The raspberry has two I²C busses.

bus 0: pins 27, 28 bus 1: pins 3,5 (default)

If you connected the mpu6050 to 27 and 28 you will have to specify bus=0:

from mpu6050 import mpu6050
sensor = mpu6050(0x68, bus=0)
accelerometer_data = sensor.get_accel_data()

If you’re using the wrong bus you’ll also get the OP’s error.

For more info about the pins see: https://pinout.xyz/pinout/i2c

Alright so the answer was super simple. It was cheap and faulty due to my soldering. Since it’s pretty cheap I just bought a new set and soldered it worked perfectly fine.

Lesson of the story is, there might be a slight chance you just have a fault accelerometer. It’s cheap for a reason.
