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

YOLOv4 model detection issue on RTSP
We're using a Yolo4 (Pytorch) model to detect different barricades and cordons around some workplaces, the use case being any missing cordons/barricades at any point in time.
We're running our models on RTSP streams with full camera zoom.
However…

How would you train YoloV3 or YoloV4 on images of size 8280X6208
I am trying to train Yolo on 8k images but resizing images to 416 by 416 loses a lot of information. Is there a way to grid search on the images before passing it as training and then putting them back together after inference ?
