mpu6050 error getting the proper raw data values

When I run the code, I always get -1 as output for all the 6 outputs of gyroscope and accelerometer.I am uploading the output as seen in serial monitor also.

Thankyou

Which Arduino are you using? You may need an I2C level shifter for connecting the 3.3V MPU to an 5V Arduino. Show your circuit diagram?
