AttributeError: module 'carla' has no attribute 'WeatherParameters'

Build Carla from source (v 0.9.10) and build scenario runner from source (v 0.9.10) in Windows 10 using python 3.9

Added the environment variables and python paths as shown:
set CARLA_ROOT = C:\Users\simple\Desktop\Carla
set SCENARIO_RUNNER_ROOT = C:\Users\simple\Documents\scenario Runner\scenario_runner
set PYTHONPATH=C:\python;C:\Users\simple\Desktop\Carla\PythonAPI\carla\dist\carla-0.9.10-py3.9-win-amd64
set PYTHONPATH=C:\python;C:\Users\simple\Desktop\Carla\PythonAPI\carla
set PYTHONPATH=C:\python;C:\Users\simple\Desktop\Carla\PythonAPI

Note: In C:\Users\simple\Desktop\Carla\PythonAPI\carla\dist\ .egg filename was ‘carla-0.9.10-py3.9-win-amd64’ without .egg . So while setting the python path, set the path as:
set PYTHONPATH=C:\python;C:\Users\simple\Desktop\Carla\PythonAPI\carla\dist\carla-0.9.10-py3.9-win-amd64

Then tried the following:

In a new terminal,
Ran the carla server from carla root directory using the command: make launch
Pressed Play in the UE editor.

In another terminal,
executed: python --scenario FollowLeadingVehicle_1 --reloadWorld
and got the below error:

C:\Users\simple\Documents\scenario Runner\scenario_runner>python --scenario FollowLeadingVehicle_1 --reloadWorld

AttributeError: module ‘carla’ has no attribute ‘WeatherParameters’

Desktop :

  • OS: [Windows 10]
  • CARLA Version [CARLA 0.9.10]
  • Python version [3.9.0] [Only python 3.9 is installed in system]
  • Scenario_runner Version [0.9.10]

Please provide support for this issue. Is scenario_runner compatible with python 3.5 and 3.6 only and not with 3.9?
