Error related to datasets when using yolov2.

hello!

I changed the training data using the form shown at this address(https://kr.mathworks.com/help/deeplearning/ug/object-detection-using-yolo-v2.html?searchHighlight=yolo&s_tid=srchtitle_yolo_6), but just before the training, the same phenomenon as the picture below appeared, so I'm not sure what the problem is.

There is no problem with the name and label of the video, but I don't know what went wrong.

Please help me who lacks knowledge about matlab.

Thans you so much. Have a nice day everyone~

yes，sir，as the information，please make your image to rgb not gray，such as

augimdsTrain = augmentedImageDatastore(inputSize(1:2),imdsTrain,'ColorPreprocessing','gray2rgb');

or use

img = cat(3,im,im,im);

to make 3 channel，just as rgb format
