data annotation for 2500+ image for yolo

Hello everyone,

I am trying to implement fire detection based on my custom dataset, I have made 2 folders i.e.fire and non fire images.
So the question is for the xml file, do I have to annotate each image manually, or there is a better and faster way to annotate.
One more thing is I want your recommendation as to which yolo version to use, v4, v5 or v7?? Any guide would be greatly helpful for a newbie like me. …
