Fix RayTaskError
in Ray
✅ Solution
RayTaskError typically arises when an exception occurs during the execution of a Ray task or actor method. Resolve this by implementing robust error handling within your tasks, including try-except blocks and logging, to catch and manage exceptions gracefully, preventing them from propagating and causing RayTaskError. Additionally, ensure task dependencies are correctly defined and data serialization/deserialization is handled appropriately to avoid unexpected failures during task execution.
