Help！Raspberry PI3 conected to BNO080 are having problems.

[WSC0815]

An unknown error occurred when using the raspberry PI to connect to the BNO080 sensor via i2C.

I completely follow the tutorial configuration and run the example, but there are the following problems, I don't know how to do, I hope someone can help me, thank you very much!

This is the code I used.（It is the same as the test code in the library.）
code：

import board
import busio

from adafruit_bno08x.i2c import BNO08X_I2C
from adafruit_bno08x import BNO_REPORT_ACCELEROMETER

i2c = busio.I2C(board.SCL, board.SDA)
bno = BNO08X_I2C(i2c)
bno.enable_feature(BNO_REPORT_ACCELEROMETER)

while True:
accel_x, accel_y, accel_z = bno.acceleration # pylint:disable=no-member
print("X: %0.6f Y: %0.6f Z: %0.6f m/s^2" % (accel_x, accel_y, accel_z))

Can you repost the screen cap of the issue, or the text of the error message. The first post attachment didn't come through for some reason.

Looks like known clock stretching issue.
