import ray
ray.init()
import asyncio
@ray.remote
class A:
    async def f(self):
        await asyncio.sleep(1)
        ray.actor.exit_actor()

    def ping(self):
        pass

    # async def exit(self):
    #     ray.actor.exit_actor()

a = A.remote()
a.f.remote()
ray.get([a.ping.remote() for _ in range(10000)])

a.exit.remote()
a.other_method.remote()
