ImportError for .cfg file when trying to run a node in ROS Kinetic

I have a .cfg file defined and set as executable in a /config folder which I have added in my CMakeList.txt as well.

In my node's python script, when I try to import the .cfg file to access some of the config parameters in a callback function for dynamic_reconfigure, I get the "No Module Named Pcl.cfg"

I am blank on what could be the problem here. Is there something else I need to specify somewhere? Like in my CMakeList?

I am trying to port some C++ code to Python, so utilizing a CMake for the node which is originally written in C++. So maybe I am missing something, but not sure what.

Would appreciate any guidance! Let me know if you need more information.

The issue was the import statement.

My .cfg file was named Pcl.cfg

And had the following in it - exit(gen.generate(PACKAGE, "test_package", "Pcl"))

I thought, as per the tutorials, I should import it based on the 3rd argument above.

So my import statement was from Pcl.cfg import PclConfig

Which was wrong. It was instead supposed to be - from test_package.cfg import PclConfig

My fault for not thoroughly going through the tutorial on this one.

Thank you for this. The tutorials are super misleading.
