'unrecognized function or variable 'yolov30ObjectDetector'

while rinning the example "ObjectDetectionUsingYOLOV3DeepLearningExample.mlx"

from this page https://www.mathworks.com/help/vision/ug/object-detection-using-yolo-v3-deep-learning.html

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

Del link: https://la.mathworks.com/matlabcentral/fileexchange/87959-computer-vision-toolbox-model-for-yolo-v3-object-detection?s_tid=srchtitle, click en "Download". Luego ir a tu descarga (yolov3.mlpkginstall) instalarlo. A mí me funcionó. Good Luck

[Subhadeep Koley]

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.

[besbesmany besbesmany]

the toolbox hanged laptop in "configuring your installatioin" step but I found it installed

when I run file "ObjectDetectionUsingYOLOV3DeepLearningExample.mlx"

it gives error at this line

unzip vehicleDatasetImages.zip

an internal error has occured.

and the vehicleDatasetImages.zip exist at folder '%examples\deeplearning_shared\data%'

how to fix and run program please

[Walter Roberson]

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

Answer 3

[Rajesh Roy]

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

[Vivek Akkala]

Computer Vision Toolbox™ Model for YOLO v3 Object Detection is Compatible with R2021a. You need to update your MATLAB version if it isn't R2021a.

[Brianna WANG]

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!
