MLOpus

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

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.

Recommended software:

Optional extras:

mlflow: Enables support for the default MLflow plugin, which handles communication with open-source MLflow servers.
search: Enables searching entities with MongoDB query syntax
kedro: Enables Kedro tools (e.g.: hooks, datasets, CLI extensions, etc)

Using pip:

pip install mlopus[mlflow,kedro,search]

Using Poetry:

poetry add mlopus --extras "mlflow,kedro,search"

Using UV:
