I follow the demo of fast RCNN to study deep learning.

but erros happen.

% Read one of the images.

I = imread(vehicleDataset.imageFilename{10});

% Insert the ROI labels.

I = insertShape(I, 'Rectangle', vehicleDataset.vehicle{10});

errors:

>> insertShape(img1, 'Rectangle', vehicleDataset.vehicle{1})

Error using vision.ShapeInserter

The specified superclass 'matlab.system.SystemAdaptorSFun' contains a parse error, cannot be found on MATLAB's

search path, or is shadowed by another file with the same name.

Error in insertShape>createShapeInserter_sim (line 792)

h_ShapeInserter = vision.ShapeInserter('Shape', 'Rectangles', ...

Error in insertShape>getSystemObjects_sim (line 751)

h_ShapeInserter = createShapeInserter_sim(shape, fillShape, ...

Error in insertShape (line 114)

why?
