I am running ROS Indigo on Ubuntu 14.04. Here is my package and cmake file:

CMAKELIST:

cmake_minimum_required(VERSION 2.8.3)
project(semantic_label_publisher)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS
  rospy
  std_msgs
  message_generation
)


## Generate messages in the 'msg' folder
 add_message_files(
   FILES
   SemLabel.msg
#   Message2.msg
 )

## Generate services in the 'srv' folder
# add_service_files(
#   FILES
#   Service1.srv
#   Service2.srv
# )

## Generate actions in the 'action' folder
# add_action_files(
#   FILES
#   Action1.action
#   Action2.action
# )

## Generate added messages and services with any dependencies listed here
 generate_messages(
   DEPENDENCIES
   std_msgs  # Or other packages containing msgs
 )

I built my package, did everything, but when I run

rosrun semantic_label_publisher semantic_label_publisher_node.py

I get the following error:

ImportError: No module named semantic_label_publish.msg

Is there something I am doing wrong? If you need anymore info let me know.

Thanks

have you sourced the setup.bash for your workspace?

Yes, first check, that you didn't forget to source devel/setup.bash. My guess would be, that you are trying to import in python by name semantic_label_publish.msg (as it says in the error), but your module has name - semantic_label_publishER (as it says in CMakeLists and package.xml)

@spooner-dev I can't believe this! You're damn right, I am supposed to run semantic_label_publisher.

I am an idiot. Thank you.

I suggest to try in your script to import:

from semantic_label_publisher.msg import SemLabel
