Hydra Ecosystem

Check out these third-party libraries that build on Hydra's functionality:

  • hydra-zen: Pythonic utilities for working with Hydra. Dynamic config generation capabilities, enhanced config store features, a Python API for launching Hydra jobs, and more.
  • lightning-hydra-template: user-friendly template combining Hydra with Pytorch-Lightning for ML experimentation.
  • hydra-torch: configen-generated configuration classes enabling type-safe PyTorch configuration for Hydra apps.
  • NVIDIA's DeepLearningExamples repository contains a Hydra Launcher plugin, the distributed_launcher, which makes use of the pytorch distributed.launch API.
