This commit fix this issue

[tongtybj]

sorry, I pasted the wrong error log. The path had been fixed by myself in local pc.
The true error log belonging to the face_recognition is as follows:

okay....

1. please do not edit files with sudo. you can use sudo only for apt command. if someone told you to change the code or run command by sudo emacs or sudo vi, that's is a very bad person.
2. if you ask someone, please provide how to reproduce your problem in other's computer. for example, you can run test-face_recognition.test with bag file http://download.ros.org/data/face_detector/face_detector_withface_test_diamondback.bag or you can provide your bag file
3. please add expected behavior and why you think you have a problem

[k-okada]

please check contents of ~/.ros/opencv_apps/face_data/, is there is no image file, you need to take pictures of your face from face_recognition_trainer.py window

[tongtybj]

@k-okada

Thank you for the important advice and instruction.
I was the bad guy being reformed, and have checked the expected behaviour by test-face_recognition.test.

Right now I know the the pasted error log is from here, caused because of no trained data.
So it always occurs in the taking pictures phase.

Finally, the expected result is also confirmed with my face.

Suggestion:
Maybe, it is better to add a line here, to check the size of the label_mapper_. If it is empty, then just return from this callback, avoiding the confusion.
