You didn't describe you you created the necessary __init__.py files.
If they are not empty, there is a good chance that you made some
error in creating these files.

What is the error that you get with the circular imports?

One reason is that there could be duplicate module names, e.g. overlaps
with the standard library. When you fully-qualified the modules, you
actually changed the program, which would now import the user-provided
modules instead of the predefined ones.
