Hi,

I am having a hard time making my python code execute with rosrun. My project structure looks like this: ~/workspace/src/my_package which contains two subdirectories with my code, lets say a with contains main.py and b with contains b.py. Each folder contains (my_package, a and b) contains a __init__.py.

In main.py, I have from b.b import ClassName

When I try to run my module with rosrun my_package main.py, I get the following error: "ImportError: No module named b"

I have a setup.py at the root of my_package:

#!/usr/bin/env python
# ! DO NOT MANUALLY INVOKE THIS setup.py, USE CATKIN INSTEAD

from distutils.core import setup
from catkin_pkg.python_setup import generate_distutils_setup

# fetch values from package.xml
setup_args = generate_distutils_setup(
    packages=['my_package'],
    package_dir={'': 'src'}
)

setup(**setup_args)

I also added the line in the CMakeLists.txt that execute it.

Any ideas?

Thank you
