face_recognition package can't work for me

edit

I followed the guide link text,and input the followed commands

1. Publish /usb_cam/image_raw I'm using shows clearly my face
2. rosrun face_recognition Fserver
3. rosrun face_recognition Fclient
4. rostopic pub -1 /fr_order face_recognition/FRClientGoal -- 2 "your_name"

I got something in the terminal

6. [ INFO] [1489046383.344795519]: Goal just went active

if successful, what result can I expect? I can't find any picture new in the date package?
