How can i extract images from locations

I have 1000 images for training.

i have used imagedatastore for storing images .

after building network and diving images into testing and training. ie Xtrain,Ytrain.Xtest,Ytest where X is images with corresponding label in Y

I am unable to train.

My Xtrain Folder has locations like

ans =

5×1 cell array

{'E:\prototype\A\1.png' }

{'E:\prototype\A\10.png'}

{'E:\prototype\A\11.png'}

{'E:\prototype\A\12.png'}

{'E:\prototype\A\17.png'}

but for training this has to be image

So why does it think the PNG files are not image files?

Error using trainNetwork (line 170)

Invalid training data. Predictors must be a N-by-1 cell array of sequences, where N is the number of

sequences. All sequences must have the same feature dimension and at least one time step.

Error in net1code_naaz (line 105)

net = trainNetwork(XTrain,YTrain,layers,options);

this is the error i have got.

i am unable to train data with image locations

If you are using the following syntax for trainNetwork:

net = trainNetwork(X,Y,layers,options)

Then X should be the numeric array which contains the predictor variables and Y should be the categorical labels or numeric responses. Hence X shouldn't be the cell array which contains image locations (like in the question above).

If you are using the datastore then the following syntax must be used:

net = trainNetwork(imds,layers,options)

where imds is the imageDatastore.

Refer to the documentation of trainNetwork for more information.
