YAHP has been deprecated, and removed from Composer in v0.11. We recommend users migrate to OmegaConf or Hydra as alternatives.

YAHP: Yet Another HyperParameter

YAHP introduces yet another hyperparameter management tool.

Features

• Utilizes dataclasses to describe the data model.
• Supports int, float, bool, str, and Enums; along with lists and nullable fields
• Fields can be optional (with a default) or required
• Auto-generates YAML templates, serializes the data model to YAML, and loads YAML into the data model.
• Allows for nested dataclasses -- even with abstract classes
• Adds an argparse CLI

Getting Started

• See the simple example for a simple data model and yaml file.
• See the cli example for an example of the CLI.
• See the registry example for how to use nested dataclasses with inheritance.

YAHP Command Line

Whenever Hparams.create() is invoked, YAHP adds the following command line options:

• -h, --help: Print help and exit.
• -f, --file": Load data from this YAML file into the Hparams.
• -s, --save_template: Generate and dump a YAML template to the specified file (defaults to stdout) and exit.
• -i, --interactive: Whether to generate the template interactively. Only applicable if --save_template is present.
• -c, --concise: Skip adding documentation to the generated YAML. Only applicable if --save_template is present.
