Struct SymDim 

pub struct SymDim(/* private fields */);

A symbolic tensor dimension expression used to build shape-agnostic graphs.

SymDim values are produced from traced tensor axes via TracedTensor::sym_size and can be combined with basic arithmetic before being passed to TracedTensor::reshape_sym.

Examples

let rows = x.sym_size(0);
let cols = x.sym_size(1);
let y = x.reshape_sym(&[rows * cols])?;

Implementations

impl SymDim

pub fn min(self, other: impl Into<SymDim>) -> Self

Return the smaller of two symbolic dimensions.

Examples

let clipped = x.sym_size(0).min(8usize);

pub fn max(self, other: impl Into<SymDim>) -> Self

Return the larger of two symbolic dimensions.

Examples

let batch = x.sym_size(0).max(1usize);
