TensorLayout

Enum TensorLayout 

Source
pub enum TensorLayout {
    Nchw,
    Nhwc,
    Ncdhw,
    Ndhwc,
    RowMajor,
}
Expand description

Memory layout convention for multi-dimensional tensors.

The layout determines how logical indices map to linear memory offsets. NHWC layouts are generally preferred on modern NVIDIA GPUs because they enable Tensor Core utilisation, while NCHW is the traditional PyTorch default.

Variants§

§

Nchw

Batch, Channels, Height, Width – PyTorch default.

§

Nhwc

Batch, Height, Width, Channels – Tensor Core optimal.

§

Ncdhw

Batch, Channels, Depth, Height, Width – 3-D volumetric.

§

Ndhwc

Batch, Depth, Height, Width, Channels – 3-D channels-last.

§

RowMajor

Generic row-major layout for 2-D tensors (matrices) and MoE intermediates.

Implementations§

Source§

impl TensorLayout

Source

Source

pub const fn expected_ndim(self) -> usize

Returns the expected number of tensor dimensions (including N and C).

Source

pub const fn is_channels_last(self) -> bool

Returns true if this layout places channels last (NHWC or NDHWC).
