Library is not compatible with Python 3

These errors occur:

Traceback (most recent call last):
  File "example.py", line 4, in <module>
    from ina219 import INA219
  File "/home/pi/pi_ina219/ina219.py", line 7, in <module>
    import Adafruit_GPIO.I2C as I2C
ImportError: No module named 'Adafruit_GPIO'

and:

  File "example.py", line 14
    print "Bus Voltage    : %.3f V" % ina.voltage()

On a new installation of Raspbian I did:

1. Enabled I2C in raspi-config
2. Create a python test file containing just the two imports at the top of your file
3. Ran my test file with python3 -> gave the same import error you get
4. Installed Adafruit_GPIO with: pip3 install AdaFruit_GPIO
5. Ran my test file again -> succeeded with no errors

So from this is does look like your system is to blame. So reinstalling Rasbian will work.

To install dependencies for Python 3 on Raspberry Pi, this need to be executed: sudo python3 -m pip install git+git://github.com/chrisb2/pi_ina219.git this fixes the import error above.
