Accessing to Autoware_msgs/Vehicle_Status

edit

Hello,

I am using Autoware.ai at the moment and I am trying to use the VehicleStatus Message from the Autoware_msgs. I want to send breakpedal, drivepedal and steering angle state via UDP to another computer. For that i wrote a Python script. I am using Ros-melodic on an Ubuntu 18.04 system. My Code:

    #!/usr/bin/env python

import rospy
import socket
import sys
import time
import struct


from nav_msgs.msg import Odometry
from autoware_msgs import VehicleStatus



def VehicleStatusCb(msg):
    values = (msg.drivepedal)
    rospy.loginfo(values)


if __name__ == "__main__":
    rospy.init_node('VVehicleStatus', anonymous=True) #make node 
    rospy.Subscriber('vehicle_status',VehicleStatus,VehicleStatusCb)
    rospy.spin()

when trying to launch the script with with rosrun i receive the following error:

Traceback (most recent call last):
  File "/home/ad-ros/catkin_ws/src/beginner_tutorials/scripts/listener.py", line 11, in <module>
    from autoware_msgs import VehicleStatus
ImportError: cannot import name VehicleStatus

I think I installed the autoware_msgs correctly because with

rosmsg info

I can see the autoware messages and during built autoware_msgs_generate_py is executed. In fact that is my first post on the forum I hopefully gave all the information you need if not please tell me what is needed in addition.
