imu示例程序运行报错bno055.py不存在或者无权访问如何解决？

from machine import I2C
from bno055 import BNO055, AXIS_P7
import time
i2c = I2C(2)
imu = BNO055(i2c)
while True:
    #temperature = imu.temperature()
    #print('temperature: ℃',temperature)
    yaw, roll, pitch = imu.euler()
    print('yaw, roll, pitch: °', yaw, roll, pitch)
    #w, x, y, z = imu.quaternion()
    #print('Quaternion:', w, x, y, z)
    #x, y, z = imu.accelerometer()
    #print('Accelerometer (m/s^2):', x, y, z)
    #x, y, z = imu.magnetometer()
    #print('Magnetometer (microteslas):', x, y, z)
    #x, y, z = imu.gyroscope()
    #print('Gyroscope (deg/sec):', x, y, z)
    #x, y, z = imu.linear_acceleration()
    #print('Linear acceleration (m/s^2)', x, y, z)
    #x, y, z = imu.gravity()
    #print('Gravity (m/s^2):', x, y, z)
    time.sleep(100)
