When running python3 demo.py, it gives me error:

Thanks for your comment. Incorrect format of cfg/simulator.cfg could raise this error. If your operating system is Windows and you have set git config --global core.autocrlf true , when you clone this repo, git will automatically add CR to cfg/simulator.cfg. This will lead to your error in Linux of the docker container. So please change cfg/simulator.cfg from CRLF to LF after cloning this repo.
