Mode must not be a fusion mode

[jalzone]

I keep getting this error when running on a Raspberry Pi with python3.

Traceback (most recent call last): File "/home/pi/9dof.py", line 39, in <module> sensor = adafruit_bno055.BNO055_I2C(i2c, 0x28) File "/usr/local/lib/python3.9/dist-packages/adafruit_bno055.py", line 793, in __init__ super().__init__() File "/usr/local/lib/python3.9/dist-packages/adafruit_bno055.py", line 232, in __init__ self.gyro_range = GYRO_2000_DPS File "/usr/local/lib/python3.9/dist-packages/adafruit_bno055.py", line 576, in gyro_range raise RuntimeError("Mode must not be a fusion mode") RuntimeError: Mode must not be a fusion mode

Besides
import adafruit_bno055
Line 39 is the first line of the script concerning the library. Sensor mode is set after this line as either IMUPLUS or NDOF, but even when there is no mode set after, the error persists. Strangest thing is that it will work and run through the script on rare occasions, where it will run through a calibration routine and then data collection.
