YOLOv4 custom model: is final.weights or last.weights better?

Question

I'm training a custom YOLOv4 model using darknet, and at the end of training it produces two files: last.weights and final.weights. What is the difference between them, and which one should I use? From the naming I'd guess final.weights is the best best.weights that was generated, but I can't find it documented anywhere.

Answer 1

Reference to original Yolov4, last_weight is not the best

(file yolo-obj_last.weights will be saved to the build\darknet\x64\backup\ for each 100 iterations)

And if you dive into source code, final.weight is saved after training (through all iterations)
The best.weights file is exactly the best weight you need
