Run a python script with supervisor

Question

I copied from here to run my Python code as a daemon. For extra uptime. I thought it would be a better Idea to use supervisor to keep this daemon running.

I did this. python_deamon.conf

[program:python_deamon]
directory=/usr/local/python_deamon/
command=/usr/local/python_venv/bin/python daemon_runnner.py start
stderr_logfile=/var/log/gunicorn.log
stdout_logfile=/var/log/gunicorn.log
autostart=true
autorestart=true

The problem is that though supervisor successfully starts the python_daemon it keeps retrying.

2015-09-23 16:10:53,681 INFO gave up: python_deamon entered FATAL state, too many start retries too quickly

Just for the record the after overriding run() method I never return anything.

Is it possible to do what I am trying to do or am I being dumb ?

P.S: I know that the root cause of the whole problem is that since run() never return anything supervisor keeps trying to start it and hence thinks that the process failed and gives the status as FATAL Exited too quickly (process log may have details).

My actual question is am I doing it right ? or can this be done this way ?

P.P.S: Stand alone(without supervisor) daemon_runnner.py runs fine with and without sudo permissions.

try to set startsecs = 0:

[program:foo]
command = ls
startsecs = 0
autorestart = false
http://supervisord.org/configuration.html

startsecs

The total number of seconds which the program needs to stay running after a startup to consider the start successful. If the program does not stay up for this many seconds after it has started, even if it exits with an “expected” exit code (see exitcodes), the startup will be considered a failure. Set to 0 to indicate that the program needn’t stay running for any particular amount of time.
