Hi,
i don't know if you can help me.
I have two different python scripts.
One to start sumo with this function (works very fine):
def runLocal(self):
sumoBinary = "F:/Projektgruppe/Sumo/bin/sumo-gui"
sumoProcess = subprocess.Popen([sumoBinary, "-c",
"F:/Projektgruppe/SVN/PG_SVN/de.uniol.inf.is.odysseus.pgtaxi/scenario/oldenburg.sumocfg",
"--remote-port", str(PORT)], stdout=sys.stdout, stderr=sys.stderr)
And one with this function to connect with traci:
def initTraci(self):
tools = "F:/Projektgruppe/Sumo/tools"
sys.path.append(tools)
import traci
traci.init(PORT)
step = 0
while step < 1000:
traci.simulationStep()
print step
step += 1
traci.close()
sys.stdout.flush()
At the first step i start the script to run sumo and after this i want to start
the connect script.
Sometimes this works very fine but sometimes i get this error:
Exception in thread "MainThread" Traceback (most recent call last):
File
"C:\Users\Frederik\workspaceOdysseus\de.uniol.inf.is.odysseus.pgtaxi\src\de\uniol\inf\is\odysseus\pgtaxi\traci\traci4python\connect.py",
line 35, in <module>
conn.initTraci()
File
"C:\Users\Frederik\workspaceOdysseus\de.uniol.inf.is.odysseus.pgtaxi\src\de\uniol\inf\is\odysseus\pgtaxi\traci\traci4python\connect.py",
line 23, in initTraci
traci.init(PORT)
File "F:\Projektgruppe\Sumo\tools\traci\__init__.py", line 65, in init
return getVersion()
File "F:\Projektgruppe\Sumo\tools\traci\__init__.py", line 82, in getVersion
return _connections[""].getVersion()
AttributeError: 'NoneType' object has no attribute 'getVersion'
Especially this error occur if i want to start the script with the python
interpreter in java (later i need the return data in java):
String script_dir = System.getProperty("user.dir");
script_dir = script_dir +
"\\src\\de\\uniol\\inf\\is\\odysseus\\pgtaxi\\traci\\traci4python\\connect.py";
RunPython ie = new RunPython();
ie.execfile(script_dir);
Greetings
