sensor.reset() ERROR

I’m working with Maixduino and failing this basic command…

import sensor
sensor.reset()

and it goes…

init i2c2
[MAIXPY]: no sensor
Traceback (most recent call last):
File “”, line 1, in
OSError: Reset Failed

I kept uploading other version of firmware but nothing changed.
How can I fix this problem?
Should I buy a new sensor?
Or could this possibly mean that I installed something wrong…

I’m new in this, please help…
