MPU6050&ADXL345 chip not found error

The gyroscopic sensor MPU6050 chip not found is popping up every time I run my code. The problem is probably not with my code rather with the library code. I think the address of MPU6050 changes every time I flash the chip. Is there any way to solve these problems? I'm using GY-291 which has MPU6050 on it. MPU 6050 datasheet:https://invensense.tdk.com/wp-content/uploads/2015/02/MPU-6000-Datasheet1.pdf

No, the address is fixed.

After reading the "How to get the best out of this forum" post, please follow the instructions and post the code (using code tags), wiring diagram, etc.

To check I2C communications and wiring, run the Arduino I2C Address Scanner program.

Even the I2C scanner couldn't find any I2C device in my case although the wirings were correct
