I am trying to use luigi in the central-scheduler mode. Whenever i try to run the central scheduler by using the command
$ luigid
It returns a syntax error

SyntaxError: invalid syntax
Dont know why, but downgrading tornado does the job.
$ sudo pip install tornado==4.1
$ luigid
Defaulting to basic logging; consider specifying logging_conf_file in luigi.cfg.
