federicovergallo / sumo-changing-lane-agent Goto Github PK

Sorry, I can't understand the functions of the two lambda and add layers in CarModel

How to solve it?

I have this problem:
please help me, thank u!

When I run to around 1500 rounds, I get an error like this

How to solve this error?

Hello, how are the figures in the report drawn?

Hello
Thank you very much
I run your model after building the env
pip install -e gym_sumo
pip install -r requirements.txt

And I have to change in sumo_env.py

And I had a minor error
