Problem description

Use supervisor to host the process, and use supervisorctl to report an error:

[~]$ supervisorctl status
error: <class 'OSError'>, [Errno 97] Address family not supported by protocol: file: /home/miniconda3/envs/open3d/lib/python3.7/socket.py line: 151
[~]$ 
[~]$ supervisorctl start all
error: <class 'OSError'>, [Errno 97] Address family not supported by protocol: file: /home/miniconda3/envs/open3d/lib/python3.7/socket.py line: 151
