I follow the Installation for the Naoqi SDKs (http://wiki.ros.org/nao/Tutorials/Installation) and verify my correct Pythonbindings with the command

$ python 
from naoqi import ALProxy

After this Installation I had no errors. The Pythonbindings were correct. Then I follow the Pepper tutorial an try to connect with the robot. After this tutorial, I had errors with the Pythonbindings. I can try the command

from naoqi import ALProxy

and then comes

ImportError: No module named naoqi
