FileNotFoundError: [Errno 2] No such file or directory: './cfg/episode_routes.rou.xml'

[TrinhTuanHung2021]

Thank you for sharing your coding. When I ran python train.py -c config.yaml, it gave error FileNotFoundError: [Errno 2] No such file or directory: './cfg/episode_routes.rou.xml'

I checked that folder and I did not see episode_routes.rou.xml file.

Could you show me how to create this file or you can upload it to github for user convenience. Thank you

I tried to create the episode_routes.rou.xml file with the coding in generator.py as below

    <vType accel="1.0" decel="4.5" id="standard_car" length="5.0" minGap="2.5" maxSpeed="25" sigma="0.5" />
    <route id="W_N" edges="W2TL TL2N"/>
    <route id="W_E" edges="W2TL TL2E"/>
    <route id="W_S" edges="W2TL TL2S"/>
    <route id="N_W" edges="N2TL TL2W"/>
    <route id="N_E" edges="N2TL TL2E"/>
    <route id="N_S" edges="N2TL TL2S"/>
    <route id="E_W" edges="E2TL TL2W"/>
    <route id="E_N" edges="E2TL TL2N"/>
    <route id="E_S" edges="E2TL TL2S"/>
    <route id="S_W" edges="S2TL TL2W"/>
    <route id="S_N" edges="S2TL TL2N"/>
    <route id="S_E" edges="S2TL TL2E"/>

After running train.py -c config.yaml, it had another error
