Fix ObjectLostError

in Ray

Solution

ObjectLostError usually means a Ray worker node holding an object died, causing the object to be lost from the object store. To fix this, ensure sufficient resources and stability in your Ray cluster to prevent worker node failures. Implement object spilling to disk or object replication across multiple nodes for fault tolerance to persist data even if a worker fails.
