Grove Python Library - 9DOF ICM20600 AK09918 on Raspberry Pi

Hi, I am trying to get my 9DOF sensor working with my Raspberry Pi via Python. I have tested the sensor on Arduino and it works fine. There are limited examples using the Grove library located here:

From those examples I made this code:

import time
from grove.grove_imu_9dof_icm20600_ak09918 import GroveIMU9DOFICM20600

dofimu = GroveIMU9DOFICM20600()

print('9DOF IMU')
while True:

But I get an error when trying to run:

Any help is much appreciated!
