public class Layout
extends Wrapper
```
Layout represents the text information of tensor's dimensions/axes. E.g. layout `NCHW` means that 4D tensor `{-1, 3, 480, 640}` will have:
- 0: `N = -1`: batch dimension is dynamic
- 1: `C = 3`: number of channels is '3'
- 2: `H = 480`: image height is 480
- 3: `W = 640`: image width is 640
Examples: `Layout` can be specified for:
- Preprocessing purposes. E.g.
  - To apply normalization (means/scales) it is usually required to set 'C' dimension in a layout.
  - To resize the image to specified width/height it is needed to set 'H' and 'W' dimensions in a layout
  - To transpose image - source and target layout can be set (see `ov::preprocess::PreProcessSteps::convert_layout`)
- To set/get model's batch (see Model.get_batch()/'set_batch') it is required in general to specify 'N' dimension
in layout for appropriate inputs
