PCA9685报错[Errno 121] Remote I/O error，如何解决？(语言-python)

Question

没错，又是我，我又来提问了[汗]
这次改进之后，处理了一下我的4b的I2C
再次运行之后报错是

File "servo test.py", line 21, in <module>
    pwm = Adafruit_PCA9685.PCA9685()
  File "/usr/local/lib/python3.9/dist-packages/Adafruit_PCA9685/PCA9685.py", line 81, in __init__
    self._device.write8(MODE1, mode1)
  File "/usr/local/lib/python3.9/dist-packages/Adafruit_GPIO/I2C.py", line 114, in write8
    self._bus.write_byte_data(self._address, register, value)
  File "/usr/local/lib/python3.9/dist-packages/Adafruit_PureIO/smbus.py", line 256, in write_byte_data
    self._device.write(data)
IOError: [Errno 121] Remote I/O error

在使用了@Black__Jacket 的方法后依然报错
那么问题到底出在哪里呢？
请各位码友解答
