader.
  • Artifact Schemas can be used in the Kedro datasets catalog.
  • Extend the Kedro CLI with project-specific options, callbacks and param modifiers.
  • Artifacts hook to set up pipeline inputs and/or collect outputs (optionally schema-aware).
  • Highly customizable MLflow tracker hook for storing any pipeline information in experiment runs.

Check the tutorials for a friendly walkthrough of (almost) everything you can do with MLOpus.

Have a look at the architecture guide for an overview of how these and other features work.

A minimal API reference is also available here.
