Train Stacked Auto encoders for potholes datasets classification

Helo, iam working on pothole dataset image classification using train stacked auto encoders. Iam gettin few errors and iam unable to load the dataset . Could any one please help me in solving this error.

clc;
clear all;
close all;
myTrainingFolder = 'C:\Users\Admin\Desktop\Major Project\dataset';

imds = imageDatastore(myTrainingFolder,'IncludeSubfolders', true,  'LabelSource', 'foldernames');

labelCount = countEachLabel(imds);
numClasses = height(labelCount);
numImagesTraining = numel(imds.Files);
%% Create training and validation sets
[imdsTrainingSet, imdsValidationSet] = splitEachLabel(imds,0.7,'randomized');
rng('default');
hiddenSize1 = 100;
autoenc1 = trainAutoencoder(imdsTrainingSet,hiddenSize1, ...
    'MaxEpochs',400, ...
    'L2WeightRegularization',0.004, ...
    'SparsityRegularization',4, ...
    'SparsityProportion',0.15, ...
    'ScaleData', false);
view(autoenc1);
figure()
plotWeights(autoenc1);

ERROR:
