Machine Learning Model and Dataset Versioning

Kurian Benoy (~kurianbenoy)


In this talk we will discuss about the current practices of organizing ML projects using traditional open-source tool set like Git and Git-LFS as well as this tool set limitation. Thereby motivation for developing new ML specific version control systems will be explained.

Currently the life-cycle of any Machine learning model goes through following process:

  • a ML practitioner tries out new image classification algorithm with input dataset
  • He tweaks algorithms, tries other ideas and fix bugs. All in local system
  • Some of her training data might require long runs, and may change code while weights remains same
  • She keeps around the model weights and evaluation scores for all her runs, and picks which weights to release as the final model once she’s out of time to run more experiments.
  • She publishes her results, with code and the trained weights.

Git can’t handle large amount of data of GB’s of size. While Git-LFS comes with the in-build difficulty of supporting only 2 GBs of data at the maximum.(github limitations)

Data Version Control or DVC.ORG is an open source, command-line tool written in Python. We will show how to version datasets with dozens of gigabytes of data and version ML models, how to use your favorite cloud storage (S3, GCS, or bare metal SSH server) as a data file backend and how to embrace the best engineering practices in your ML projects.
