Overview

External tool documentation for building Python distribution packages in the Wandb Weave release process.

Description

The publish_pypi_release.py script's build phase cleans the dist/ directory and runs uv build to produce sdist and wheel files. The build backend is hatchling (configured in pyproject.toml), which reads the version from weave/version.py and includes only the weave/ package.

Usage

Run as part of the publish script, or manually with uv build.
