Hello,

Thank you for the observation. I'm using SUMO v0.32.
It looks like they changed some Traci methods on v1.10 and both versions are not compatible.
For now I will keep using v0.32, but change it for v1.10 is problably a matter of changing a few lines of code.

Regards,
Lucas

The code for now is different. But I also met this error when I tried to use that in colab. Do you know the reason?
In the traffic_signal.py file, the line has changed to logic = traci.trafficlight.Logic("new-program"+self.id, 0, 0, phases=self.phases)
And there is no phases in the ql_single-intersection.py file.
