DML_DEPTH_SPACE_ORDER enumeration (directml.h)

  • Article

Defines constants controlling the transform applied in the DirectML operators DML_OPERATOR_DEPTH_TO_SPACE1 and DML_OPERATOR_SPACE_TO_DEPTH1. These are used within the DML_DEPTH_TO_SPACE1_OPERATOR_DESC and DML_SPACE_TO_DEPTH1_OPERATOR_DESC structures.

Syntax

typedef enum DML_DEPTH_SPACE_ORDER {
  DML_DEPTH_SPACE_ORDER_DEPTH_COLUMN_ROW,
  DML_DEPTH_SPACE_ORDER_COLUMN_ROW_DEPTH
} ;

Constants

 
DML_DEPTH_SPACE_ORDER_DEPTH_COLUMN_ROW
Causes tensors used in DML_DEPTH_TO_SPACE1_OPERATOR_DESC and DML_SPACE_TO_DEPTH1_OPERATOR_DESC to be interpreted with the following layouts, where dimensions in parenthesis are flattened together.

- Depth version: [Batch, (BlockHeight, BlockWidth, Channels), Height, Width]
- Space version: [Batch, Channels, (Height, BlockHeight), (Width, BlockWidth)]
DML_DEPTH_SPACE_ORDER_COLUMN_ROW_DEPTH
Causes tensors used in DML_DEPTH_TO_SPACE1_OPERATOR_DESC and DML_SPACE_TO_DEPTH1_OPERATOR_DESC to be interpreted with the following layouts, where dimensions in parenthesis are flattened together.

- Depth version: [Batch, (Channels, BlockHeight, BlockWidth), Height, Width]
- Space version: [Batch, Channels, (Height, BlockHeight), (Width, BlockWidth)]

Remarks

See DML_DEPTH_TO_SPACE1_OPERATOR_DESC and DML_SPACE_TO_DEPTH1_OPERATOR_DESC documentation for examples showing the effect of these values.
