Ray can't be initialized while connected to redis

System information
OS: Windows 10
Ray: 1.2.0
Python: 3.7 64-bit

Problem description:
Running the script on a github program about DML and I built a simple redis cluster with 3 nodes and 3 slaves on my local laptop, but ray can’t be initialized when it tries to connect to the redis cluster. I am pretty sure that I open the redis cluster mode.
Console/debugger outputs look like this:

Hi @Vow_LIU is there a reason you’re trying to manually start redis instead of letting Ray do it for you? You can pass --redis-shard-ports to ray start to start a sharded instance of redis.
