Windows using Python(x,y). After the installation I cannot import qutip

    
    
    from qutip import *
    

it gives the error message

    
    
    C:\Python27\lib\site-packages\PIL\Image.py:71: RuntimeWarning: The _imaging extension was built for another version of Pillow or PIL
    

Does anybody know how to fix this?
