I've installed RPIO library to my RPI following these instructions: $ sudo apt-get install python-setuptools $ sudo easy_install -U RPIO I'm trying to run this code (test.py): from RPIO import PWM servo = PWM.Servo() servo.set_servo(7,1000) servo.stop_servo(7) using `sudo python test.py` it works, but using `sudo python3 test.py` it displays: `ImportError: No module named RPIO` In the [Documentation][1] is written that we can use the library both in Python 2 and 3. Any idea? [1]: http://pythonhosted.org/RPIO/
