local variable 'logger' referenced before assignment? [closed]

edit

Using fresh install ROS indigo with Ubuntu 14.04 When trying to start openni2_launch I get below error. What could be wrong?

ros@host1:~$ roslaunch openni2_launch openni2.launch
[openni2.launch] is neither a launch file in package [openni2_launch] nor is [openni2_launch] a launch file name
The traceback for the exception was written to the log file
