lora_mistral_7b¶
- torchtune.models.mistral.lora_mistral_7b(lora_attn_modules: List[Literal['q_proj', 'k_proj', 'v_proj', 'output_proj']], apply_lora_to_mlp: bool = False, apply_lora_to_output: bool = False, lora_rank: int = 8, lora_alpha: float = 16, quantize_base: bool = False) TransformerDecoder[source]¶
Builder for creating a Mistral 7B model with LoRA enabled.
- Parameters:
lora_attn_modules (List[LORA_ATTN_MODULES]) – list of which linear layers LoRA should be applied to in each self-attention block. Options are
{"q_proj", "k_proj", "v_proj", "output_proj"}.apply_lora_to_mlp (bool) – whether to apply LoRA to the MLP in each transformer layer. Default: False
apply_lora_to_output (bool) – whether to apply LoRA to the model’s final output projection. Default: False
lora_rank (int) – rank of each low-rank approximation
lora_alpha (float) – scaling factor for the low-rank approximation
quantize_base (bool) – Whether to quantize base model weights
- Returns:
Instantiation of Mistral 7B model with LoRA applied
- Return type:
