Even if your import had worked, this would be wrong. You're importing
everything from Sub_Dir.My_Class, so My_Class_Connector is in the current
namespace. You don't need to add "My_Class." on the front (and in fact
it's an error to do so.)

Is there a file named __init__.py in Sub_Dir? A directory must contain
that file in order to be considered a "module". (If you don't know what
to put in the file, just leave it empty.)
