Next steps
  To add another node to this Ray cluster, run
    ray start --address='192.168.71.129:6379'

  To connect to this Ray cluster:
    import ray
    ray.init(_node_ip_address='192.168.71.129')

  To submit a Ray job using the Ray Jobs CLI:
    RAY_API_SERVER_ADDRESS='http://127.0.0.1:8265' ray job submit --working-dir . -- python my_script.py

  See https://docs.ray.io/en/latest/cluster/running-applications/job-submission/index.html
  for more information on submitting Ray jobs to the Ray cluster.

  To terminate the Ray runtime, run
    ray stop

  To view the status of the cluster, use
    ray status

  To monitor and debug Ray, view the dashboard at
    127.0.0.1:8265

  If connection to the dashboard fails, check your firewall settings and network configuration.

value=1
Stopped only 6 out of 7 Ray processes within the grace period 16 seconds. Set `-v` to see more details. Remaining processes [psutil.Process(pid=12595, name='python3', status='terminated')] will be forcefully terminated.
You can also use `--force` to forcefully terminate processes or set higher `--grace-period` to wait longer time for proper termination.

【重要提示】

必须要把libtest_lib.so库编译出来，否则无法运行test程序，报ray::internal::RayFunctionNotFound: Executable function not found的错误。
