Model Card for margin_reg_baseline_code_20260328_121558

This model is a fine-tuned version of meta-llama/Llama-3.1-8B-Instruct. It has been trained using TRL.

Quick start

python

import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification
from peft import PeftModel, PeftConfig

# -----------------------------
# 1. Define PEFT model ID & Checkpoint (Epoch)
# -----------------------------
peft_model_id = "xxccho/margin_reg_baseline_code"

# [ Checkpoints to Epochs Mapping ]
# Epoch 1  : "checkpoint-246"
# Epoch 2  : "checkpoint-492"
# Epoch 3  : "checkpoint-738"
# Epoch 4  : "checkpoint-984"
# Epoch 5  : "checkpoint-1230"
# Epoch 6  : "checkpoint-1476"
# Epoch 7  : "checkpoint-1722"
# Epoch 8  : "checkpoint-1968"
# Epoch 9  : "checkpoint-2214"
# Epoch 10 : "checkpoint-2460"

# 예시: 5 Epoch 체크포인트를 사용하려면 "checkpoint-1230" 할당. None일 시 최종(10x) 모델 로드
checkpoint = None  

# 2. Load the PEFT config
config = PeftConfig.from_pretrained(peft_model_id, subfolder=checkpoint) if checkpoint else PeftConfig.from_pretrained(peft_model_id)

# 3. Load tokenizer
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path)
if tokenizer.pad_token is None:
    tokenizer.pad_token = tokenizer.eos_token

# 4. Load base model
base_model = AutoModelForSequenceClassification.from_pretrained(
    config.base_model_name_or_path,
    num_labels=1,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

# 5. Apply LoRA adapter
model = PeftModel.from_pretrained(base_model, peft_model_id, subfolder=checkpoint) if checkpoint else PeftModel.from_pretrained(base_model, peft_model_id)
model.config.pad_token_id = tokenizer.pad_token_id
model.eval()

# Example Usage
text = "User: Write a python code for calculating fibonacci sequence.\nAssistant: Here is the code..."
inputs = tokenizer(text, return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model(**inputs)
    reward_score = outputs.logits.squeeze().item()

print(f"[Code] Reward Score: {reward_score:.4f}")
