Machine Learning Engineering Open Book

This is an open collection of methodologies, tools and step by step instructions to help with successful training of large language models and multi-modal models.

This is a technical material suitable for LLM/VLM training engineers and operators. That is the content here contains lots of scripts and copy-n-paste commands to enable you to quickly address your needs.

This repo is an ongoing brain dump of my experiences training Large Language Models (LLM) (and VLMs); a lot of the know-how I acquired while training the open-source BLOOM-176B model in 2022 and IDEFICS-80B multi-modal model in 2023. Currently, I'm working on developing/training open-source Retrieval Augmented Generation (RAG) models at Contextual.AI.

I've been compiling this information mostly for myself so that I could quickly find solutions I have already researched in the past and which have worked, but as usual I'm happy to share these with the wider ML community.

Table of Contents

My apologies if the layout is a bit unstable while I'm writing new chapters and gradually re-organizing the content to be more intuitive.

  1. The AI Battlefield Engineering - what you need to know in order to succeed

Part 2. Hardware

  1. Compute - accelerators, CPUs, CPU memory.

  2. Storage - local, distributed and shared file systems.

  3. Network - intra- and inter-node networking.

Part 3. Orchestration

  1. SLURM - the main orchestration environment

Part 4. Training

  1. Training - model training related guides

Part 5. Development

  1. Debugging and Troubleshooting - how to debug easy and difficult issues

  2. And more debugging

  3. Testing - numerous tips and tools to make test writing enjoyable

Part 6. Miscellaneous

  1. Resources - LLM/VLM chronicles

Download the PDF version of the book.

I will try to rebuild it once a week or so, but if you want the latest, the instructions for building are here.

Thanks to HuggingFace for giving me permission to host my book's PDF at the HF hub.

Gratitude

None of this would have been possible without me being entrusted with doing the specific LLM/VLM trainings I have learned the initial know-how from. This is a privilege that only a few enjoy due to the prohibitively expensive cost of renting huge ML compute clusters. So hopefully the rest of the ML community will vicariously learn from these notes.

Special thanks go to Thom Wolf who proposed that I lead the BLOOM-176B training back when I didn't know anything about large scale training. This was the project that catapulted me into the intense learning process. And, of course, HuggingFace for giving me the opportunity to work full time on BLOOM-176B and later on IDEFICS-80B trainings.

Currently, I'm continue expanding my knowledge and experience while training models and building systems at Contextual.AI and I'm grateful to that opportunity.

I'd also like to say thanks to the numerous contributors who have been making this text awesome and error-free.
