Ray v0.7.6 Release Notes

Release Date: 2019-10-24 // over 4 years ago

  • 🚀 Ray 0.7.6 Release Notes

    Highlights

    👍 The Ray autoscaler now supports Kubernetes as a backend (#5492). This makes it possible to start a Ray cluster on top of your existing Kubernetes cluster with a simple shell command.

    - This is a new feature and may be rough around the edges. If you run into problems or have suggestions for how to improve Ray on Kubernetes, please file an issue.

    🔊 The Ray cluster dashboard has been revamped (#5730, #5857) to improve the UI and include logs and error messages. More improvements will be coming in the near future.

    • You can try out the dashboard by starting Ray with ray.init(include_webui=True) or ray start --include-webui.
    • Please let us know if you have suggestions for what would be most useful to you in the new dashboard.
