# Python MLOps

Develop machine learning workflows from exploration to evaluated delivery, grounded in the [four reviewed MLOps repositories](references/sources.md).

## Routing

Read only the matching guide. For notebook authoring or reactivity, go directly to marimo; experiment tracking and model delivery are separate tasks. Preserve the project's libraries and notebook format. The reference package illustrates boundaries, not a mandatory architecture.

For ML work, establish permitted compute and artifact destinations before running jobs. Training, tracking, registry writes, and promotion have different effects; inspect the selected task's dependencies before execution.

## Task guides

<!-- guides:start -->

- [experiments](references/experiments.md): Track reproducible MLflow experiments, data lineage, metrics, model signatures, and bounded artifacts.
- [marimo](references/marimo.md): Create, debug, convert, and export reactive marimo Python notebooks and apps, including agent pairing.
- [ml-jobs](references/ml-jobs.md): Turn notebook experiments into typed, configurable ML jobs; select the MLOps template or reference architecture.
- [model-delivery](references/model-delivery.md): Evaluate exact model versions, manage MLflow registry aliases, and verify batch inference and rollback.
- [monitoring](references/monitoring.md): Monitor ML data quality, drift, labeled performance, lineage, and bounded model explanations.
- [polars](references/polars.md): Transform tabular data with Polars lazy queries and expressions; hand frames to Pandera, scikit-learn, and DuckDB.
- [training](references/training.md): Validate Polars or pandas data with Pandera, prevent leakage, and train, tune, and evaluate scikit-learn pipelines.
