while rinning the example "ObjectDetectionUsingYOLOV3DeepLearningExample.mlx"
it stopes at line 48
yolov3Detector = yolov3ObjectDetector(baseNetwork, classNames, anchorBoxes, 'DetectionNetworkSource', {'fire9-concat', 'fire5-concat'});
this error appears
unrecognized function or variable 'yolov30ObjectDetector
Did you mean:
yolov3Detector = yolov2ObjectDetector(baseNetwork, classNames, anchorBoxes, 'DetectionNetworkSource', {'fire9-concat', 'fire5-concat'});
what should I do to solve this error
where to find yolov3ObjectDetector file

This example you're executing, requires the Computer Vision Toolbox™ Model for YOLO v3 Object Detection. You can download & install the Computer Vision Toolbox Model for YOLO v3 Object Detection from Add-On Explorer or from this link.

After I install Computer Vision Toolbox™ Model for YOLO v3 Object Detection in R2021b, then I find yolov3ObjectDetector at
fullfile(matlabshared.supportpkg.getSupportPackageRoot, 'toolbox', 'vision', 'supportpackages', 'yolov3', 'yolov3ObjectDetector.m')
for example
/Users/roberson/Documents/MATLAB/SupportPackages/R2021b/toolbox/vision/supportpackages/yolov3/yolov3ObjectDetector.m

that didn't help. After downloading this package, while installing it I got this error: The support package is not compatible with your version of MATLAB or operating system

Have you solved this problem? I have already update my MATLAB version to R2021a, but still have this problem.
Could you give the yolov3ObjectDetector? Thanks!
