DVC (Data Version Control)

Control de versiones de datos para proyectos de ML. Rastrea grandes conjuntos de datos y modelos junto con Git, construye pipelines de ML reproducibles y ejecuta experimentos con comparación de métricas. Funciona con cualquier backend de almacenamiento, incluyendo S3, GCS, Azure y sistemas de archivos locales.

¿Qué es DVC (Data Version Control)?

Esta skill implementa DVC (Data Version Control) para el control de versiones de datos en proyectos de Machine Learning. Permite rastrear grandes conjuntos de datos y modelos en almacenamiento remoto (S3, GCS, Azure, sistemas de archivos locales) mientras se mantienen pequeños archivos puntero `.dvc` en Git. Facilita la construcción de pipelines reproducibles mediante archivos `dvc.yaml` que definen etapas con dependencias, parámetros, métricas y salidas, ejecutables con un solo comando `dvc repro`. Además, incluye capacidades de experimentación sin ramas (`dvc exp`) para modificar parámetros, ejecutar experimentos en paralelo y comparar resultados, así como acceso programático a datos con la API de Python de DVC. Es compatible con las principales plataformas de almacenamiento en la nube y entornos de desarrollo como Claude Code, Cursor y Codex.
