hydra-zen is a Python library that simplifies the process of writing code (research-grade or production-grade) that is:
- Configurable: you can configure all aspects of your code from a single interface (the command line or a single Python function).
- Repeatable: each run of your code will be self-documenting; the full configuration of your software is saved alongside your results.
- Scalable: launch multiple runs of your software, be it on your local machine or across multiple nodes on a cluster.
hydra-zen eliminates all hand-written yaml configs from your Hydra project. It does so by providing functions that dynamically and automatically generate dataclass-based configs for your code. It also provides a custom config-store API and task-function wrapper, which help to eliminate most of the Hydra-specific boilerplate from your project.
