I am struggling to progress the error (below) which I have encountered when completing this part of the tutorial link text

I'm not sure why the script I have literally copied over won't work. I have spent an hour or so trying to figure it out but can't solve it..

The code message:

danny@danny:~/catkin_ws$  rosrun beginner_tutorials add_two_ints_server.py
Traceback (most recent call last):
  File "/home/danny/catkin_ws/src/beginner_tutorials/scripts/add_two_ints_server.py", line 3, in <module>
    from beginner_tutorials.srv import *
ImportError: No module named srv
danny@danny:~/catkin_ws$

After compile your package/service with catkin_make, try to source catkin_ws/devel/setup.bash and see if it works.

We'll need more to go off of than what you've given us. Are you going through the tutorials in order? Did you go through the Creating a ROS msg and srv and Writing a Simple Service and Client (Python) tutorials before trying run that particular tutorial? If you didn't do both of those then you will get that error.

You should create a new question and reference this one

@CubeC, comments are an inappropriate place to solve problems like that. Please create a new question, it's easier to work on a problem and it will get more visibility than using comments
