ImportError: cannot import name 'encode_traffic_light_state' from 'utilities.networks'

[Wu-didi]

Description:
When I try to run the command python3 run/main.py -en rlad_original, I encounter the following error:

File "/root/rlad/carla_env/core/task_actor/ego_vehicle/reward/valeo_action_updated.py", line 11, in <module>
    from utilities.networks import encode_traffic_light_state
ImportError: cannot import name 'encode_traffic_light_state' from 'utilities.networks' (/root/rlad/utilities/networks.py)

It seems that the function encode_traffic_light_state is missing from utilities/networks.py.

Steps to Reproduce:

1. Clone the repository.
2. Follow the installation steps.
3. Run the command: python3 run/main.py -en rlad_original.

Expected Behavior:
The program should execute without throwing an ImportError.

Actual Behavior:
The program raises an ImportError stating that the function encode_traffic_light_state is not found in utilities/networks.py.

Possible Solutions:

• If encode_traffic_light_state was intended to be part of the utilities/networks.py module, it might be missing from the current version. Can you provide the correct implementation of this function?
• If it has been deprecated or replaced, could you guide me on the correct method to handle traffic light state encoding?
