hello,

when i try to run YOLOv2 as in https://www.mathworks.com/help/deeplearning/examples/object-detection-using-yolo-v2.html

using my own dataset i got this kind of error and i don't know what;s wrong with my dataset? could anyone please explian what does this erorr mean and how can in solve it ?

Error using insertObjectAnnotation

Expected LABEL to be nonempty.

Error in insertObjectAnnotation>validateAndParseInputs (line 180)

checkLabel(label);

Error in insertObjectAnnotation (line 123)

在 MATLAB Online 中打开

I am getting the same error, but it appears when the image "highway.png" is changed for another one.

I = imread('highway.png');
I = imresize(I,inputSize(1:2));
[bboxes,scores] = detect(detector,I);

Yonathan Zarkovian, I think the error shows up when an image is not what the algorithm is waiting for. I uploaded different kind of images and only similar images to the dataset worked.
