LoftQ Initialization

| Paper | Code | PEFT Example |

LoftQ (LoRA-fine-tuning-aware Quantization) provides a quantized backbone Q and LoRA adapters A and B, given a full-precision pre-trained weight W.

This model, Mistral-7B-v0.1-4bit-32rank, is obtained from Mistral-7B-v0.1. The backbone is under LoftQ/Mistral-7B-v0.1-4bit-32rank and LoRA adapters are under the subfolder='loftq_init'.

Model Info

Backbone

• Stored format: torch.bfloat16
• Size: ~ 14 GiB
• Loaded format: bitsandbytes nf4
• Size loaded on GPU: ~3.5 GiB

LoRA adapters

• rank: 32
• lora_alpha: 16
• target_modules: ["down_proj", "up_proj", "q_proj", "k_proj", "v_proj", "o_proj", "gate_proj"]

Usage

Training. Here's an example of loading this model and preparing for the LoRA fine-tuning.

import torch
from transformers import AutoModelForCausalLM, BitsAndBytesConfig
from peft import PeftModel

MODEL_ID = "LoftQ/Mistral-7B-v0.1-4bit-32rank"

base_model = AutoModelForCausalLM.from_pretrained(
    MODEL_ID, 
    torch_dtype=torch.bfloat16,  # you may change it with different models
    quantization_config=BitsAndBytesConfig(
        load_in_4bit=True,
        bnb_4bit_compute_dtype=torch.bfloat16,  # bfloat16 is recommended
        bnb_4bit_use_double_quant=False,
        bnb_4bit_quant_type='nf4',
    ),
)
peft_model = PeftModel.from_pretrained(
    base_model,
    MODEL_ID,
    subfolder="loftq_init",
    is_trainable=True,
)

# Do training with peft_model ...
