I've encountered an issue with dynamic_reconfigure (working with python) not producing an __init__.py in the configuration module directory:

As expected, the generator produces a new directory my_module (with a cfg directory within) in my src directory. It does create an __init__.py file within the cfg directory but not within my_module itself. Python doesn't recognize this as a module and I get the following error:

ImportError: No module named my_module.cfg

Manually creating an __init__.py file within the my_module directory solves this problem. Is anyone else encountering this issue? Is it a bug or do I have a setting wrong somewhere? Thanks in advance!

System: Ubuntu 10.10, Python Version: 2.7.1, ROS Electric and Diamondback

I have the same issue here (Ubuntu 11.04; Python 2.7.1; ROS electric).

We have the same issue here. It seems the cause is `rosed dynamic_reconfigure parameter_generator.py` fail to generate the necessary __init__.py. Ticket submitted https://code.ros.org/trac/ros-pkg/ticket/5259

If you suffer from this in, e.g., mypackage, go to mypackage/src/mypackage, and touch __init__.py

For example:

rosmake mypackage
roscd mypackage/src/mypackage 
touch __init__.py

Then it should run.

This is a useful temporary workaround, but not a fix for the problem, which will recur when someone else checks out mypackage.

This may be a bug. Please open a ticket.

I have not seen it, perhaps because I already had a src/my_package/__init__.py for other reasons.
