Yolov5Net contains two COCO pre-defined models: YoloCocoP5Model, YoloCocoP6Model.

If you have custom trained model, then inherit from YoloModel and override all the required properties and methods. See YoloCocoP5Model or YoloCocoP6Model implementation to get know how to wrap your own model.

using var image = await Image.LoadAsync<Rgba32>("Assets/test.jpg");
    using var scorer = new YoloScorer<YoloCocoP5Model>("Assets/Weights/yolov5n.onnx");
        var predictions = scorer.Predict(image);

        var font = new Font(new FontCollection().Add("C:/Windows/Fonts/consola.ttf"), 16);

        foreach (var prediction in predictions) // draw predictions
            var score = Math.Round(prediction.Score, 2);

            var (x, y) = (prediction.Rectangle.Left - 3, prediction.Rectangle.Top - 23);
