local variable 'leaderboard_evaluator' referenced before assignment

[dinuransika]

I get the above error when trying to run the run_evaluation.sh. When I wrap the client.get_trafficmanager(int(args.trafficManagerPort)) in a try catch block like this I get the following error.

try:
      self.traffic_manager = self.client.get_trafficmanager(int(args.trafficManagerPort))
  except Exception as e:
      print(e)

Can someone tell me what's wrong there?
