Function Usage

Instantiates a Layout object based on the input Shape and Stride objects.

Prototype

__aicore__ inline constexpr Layout(const ShapeType& shape  = {}, const StrideType& stride = {}) : Std::tuple<ShapeType, StrideType>(shape, stride)

Parameters

Parameter	Input/Output	Description
shape	Input	Std::tuple structure type, which is used to define the logical shape of data, such as the number of rows and columns in a two-dimensional matrix or the size of each dimension in a multi-dimensional tensor.
stride	Input	Std::tuple structure type, which is used to define the stride size of each dimension in memory, that is, the interval between adjacent elements in the same dimension in memory. The interval is measured in elements and corresponds to the dimension information of the shape.

Returns

None

Restrictions

The Shape and Stride structures passed during the construction of the Layout object must be of the Std::tuple type and meet the usage restrictions of the Std::tuple structure type.

Examples

AscendC::Shape<int,int,int> shape = AscendC::MakeShape(10, 20, 30);
AscendC::Stride<int,int,int> stride = AscendC::MakeStride(1, 100, 200);

AscendC::Layout<AscendC::Shape<int, int, int>, AscendC::Stride<int, int, int>> layoutInit(shape, stride);
