Hello,
I found this interesting project recently. I am now wondering if it is possible to use commonroad-geo for rl training. Any example? or any example of using commonroad-geo with simulators like CARLA or other simulators?
Thank you.
Hi,
The graph representations are still not integrated in CommonRoad-RL as of now. However, there is a gym environment included in the CommonRoad-Geometric package that you can use. It also includes an interface to SUMO for traffic simulation.

Thank you @eivmeyer for the answer.
I see more projects are adding in the repo for commonroad-geometric for rl.
Is there any readme that I can read more about those? Like highway_lane_rep, lane_occupancy, or trajectory_prediction projects.
Hi,
At the moment not for all, unfortunately. They are work in progress can serve as implementation examples. The lane_occupancy project is presented here: https://arxiv.org/pdf/2303.04218

Thank you for the answer 
And other projects are not related to any published paper, right?
I’m now trying to run the project.
When I try to run python projects/graph_rl_agents/lane_occupancy/run.py, I get the error when it wants to load the model I think. However I see the model projects/graph_rl_agents/lane_occupancy/occ_encoder_model_pretrained_munich.pt. Here is the error
ModuleNotFoundError: No module named 'tutorials.train_geometric_model'
Then I try to run the geometric_model using python projects/geometric_models/lane_occupancy/run.py cmd=train to train the model again, I assume. But it again seems to need data:
raise CommonRoadDatasetMissingException(f"Raw dataset in {self.raw_dir} is missing or directory is empty.")
commonroad_geometric.dataset.commonroad_dataset.CommonRoadDatasetMissingException: Raw dataset in crgeo/data/munich3_valid2 is missing or directory is empty.
It’s two to three weeks that I’m just trying to run the code. Is there any clear instruction on what is needed and what is needed to run it? The documentation is incomplete.
