how to solve "Dot Indexing not supported for this type of variable" error

I trained a Faster R-CNN network by following the trainfasterrcnn page but i am unable to test the network as i get the error below

"Dot indexing is not supported for variables of this type.

Error in fasterRCNNObjectDetector/parseDetectInputs (line 713)

networkInputSize = this.Network.Layers(this.LayerIndices.ImageLayerIdx).InputSize;

Error in fasterRCNNObjectDetector/detect (line 441)

params = this.parseDetectInputs(I, varargin{:});"

    % load training data
load('FiveClassesTraining.mat');
TestImg = imread(trainingData.Imagefilename{70});
figure
imshow(TestImg)

% Run the detector  
[bboxes,scores] = detect(detector,TestImg);

% Annotate detections in the image.
TestImg = insertObjectAnnotation(TestImg,'rectangle',bboxes,scores);
figure
imshow(TestImg)

Thanks Walter, it is

'fasterRCNNObjectDetector'

Please attach your .mat and a sample image for us to test with.

Thank you so much for the help, kindly find attached the mat file and a sample image

[Walter Roberson]

The detector object in that .mat file is empty. It exists, but it has no model name, no weights, everything empty.

will check it out.. Thanks
