Merging YOLOv5 Models for Custom and COCO Classes

[hariteja2408]

I have two YOLOv5 pre-trained models: best1.pt, trained on a custom dataset with 4 classes, and yolov5s.pt, trained on the 80 classes of the COCO dataset. I aim to merge these models to create one capable of detecting both the custom classes and the "person" class from COCO. What is the recommended approach for achieving this? Additionally, could you provide insights on potential challenges and optimal methods for model fusion?
