Ray

✓ from flytekitplugins.ray import Ray

✗ from flytekitplugins.ray import Ray

Basic Flyte task configured to run on Ray.

from flytekit import task, workflow from flytekitplugins.ray import Ray, RayJobConfig @task(task_config=Ray(job_config=RayJobConfig(worker_groups=[...]))) def my_ray_task() -> str: import ray ray.init() return "Ray task completed" @workflow def wf() -> str: return my_ray_task() if __name__ == "__main__": print(wf())

Debug

Known issues

breakingIn flytekit >=1.12, the Ray plugin API changed: use 'Ray' task_config instead of the old 'RayExecutor'.

fix

Replace 'from flytekitplugins.ray import RayExecutor' with 'from flytekitplugins.ray import Ray' and adjust usage.

affects: >=1.12.0

gotchaRay initialization inside the task may conflict with the Flyte-managed Ray cluster. Avoid calling ray.init() in tasks that use RayJobConfig.

fix

Do not call ray.init() if you are using RayJobConfig; Flyte handles cluster startup automatically.

affects: all

deprecatedThe 'RayJobConfig' worker_groups parameter is being replaced by 'worker_group_spec' in future versions.

fix

Use 'worker_group_spec' instead of 'worker_groups' when available, or check for deprecation warnings.

affects: >=1.16.0
