Struct QLoraLayer

Source

pub struct QLoraLayer { /* private fields */ }

Expand description

QLoRA adapter wrapping a model’s linear layers.

Implementations§

Source §

impl QLoraLayer

Source

pub fn new(linear: QuantizedLinear) -> QLoraLayer

Create a new QLoRA layer.

Source

pub fn forward(&self, input: &Tensor) -> Result<Tensor, QLoraError>

Forward pass.

§Errors

Returns error if the underlying linear layer forward fails

Source

pub fn quantized_weight(&self) -> &QuantizedTensor

Get a reference to the quantized base weight tensor.

Source

pub fn lora_weights(&self) -> (&Tensor, &Tensor)

Get the LoRA A and B weight tensors.

Returns (lora_a, lora_b) where:

lora_a has shape [r, in_features]
lora_b has shape [out_features, r]

Source

pub fn lora_scale(&self) -> f64

Get the LoRA scaling factor (alpha / rank).

Source

pub fn device(&self) -> &Device

Get the device used by this layer.

Source

pub fn config(&self) -> &QLoraConfig

Get the quantization configuration.
