StaticReshape#

General#

StaticReshape operation changes dimensions of \(\src\) tensor according to the specified shape. The volume of \(\src\) is equal to \(\dst\), where volume is the product of dimensions. \(\dst\) may have a different memory layout from \(\src\). StaticReshape operation is not guaranteed to return a view or a copy of \(\src\) when \(\dst\) is in-placed with the \(\src\). StaticReshape can be used where if shape is stored in a constant node or available during graph building stage. Then shape can be passed via shape attribute.

Operation attributes#

Attribute Name

Description

Value Type

Supported Values

Required or Optional

shape

Denotes the shape of the dst tensor.

s64

A s64 list containing positive values.

Required

special_zero

Controls how zero values in shape are interpreted.

bool

true , false

Required

Note

shape : dimension -1 means that this dimension is calculated to keep the same overall elements count as the src tensor. That case that more than one -1 in the shape is not supported.

Note

special_zero : if false, 0 in the shape is interpreted as-is (for example a zero-dimension tensor); if true, then all 0 s in shape implies the copying of corresponding dimensions from src into dst.
