[Serve] Ray Serve, RayActorError: The actor died unexpectedly before finishing this task

Ray version 0.8.4, trying to follow this blog:

from ray import serve

ray.init(address='auto', ignore_reinit_error=True)

RayActorError: The actor died unexpectedly before finishing this task.

Unsure how to fix this. Is this a version error?

Hi @Carterbouley , you’re on a really old version of ray. Today, I expect, ray 1.3 will be released, and you should go back and check out the instructions for that. In particular what you’ll find is that serve.start(detached=True) is used to fire up a serve instance that doesn’t die when the wrapping script finishes.
