Configuration 专用群集的Apache Ray自动群集设置

我成功地手动设置了一个迷你光线群集（1个头+1个工人，每个人有4个CPU核）。但是，我无法使用ApacheRayAutoScaler自动设置它。头节点正确启动，而工作节点从未加入集群。下面是我对自动缩放器的YAML配置。我做错什么了吗

cluster_name: my_ray_cluster

min_workers: 8
initial_workers: 8
max_workers: 8

provider:
    type: local
    head_ip: 10.148.186.178
    worker_ips: [10.148.186.18]

auth:
    ssh_user: USER_NAME
    ssh_private_key: ~/.ssh/id_rsa

# Files or directories to copy to the head and worker nodes. 
file_mounts: {
#    "/path1/on/remote/machine": "/path1/on/local/machine",
#    "/path2/on/remote/machine": "/path2/on/local/machine",
}

head_setup_commands: 
    - pip3 install ray[debug,dashboard]
setup_commands:
    - pip3 install ray[debug,dashboard]

# Command to start ray on the head node. You don't need to change this.
head_start_ray_commands:
    - ray stop
    - ray start --head --redis-port=6379

worker_start_ray_commands:
    - ray stop
    - ray start --address=10.148.186.178:6379

你能解决它吗？我在私有集群上也面临同样的问题！
