how to take down ray and put up again in local mode about modin

[YarShev]

Hi @SiRumCz, thanks for posting this issue. I guess there might be an issue with multiple Ray initialization in Modin codebase. We would have to look into this deeper. Meanwhile, can you explicitly put ray.init() before run_my_tasks(xxx) to see if it works?

@YarShev Thanks for your response. Yes, I have tried that method, and unfortunately I got:
ValueError: An application is trying to access a Ray object whose owner is unknown(00ffffffffffffffffffffffffffffffffffffff0100000002e1f505). Please make sure that all Ray objects you are trying to access are part of the current Ray session. Note that object IDs generated randomly (ObjectID.from_random()) or out-of-band (ObjectID.from_binary(...)) cannot be passed as a task argument because Ray does not know which task created them. If this was not how your object ID was generated, please file an issue at https://github.com/ray-project/ray/issues/
