@ray.remote
class Actor:
    def get_task_id(self):
        return ray.get_runtime_context().get_task_id()

@ray.remote
def get_task_id():
    return ray.get_runtime_context().get_task_id()

# All the below code generates different task ids.
a = Actor.remote()
# Task ids are available for actor tasks.
print(ray.get(a.get_task_id.remote()))
# Task ids are available for normal tasks.
print(ray.get(get_task_id.remote()))
