Error using permute in CNN

Hello

Greetings from Mexico.

My problem is the next:

I saw a webinar posted in:

https://la.mathworks.com/matlabcentral/fileexchange/57116-deep-learning-for-computer-vision-demo-code?s_tid=prof_contriblnk

I have an error and I do not know how to solve it, could you help me by giving me an orientation?

The error is in the following lines:

Error using permute

ORDER must have at least N elements for an N-D array.

Error in classreg.learning.internal.orientX (line 13)

X = permute(X , [2 1 3])

Error in classreg.learning.classif.CompactClassificationECOC/predict (line 324)

[X,varargin] = classreg.learning.internal.orientX(...

Error in PetDetectionRecognitionScript (line 96)

predictedLabels = predict(classifier, testFeatures);

I have Matlab 2018b update 4 in Win 10 64 bit ......

Any help ? pls....

Greetings and thanks in advance
