This llama model was trained 2x faster with Unsloth and Huggingface's TRL library.

model_id = "llm-jp/llm-jp-3-13b" new_model_id = "llm-jp-3-13b-it" #Fine-Tuningしたモデルにつけたい名前、it: Instruction Tuning

FastLanguageModel インスタンスを作成

model, tokenizer = FastLanguageModel.from_pretrained( model_name=model_id, dtype=dtype, load_in_4bit=load_in_4bit, trust_remote_code=True, )

SFT用のモデルを用意

model = FastLanguageModel.get_peft_model( model, r = 32, target_modules = ["q_proj", "k_proj", "v_proj", "o_proj", "gate_proj", "up_proj", "down_proj",], lora_alpha = 32, lora_dropout = 0.05, bias = "none", use_gradient_checkpointing = "unsloth", random_state = 3407, use_rslora = False, loftq_config = None, max_seq_length = max_seq_length, )

学習時のプロンプトフォーマットの定義

prompt = """### 指示 {}

回答

{}"""

""" formatting_prompts_func: 各データをプロンプトに合わせた形式に合わせる """ EOS_TOKEN = tokenizer.eos_token # トークナイザーのEOSトークン（文末トークン） def formatting_prompts_func(examples): input = examples["text"] # 入力データ output = examples["output"] # 出力データ text = prompt.format(input, output) + EOS_TOKEN # プロンプトの作成 return { "formatted_text" : text, } # 新しいフィールド "formatted_text" を返す pass

# 各データにフォーマットを適用

学習したモデルを用いてタスクを実行

from tqdm import tqdm

推論するためにモデルのモードを変更

FastLanguageModel.for_inference(model)

results = [] for dt in tqdm(datasets): input = dt["input"]

prompt = f"""### 指示\n{input}\n### 回答\n"""

inputs = tokenizer([prompt], return_tensors = "pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens = 512, use_cache = True, do_sample=False, repetition_penalty=1.2) prediction = tokenizer.decode(outputs[0], skip_special_tokens=True).split('\n### 回答')[-1]

results.append({"task_id": dt["task_id"], "input": input, "output": prediction})

jsonlで保存

with open(f"{new_model_id}_output.jsonl", 'w', encoding='utf-8') as f: for result in results: json.dump(result, f, ensure_ascii=False) f.write('\n')

LoRAアダプタだけ保存

model.push_to_hub_merged( new_model_id+"_lora", tokenizer=tokenizer, save_method="lora", token="token", private=True )
