Ludwig

Ludwig: Declarative Deep Learning Framework Overview

Ludwig is an open-source declarative deep learning framework built on PyTorch. It streamlines the machine learning workflow by allowing users to define their entire ML pipeline, including data preprocessing, model architecture, and training configurations, using a simple YAML file. This declarative approach significantly reduces the need for writing extensive boilerplate code, enabling users to focus on model development rather than infrastructure.

The framework supports a wide range of data modalities, including tabular data, text, images, and audio, making it a versatile tool for various AI tasks. Its seamless integration with distributed computing frameworks like Ray allows for effortless scaling from a local machine to large clusters without code modifications. Ludwig also offers comprehensive support for LLM fine-tuning, incorporating advanced techniques like LoRA, QLoRA, and various alignment methods. Its production-ready features include model serving capabilities and export options for various formats, making it suitable for both research and deployment scenarios.
