It sounds like you have code in one module using an option defined
somewhere else and relying on import ordering to cause that option to be
defined. The import_opt() method of the ConfigOpts class is meant to
help make these cross-module option dependencies explicit [1]. If you
provide a more detailed traceback I may be able to give more specific
advice about where changes are needed.
