How to organize the data ?

[Aysha9]

Hi,
I am new to Python and Numpy.
I would like to know how should I prepare the data to use this code please ? What should be the organization of the data inside the array ?
In my comprehension, this algorithm allows to classify images of size 227x227x(Z). How could all the images be reshape in a 111x111x111 array ? I suppose I have a wrong comprehension of the code.
Thank you very much for any help.
