Struct NasGenome 

pub struct NasGenome<B: Backend> { /* private fields */ }

One population’s worth of architecture-NAS genomes.

arch_ids[i] is the architecture index of individual i (in 0..num_variants); row i of weights holds that individual’s flat weight vector, padded with trailing zeros out to max_param_count.

Not Clone

NasGenome deliberately does not derive Clone: Burn tensors alias their underlying storage, so a derived Clone would silently share buffers rather than copy them. ArchNasStrategy::ask constructs a fresh NasGenome with newly allocated tensors (built host-side via Tensor::from_data) instead of cloning the struct — consistent with WeightOnly and the phase-1 strategies.

Implementations

impl<B: Backend> NasGenome<B>

pub fn try_new( arch_ids: Vec<usize>, weights: Tensor<B, 2>, ) -> Result<Self, ConfigError>

Assembles a population genome, checking one architecture id per row.

Errors

Returns a ConfigError if weights has zero rows or if arch_ids does not have exactly one entry per weight row (pop_size).

pub fn arch_ids(&self) -> &[usize]

Architecture index of each individual, length pop_size.

pub fn weights(&self) -> &Tensor<B, 2>

Per-individual flat weights, shape [pop_size, max_param_count].

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
