Hello
Can anyone please help me with resolving this error message?
The error message occurs after uploading the network to the deep network designer application
Thank you
My code:
clear all

format long g
data=load('matlab_V21_ROI_11_3_2021.mat')
gTruth=data.gTruth;
gTruth.DataSource
gTruth.LabelDefinitions;
replaceimds=imageDatastore('C:\monika\vse\kratery')
replaceDataSource=groundTruthDataSource(replaceimds)
gTruth.DataSource=replaceDataSource

for k = 1:maxNumAnchors
% Estimate anchors and mean IoU.
[anchorBoxes{k},meanIoU(k)] = estimateAnchorBoxes(cds,k);
end

Deep Network Designer currently doesn't support training of a network with multiple outputs.
To train Faster R-CNN, you could use the trainFasterRCNNObjectDetector function as shown in this example.
