I've built the carla server (from release), unrealengine and carla client (from dockerfile in this repo)
And I started with
bash CarlaUE4.sh -carla-setteings=./Example.CarlaSettings.ini
The CarlaUE4 started successfully.
then I trieddocker run -it -d -p 2000-2002:2000-2002 avfi_carla to run the image built by this dockerfile.

and python3 run_CIL.py to run AVFI.

I keep getting this

INFO: START
