Error using dlquantizer - Deep Network Quantizer

Question

Hi,

I have trained a SqueezeNet neural network, using MATLAB Deep Network Designer and now I want to quantize the network for fixed-point applications.

I've tried following the 'Import a dlquantizer Object into the Deep Network Quantizer App' example found here: https://uk.mathworks.com/help/deeplearning/ref/deepnetworkquantizer-app.html

but I get the following error:

Error using dlquantizer

Unable to resolve the name dltargets.internal.validateNetwork.

Error in deepNetQuant (line 9)

quantObj = dlquantizer(net);

The code I'm running is as follows;

net = trainedNetwork_2
imds = trafficSignImds;
[calData, valData] = splitEachLabel(imds, 0.8, 'randomized')
aug_calData = augmentedImageDatastore([227 227], calData)
aug_valData = augmentedImageDatastore([227 227], valData)
quantObj = dlquantizer(net);
calResults = calibrate(quantObj, aug_calData);
