No error is reported when it is on the ground and it is in position mode, but why does it start to alert the sensor abnormally and jump into attitude mode when flying together?

@Kevin let's see how we can fix this. First I want to go over what you've done to get the drone ready for flight to rule out everything. Have all the sensors been calibrated?(May need to do that again). Is this flying indoors? If so, the indoor parameters need to be loaded. 
Can you post a pic of the services running? Also what version is flashed?
