Struct PendingIsqLayer 

pub struct PendingIsqLayer { /* private fields */ }

A wrapper around a QuantMethod that resolves lazily from a background quantization task. Created by apply_immediate_isq when a thread pool is available for parallel immediate ISQ.

Trait Implementations

impl Debug for PendingIsqLayer

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

Formats the value using the given formatter.

impl QuantMethod for PendingIsqLayer

fn new(_method: QuantMethodConfig) -> Result<Self>

where Self: Sized,

fn dequantize_w(&self) -> Result<Tensor>

fn forward(&self, a: &Tensor) -> Result<Tensor>

Compute matmul of self and a. self should contain the weights.

fn forward_autocast(&self, a: &Tensor) -> Result<Tensor>

Compute matmul of self and a. self should contain the weights. Automatically cast to required quantization activation type and back

fn gather_forward_autocast( &self, a: &Tensor, indices: &Tensor, ) -> Result<Tensor>

Compute matmul of self and a. self should contain the weights. Automatically cast to required quantization activation type and back.

fn gather_forward(&self, a: &Tensor, indices: &Tensor) -> Result<Tensor>

Compute matmul of self and a. self should contain the weights.

fn quantized_act_type(&self) -> Option<DType>

If a quantized method, return the activation dtype.

fn dtype_and_device(&self) -> (DType, Device)

Weight dtype and device

fn add_delta_w(&self, delta: &Tensor) -> Result<Arc<dyn QuantMethod>>

Add a delta weight from LoRA to the weights. This should be prescaled with alpha.
