Issue When Running run_model.py (Key Error)

[techGIAN]

I have already installed the necessary requirements and now about to try to run run_model.py (with map matching task, STMatching model and T_DRIVE_SMALL dataset, and the rest remains default) however I am getting a key error. I am not sure how I can resolve the error? Thank you so much.

STMatching is a road network matching model for mapping GPS trajectories to corresponding road segments. But T-Drive-Small is a gridded traffic flow dataset, not the original Beijing trajectory data, so this is a mismatch, so it will report an error.
The matching relationship between the model and the data can be found in this link.
If you need to match the original T-Drive trajectory data to the road network, you can process T-Drive into a trajectory atomic file, and then you can use the code in LibCity.
