Is this Windows?  Is it a GUI application?  If so, I found that when 
deployed my sys.stdout and sys.stderr were actually None.  I won't 
recommend what I have done as _good_ but I will share it in case it is 
_useful_ at least for exploration.


Roughly speaking I replace sys.stdout and sys.stderr *shudder* with 
either my log file or my tee object which sends to both the file and 
stdout/err.  Nasty, but without it I was flying totally blind except 
that my application stopped running.  Someday I'll do a proper logging

My understanding is that that is for Python 2 for parsing the code file 
itself and would not be relevant here.
