Uv and Ray: Pain-Free Python Dependencies in Clusters
Pain-free Python dependencies in clusters with uv + Ray! Learn how to build lightning-fast, consistent environments for distributed applications.
Designed with speed in mind, uv quickly downloads packages, caches them locally on disk, de-duplicates dependencies between environments and uses hard links to bring them all together. The traditional way to solve this problem is by containerizing everything, but that makes the development iteration much slower - if code and dependencies change, a new version of the container needs to be built and pushed to all nodes. Use uv lock to generate a lockfile and make sure all your dependencies are frozen, so things won’t change in uncontrolled ways if a new version of a package gets released.
