Re: [sumo-user] Taxi simulation times out in Python

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Try launching the process from python with 'sumo-gui' and check where it gets stuck.

Hi sumo users,

I created a python script to generate and execute multimodal simulation scenarios. For scenarios with a low number of taxis in the network, the code runs successfully. For scenarios with a higher number of taxis (38, for example) the configuration file cannot be run and times out. When this same configuration file is run using the command line or the GUI, however, it runs successfully.

Below is the problematic section of code. Attached is a photo of the traceback

 

cmd ='sumo -c'+file

process = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True)
try:

     process.wait(timeout=60)

except subprocess.TimeoutExpired:
     process.terminate()
     traceback.print_exc()

Note that the process timeout time of 60 was chosen to test the code. The process still does not complete after multiple hours.

Thanks as always,
