e.g. for data_format = NHWC,
     Each element in the input tensor can be specified via 6 coordinates,
     ordered by decreasing memory layout significance as:
     n,iY,iX,bY,bX,oC  (where n=batch index, iX, iY means X or Y coordinates
                        within the input image, bX, bY means coordinates
                        within the output block, oC means output channels).
