run_mpc.py: quadcopter just flew away

[t-thanh]

Hi,

I just clone the repository and test with python run_mpc.py after deleting some comments to record the animation. However the drone seems to be out of control - just fly away from the pendulum - see the attached video

Is that something missing from the set-up?

Best regards,

Hi,

I have never encountered such a problem before. Are you able to run the code (without deleting anything) when you clone the code.

Hi @yun-long ,

Yes, I'm able to run the code like it is from the repository.
output of python run_mpc.py is:

Fix by downgrade the matplotlib from 3.3.3 (python3.8) to 3.1.1
