but I got the following error

mean while I also run the manual_control.py

Please anyone can help what is the problem.

Hey @nadrainam. Could you please tell me the versions you are using fpr CARLA, ScenarioRunner and py_trees? I can't say for sure but this seems like a missmatch of py_trees version (version 0.8.3 is required).

Hi
The versions are as follows:
Carla 0.911 (as i can see it in the folder :/pyhtonAPI/Carla/Dist)
py_trees version 2.1.4 ( check it with the command pip3 show py-trees| greb Version)
Scenario_runner 0.9.11 ( I check it through command: python3 scenario_runner --help)

I try to install the py-trees version 0.8.3 by using command : pip3 install py-trees=0.8.3
But now when I check the version it is giving me 2.1.4.

I do not know how to install py-trees version 0.8.3

Thank you so much for your reply
