I want to include a large python module (Yolov7 - https://github.com/WongKinYiu/yolov7.git) into my already existing ROS package. The large python module consists of many files which depend on each other. I want this to be included and available for use in my main program scripts/main.py, which runs as a ROS node. This means I only want access to the functions, not create an entire new node itself.

File structure: https://imgur.com/a/THP5WvP

PROBLEM: Files in yolov7 including other files in yolov7 need to have the path name package.yolov7.filename, while the whole module is actually written on the form: **from filename import ...**

How can I make sure files in yolov7 actually can import other files in yolov7 without having to add the extra path to every import?

Example: instead of having to write: from package.yolov7.utils.datasets import letterbox

I want to be able to have: from utils.datasets import letterbox

I have tried editing CMakeLists.txt, setup.py, and package.xml, but for now they are unchanged in regards to yolov7.

I'm using ROS Noetic, running Ubuntu 5.4.123.
