Why do I get a warning While loading an object of class 'nnet.cnn.​TrainingOp​tionsADAM' ?

Dear Experts,

I need your help! Can you tell me how to correct the following problem?

Warning: While loading an object of class 'nnet.cnn.TrainingOptionsADAM':
The value of 'ValidationData' is invalid. Unable to read file: 'C:\ZELE\KJ\ds1\jk.png'. 
> In Az1 (line 4) 
Error using Az1 (line 14)
Out of memory on device. To view more detail about available memory on the GPU, use 'gpuDevice()'. If the problem persists, reset the GPU by calling 'gpuDevice(1)'.

Note that I do not have the problem of the memory on my device - see below
