Hello guys i'm trying this code and i don't know what to do to fix the problem
data = load('Damagevehicle.mat');
trainingData = data.Damaaaage;
rng(0);
shuffledIdx = randperm(height(trainingData));
trainingData = trainingData(shuffledIdx,:);
imds = imageDatastore(trainingData.imageFilename);
blds = boxLabelDatastore(trainingData(:,2:end));
ds = combine(imds, blds);
net = load('yolov2VehicleDetector.mat');
lgraph = net.lgraph;
lgraph.Layers;
options = trainingOptions('sgdm','InitialLearnRate',0.001,...
'Verbose',true,'MiniBatchSize',32,'MaxEpochs',30,...
'Shuffle','never','VerboseFrequency',30,...
'CheckpointPath',tempdir);
[detector,info] = trainYOLOv2ObjectDetector(ds,lgraph,options);
The error i got:
Invalid transform function defined on datastore.
The cause of the error was:
Error using vision.internal.cnn.validation.checkTrainingBoxes (line 12)
Training data from a read of the input datastore contains invalid bounding boxes. Bounding boxes must be non-empty,
fully contained within their associated image and must have positive width and height. Use datastore transform method
and remove invalid bounding boxes.
