10,000-word long text, YOLOv8 yaml file analysis | One article handles YOLOv8 classification tasks, detection tasks, segmentation tasks, and key point tasks

I wrote a yaml file analysis of YOLOv5/v7 before , and everyone gave good feedback. This article mainly introduces YOLOv8the yamlfile,

In fact, the yaml files of the previous versions of YOLOv8v5v7 are the same as that of yaml, but after updating many versions, there have been quite big changes.

And YOLOv8this project supports a lot of algorithms and tasks, so yamlI think it is necessary to explain this document to everyone. There are many details in it. Please read it carefully. If you don’t understand, welcome to communicate in the comment area~

YOLOv8 yaml analysis

The file I am talking about here yamlis the model yamlfile, through which yamlwe can quickly understand or define our network structure,

YOLOv8Multiple versions of the network model are provided, where the model is trained on an n, s, m, l, xinput image of size , and finally the input image is down-sampled, and a prediction feature layer is output.640x640323
