Hello,
I am currently using sumo to do research with A3C. However, when I was
trying to use multi-clients with the method from sumo documentation, it
always shows 'waiting for clients'. Could you please help me with this?
Below is my code.
try:
sys.path.append(os.path.join(os.path.dirname(
__file__), '..', '..', '..', '..', "tools")) # tutorial in
tests
sys.path.append(os.path.join(os.environ.get("SUMO_HOME",
os.path.join(
os.path.dirname(__file__), "..", "..", "..")), "tools")) #
tutorial in docs
from sumolib import checkBinary # noqa
from sumolib.miscutils import getFreeSocketPort
except ImportError:
sys.exit(
"please declare environment variable 'SUMO_HOME' as the
root directory of your sumo installation (it should contain folders 'bin',
'tools' and 'docs')")
PORT = 8813
sumoBinary = checkBinary('sumo-gui')
#client1
# PORT = int(sys.argv[1]) # example
traci.start([sumoBinary, "-c", "fixed_avg.sumocfg", "--num-clients", "2"],
port=PORT)
traci.setOrder(1) # number can be anything
while traci.simulation.getMinExpectedNumber() > 0:
traci.simulationStep()
# more traci commands
traci.close()
# client2
# PORT = int(sys.argv[1]) # example
traci.init(PORT)
traci.setOrder(2) # number can be anything as long as each client gets its
own number
while traci.simulation.getMinExpectedNumber() > 0:
traci.simulationStep()
# more traci commands
traci.close()
Thank you very much!
Best,
Lewis
