AttributeError: module 'traci' has no attribute 'sumolib'

CARLA version: 0.9.13 Platform/OS: Linux

Hi there,

when i use sumo to run a co-simulation example in the carla-0.9.13/Co-Simulation/Sumo/examples folder , and it can run with no error.

But when i use my own .rou.xml file and .sumocfg file to run co-simulation, it said that in /Co-Simulation/Sumo/sumo_integration/sumo_simulation.py", line 304, , `module 'traci' has no attribute 'sumolib'

After i change the line 304 traci.sumolib.net.readNet(net_file) to sumolib.net.readNet(net_file) and no error is reported and the system works normally, and i wanna know is there a small bug in sumo_simulation.py?

You can try to check the versions of sumo,the new version is different

You can change traci.sumolib.net.readNet to sumolib.net.readNet to fix the error.

File "/Carla/Co-Simulation/Sumo/sumo_integration/sumo_simulation.py", line 304, in _get_sumo_net sumo_net = traci.sumolib.net.readNet(net_file) AttributeError: module 'traci' has no attribute 'sumolib'

最终是找到了问题所在：

这是因为sumolib是独立的包，不在traci里面，你需要把carla/Co-Simulation/Sumo/sumo_integration/sumo_simulation.py的304行的这一句代码改成sumo_net = sumolib.net.readNet(net_file)

You can change traci.sumolib.net.readNet to sumolib.net.readNet to fix the error.

Can confirm this is still the case.
