Installation guide

This page discusses how to install and use the code inside the backend.

Install essential python modules

The backend uses the following python modules:

• CARLA
  Follow instructions on CARLA document to install CARLA simulator

• configobj
  Follow instructions on configobj document to install configobj

• Python-control
  Follow instructions on Python-control to install Python-control

• scipy
  Follow instructions on scipy/installation to install scipy

Download and test backend code

• Test the backend only

  Download the GUI Backend and put it in any directory you like as long as the python command import carla works.

  The test file for urban backend is "intersection_backend.py". Open CARLA simulator and run python intersection_backend.py to verify the backend has been successfully installed.

  Note: the first time you run the code, the following error may occur:

  RuntimeError: time-out of 10000ms while waiting for the simulator, make sure the simulator is ready and connected to localhost:2000
  
  UnboundLocalError: local variable 'env' referenced before assignment
  

  This is because the carla client failed to connect to the carla server. Just run the code again and it should be fine.
