The uv package manager has integrated with Ray, a compute engine designed to make it easy to develop and run distributed Python applications, especially AI applications. This integration allows users to manage Python dependencies for distributed applications the same way they normally do on a single machine with uv. The integration uses Ray's runtime environment feature to specify the environment in code and ensures that all worker processes run in the same environment as the driver. This enables consistent worker execution across clusters, significantly improving Python dependency management for distributed systems. The uv integration also supports various features such as editable packages, environment variables, and platform-independent lockfile support. Users can run their Ray jobs with `uv run` to ensure that both the driver and workers run in the uv environment specified by their pyproject.toml file.
