Re: [sumo-user] Error message from traci

[Jakob Erdmann <namdre.sumo@xxxxxxxxxxxxxx>]

It means that your script (the peer) closed the connection. This causes sumo to quit.

Try using traci.close() in your script before calling traci.start().

Thanks for help.

I did what you recommend me to and got the message below(from log.txt when it run the 5th time):

***Starting server on port 56407 ***

done (1ms).

Loading done.

I don't understand the line begin with "Error: ...".

What does it means?

Possible there is an error in 005.sumocfg which prevented the simulation from starting.

Add the option <log value="log.txt"/> to your sumocfg and then look into the generated file log.txt to check for errors.

Hello,

I wanted to use python to trigger sumo running repeatedly and automatically,
but found that it can only run the simulation for 4 times.
There's error message when it tried to run the fifth time:

Traceback (most recent call last):
  File "D:\005\runner.py", line 180, in <module>
    traci.start ([sumoBinary,
"-c","005.sumocfg","--tripinfo-output","tripinfo_005.xml","--start","--quit-on-end"])
  File "D:\sumo\tools\traci\__init__.py", line 82, in start
    sumoProcess = subprocess.Popen(cmd + ["--remote-port", str(port)])
  File
"C:\Users\Al\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",
line 596, in __init__
    _cleanup()
  File
"C:\Users\Al\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",
line 205, in _cleanup
    res = inst._internal_poll(_deadstate=sys.maxsize)
  File
"C:\Users\Al\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",
line 1035, in _internal_poll
    if _WaitForSingleObject(self._handle, 0) == _WAIT_OBJECT_0:
OSError: [WinError 6] The handle is invalid.

How can I fix it?
Thanks!

Al Lo
