Undefined function or variable 'batchNorm​alizationL​ayer'.

Hi everyone,

I want to run this code form MATLAB examples, however I get this error that "Undefined function or variable 'batchNormalizationLayer'."

The code is as follow which can also be found in https://nl.mathworks.com/help/nnet/ref/nnet.cnn.layer.batchnormalizationlayer.html :

layers = [
    imageInputLayer([28 28 1])

      convolution2dLayer(3,8,'Padding',1)
      batchNormalizationLayer
      reluLayer

      maxPooling2dLayer(2,'Stride',2)

      convolution2dLayer(3,16,'Padding',1)
      batchNormalizationLayer
      reluLayer

      maxPooling2dLayer(2,'Stride',2)

      convolution2dLayer(3,32,'Padding',1)
      batchNormalizationLayer
      reluLayer

      fullyConnectedLayer(10)
      softmaxLayer
      classificationLayer];

Can someone tell me what is wrong?

Thank you in advance.

Hi, check whether you have Neural Network Toolbox installed or not. And if you have then may be it's not installed properly. Try reinstalling it.

You can view all installed toolboxes using the Add-On Manager. To open the Add-On Manager, go to the Home tab and select Add-Ons > Manage Add-Ons.

Hi, I have the toolbox installed but I still get this error. Any idea how I can solve this?
