Sylvain Gugger

Former core maintainer of Hugging Face Transformers and co-author of Deep Learning for Coders

Sylvain Gugger's GitHub profile lists past work at Hugging Face and fast.ai. Hugging Face's LLM Course describes Gugger as a Research Engineer at Hugging Face and one of the core maintainers of the Transformers library, and as a former Research Scientist at fast.ai who co-wrote Deep Learning for Coders with fastai and PyTorch with Jeremy Howard. Gugger is a co-author of the paper that introduced the Transformers library and is listed first in the citation for Accelerate, Hugging Face's thin wrapper for running PyTorch training loops on multiple GPUs, TPUs, or mixed precision without boilerplate code.1234

Career

Sylvain Gugger was a Research Scientist at fast.ai before joining Hugging Face as a Research Engineer, where Gugger became one of the core maintainers of the Transformers library. Hugging Face's course page describes Gugger's research focus as making deep learning more accessible through techniques that let models train quickly on limited resources.21

Open-source work

At fast.ai, Gugger co-wrote with Jeremy Howard the 2020 paper describing fastai's layered API, and the two share copyright on the fastbook notebooks, which are used for an online course and form the basis of the book Deep Learning for Coders with fastai and PyTorch.562

Gugger is a co-author of the 2019 paper introducing the Transformers library. In April 2021, Gugger introduced Accelerate on the Hugging Face blog as a library for PyTorch users who want to keep full control of their training loops while running them on several GPUs, TPUs, or in mixed precision.374

Work and contributions

  • Transformers Open-source code

    Co-author of the 2019 paper introducing Hugging Face's Transformers library (arXiv 1910.03771), and described on Hugging Face's LLM Course page as one of the library's core maintainers. The repository is released under the Apache 2.0 license.328

  • Accelerate Open-source code

    Listed first among the authors in the citation entry of the Accelerate README (2022). The Apache-2.0 library lets people who write their own PyTorch training loops run them in distributed or mixed-precision setups.4

  • Deep Learning for Coders with fastai and PyTorch Published research

    Co-wrote the book with Jeremy Howard, according to the author biographies on Hugging Face's LLM Course page; the fastbook repository holds the notebooks the book is based on, copyright Jeremy Howard and Sylvain Gugger from 2020.26

  • fastai: A Layered API for Deep Learning Published research

    Co-author, with Jeremy Howard, of the 2020 paper describing the design of the fastai deep learning library as a set of layered APIs.5
