I am encountering the same error. Did you ever figure this out?

Sorry, It's too long time ago. I can't remember the details about how to figure it out. But I think it is related to multiple versions of python on one PC. When you edit py files, make sure it is always using python interpreter python2.7. You can have a try.

If it stills acts badly, you can have another thread to ask about this. I am still confused. Maybe some onther guy will give you an answer.

Thanks for your response.

In my case I needed to alter my import statement in the service.py to from (package_name).srv import *. I had changed this line earlier while debugging a different problem.
