Thank you for sharing the code.
I have the I2C in i2cdetect -y 1 of the 3 sensors, however, accel and gyro can read data, but compass get failed.
The error message:
Traceback (most recent call last):

By the way, another small problem, for gyro, the expected sampling rate should be 8000Hz. As I modify DLPF_CFG to 0 and modify Sample rate divider to 0 from 7, it should reach 8000 but only 200. It is weird. I modify them in i2c_itg.py in library folder.

Thanks for clarification.
