I've a problem with the module ueye because it didn't recognize module 
constants, in the following paste i show you the error:  
1.  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "ueye/__init__.py", line 34, in <module>
    from constants import *
         ImportError: No module named constants

and the packeges i downloaded uEye_Linux_350_64Bit,  pyueye-3.50-3.70
