I am not able to run the code given the following link:

https://in.mathworks.com/help/deeplearning/ug/train-a-variational-autoencoder-vae-to-generate-images.html

It is showing error while loading the 'MNIST' dataset. Someone please tell me what is the format of 'XTrain' data in this code. I am trying to run this code using my own dataset. format of 'XTrain' variable using my dataset is 102x1 cell. But I am getting error in mbq = minibatchqueue(dsTrain,numOutputs, ... line. it says Conversion to single from cell is not possible. So, I need to know the format of 'XTrain' variable to remove this error. Someone please help me with this.

Hi Debojit,

The format of the XTrain variable present in the example "train a variational autoencoder vae to generate images" is of the type 4-D double which is a way to represent a four-dimensional (4-D) numerical array that stores data using double-precision floating-point numbers. Hence, due to mismatch in types you may be getting the conversion error. Hope this helps in solving your error.

Thank you for your response.

Can you provide a sample code for this conversion of XTrain (with 102x1 cell format) to four-dimensional (4-D) numerical array that stores data using double-precision floating-point numbers. I am trying to do it using reshape function but I am getting errors. If possible, please help me with this
