[sumo-user] Problem with python code

[ali mirzaei <alimrz222@xxxxxxxxx>]

Hi everyone,

I don't know why I am not able to run my file from python while it works normally from GUI.

Here is my simple code:

1. if 'SUMO_HOME' in os.environ:
2.      tools = os.path.join(os.environ['SUMO_HOME'], 'tools')
3.      sys.path.append(tools)
4. else:
5.      sys.exit("please declare environment variable 'SUMO_HOME'")from sumolib import checkBinary
6. from sumolib import checkBinary 
7. sumoBinary = checkBinary('sumo-gui')
8. sumoCmd = [sumoBinary, "-c", "ali_trace.sumocfg"]
9. import traci
10. traci.start(sumoCmd)
11. step = 0
12. while step < 100:
13.  traci.simulationstep()
14. step += 1
15. traci.close()

The GUI is opened but nothing is shown as expected simulation. Just these messages are added at the bottom of GUI:

***Starting server on port 6269 ***
Loading net-file from 'D:\ali mirzaei\app\my_sumo\ali_trace.net.xml' ... done (3ms).
Loading is done.
Simulation started with time: 0.00

 

I would be thankful if one can help me.

Regards,

Ali
