ベースとなるモデルと学習したLoRAのアダプタ。

model_idの値は適宜変更

model_id = "llm-jp/llm-jp-3-13b" adapter_id = "tarosaii/llm-jp-3-13b-finetune5"

QLoRAのconfig

bnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_quant_type="nf4", bnb_4bit_compute_dtype=torch.bfloat16, )

Load model

model = AutoModelForCausalLM.from_pretrained( model_id, quantization_config=bnb_config, device_map="auto", token = HF_TOKEN )

Load tokenizer

tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True, token = HF_TOKEN)

元のモデルにLoRAのアダプタを統合。

model = PeftModel.from_pretrained(model, adapter_id, token = HF_TOKEN)

タスクとなるデータセットの読み込み。

事前にデータセットをアップロード

datasets = [] with open("./elyza-tasks-100-TV_0.jsonl", "r") as f: item = "" for line in f: line = line.strip() item += line if item.endswith("}"): datasets.append(json.loads(item)) item = ""

モデルを用いてタスクの推論

results = [] for data in tqdm(datasets):

input = data["input"] prompt = f"""### 指示 {input}

回答

"""

トークナイズ（input_idsのみ取得）

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

出力生成

outputs = model.generate( input_ids=input_ids, max_new_tokens=512, do_sample=False, repetition_penalty=1.2, )

出力をデコード

output_text = tokenizer.decode( outputs[0][input_ids.size(1):], skip_special_tokens=True )

results.append({"task_id": data["task_id"], "input": input, "output": output_text})

結果をjsonlで保存。

import re jsonl_id = re.sub(".*/", "", adapter_id) with open(f"./{jsonl_id}-outputs.jsonl", 'w', encoding='utf-8') as f: for result in results: json.dump(result, f, ensure_ascii=False) # ensure_ascii=False for handling non-ASCII characters f.write('\n')
