How to use the quasimodo.quasimodo_optimization.scripts.rosbag_player.RosbagPlayerServer function in quasimodo

rate.sleep()

        elif goal.command == "stop":
            #stop to record the topics
            rospy.loginfo('now the topic playing should stop')
            rospy.loginfo(self.p.pid)
            os.killpg(os.getpgid(self.p.pid), signal.SIGINT)

            rospy.loginfo("I'm done")

        else:
            rospy.loginfo('goal.command is not valid')

if __name__ == '__main__':
    rospy.init_node('rosbag_player')
    RosbagPlayerServer(rospy.get_name())
    rospy.spin()
