Attributes: redis_address: The address of the Redis server to connect to. If this address is not provided, then this command will start Redis, a raylet, a plasma store, a plasma manager, and some workers. It will also kill these processes when Python exits. redis_port: The port that the primary Redis shard should listen to. If None, then it will fall back to ray._private.ray_constants.DEFAULT_PORT, or a random port if the default is not available. redis_shard_ports: A list of the ports to use for the non-primary Redis shards. If None, then it will fall back to the ports right after redis_port, or random ports if those are not available. num_cpus: Number of CPUs to configure the raylet with. num_gpus: Number of GPUs to configure the raylet with. resources: A dictionary mapping the name of a resource to the quantity of that resource available. labels: The key-value labels of the node. memory: Total available memory for workers requesting memory. object_store_memory: The amount of memory (in bytes) to start the object store with. object_manager_port int: The port to use for the object manager. node_manager_port: The port to use for the node manager. gcs_server_port: The port to use for the GCS server. node_ip_address: The IP address of the node that we are on. min_worker_port: The lowest port number that workers will bind on. If not set or set to 0, random ports will be chosen. max_worker_port: The highest port number that workers will bind on. If set, min_worker_port must also be set. worker_port_list: An explicit list of ports to be used for workers (comma-separated). Overrides min_worker_port and max_worker_port. ray_client_server_port: The port number the ray client server will bind on. If not set, the ray client server will not be started. redirect_output: True if stdout and stderr for non-worker processes should be redirected to files and false otherwise. external_addresses: The address of external Redis server to connect to, in format of "ip1:port1,ip2:port2,...". If this address is provided, then ray won't start Redis instances in the head node but use external Redis server(s) instead. num_redis_shards: The number of Redis shards to start in addition to the primary Redis shard. redis_max_clients: If provided, attempt to configure Redis with this maxclients number. redis_username: Prevents external clients without the username from connecting to Redis if provided. redis_password: Prevents external clients without the password from connecting to Redis if provided. plasma_directory: A directory where the Plasma memory mapped files will be created. object_spilling_directory: The path to spill objects to. The same path will be used as the object store fallback directory as well. worker_path: The path of the source code that will be run by the worker. setup_worker_path: The path of the Python file that will set up the environment for the worker process. huge_pages: Boolean flag indicating whether to start the Object Store with hugetlbfs support. Requires plasma_directory. include_dashboard: Boolean flag indicating whether to start the web UI, which displays the status of the Ray cluster. If this value is None, then the UI will be started if the relevant dependencies are present. dashboard_host: The host to bind the web UI server to. Can either be localhost (127.0.0.1) or 0.0.0.0 (available from all interfaces). By default, this is set to localhost to prevent access from external machines. dashboard_port: The port to bind the dashboard server to. Defaults to 8265. dashboard_agent_listen_port: The port for dashboard agents to listen on for HTTP requests. Defaults to 52365. runtime_env_agent_port: The port at which the runtime env agent listens to for HTTP. Defaults to random available port. plasma_store_socket_name: If provided, it specifies the socket name used by the plasma store. raylet_socket_name: If provided, it specifies the socket path used by the raylet process. temp_dir: If provided, it will specify the root temporary directory for the Ray process. Must be an absolute path. runtime_env_dir_name: If provided, specifies the directory that will be created in the session dir to hold runtime_env files. include_log_monitor: If True, then start a log monitor to monitor the log files for all processes on this node and push their contents to Redis. autoscaling_config: path to autoscaling config file. metrics_agent_port: The port to bind metrics agent. metrics_export_port: The port at which metrics are exposed through a Prometheus endpoint. no_monitor: If True, the ray autoscaler monitor for this cluster will not be started. _system_config: Configuration for overriding RayConfig defaults. Used to set system configuration and for experimental Ray core feature flags. enable_object_reconstruction: Enable plasma reconstruction on failure. ray_debugger_external: If true, make the Ray debugger for a worker available externally to the node it is running on. This will bind on 0.0.0.0 instead of localhost. env_vars: Override environment variables for the raylet. session_name: The current Ray session name. webui: The url of the UI. cluster_id: The cluster ID in hex string. resource_isolation_config: settings for cgroupv2 based isolation of ray system processes (defaults to no isolation if config not provided) """ def __init__( self, redis_address:
