Hi all,

I am following the officall site https://developer.leapmotion.com/documentation/python/devguide/Sample_Tutorial.html
to run leapmotion Sample.py and I get the following:

ysu66@mech1331:~$ cd /home/ysu66/LeapSDK/samples
ysu66@mech1331:~/LeapSDK/samples$ python Sample.py
Initialized
Press Enter to quit...

It is not what the site expected, can you tell me why?
