[sumo-user] Problems when using multiprocessing in SUMO

Hi Jakob, I need to use average SUMOs in my project,and I use traci.start([sumoBinary,"--start","-c","data/cross.sumocfg","--tripinfo-output","/home/hzq/hzq_disk2/test_A3C_tripinfo/tripinfo_%s.xml" % i_name]) to start SUMOs. And it works well,but, when I use
