# 생성을 위한 유틸리티 [[utilities-for-generation]]
이 페이지는 [`~generation.GenerationMixin.generate`]에서 사용되는 모든 유틸리티 함수들을 나열합니다.
## 출력을 생성하기 (Generate Outputs) [[generate-outputs]]
[`~generation.GenerationMixin.generate`]의 출력은 [`~utils.ModelOutput`]의 하위 클래스의 인스턴스입니다. 이 출력은 [`~generation.GenerationMixin.generate`]에서 반환되는 모든 정보를 포함하는 데이터 구조체이며, 튜플 또는 딕셔너리로도 사용할 수 있습니다.
다음은 예시입니다:
```python
from transformers import GPT2Tokenizer, GPT2LMHeadModel
tokenizer = GPT2Tokenizer.from_pretrained("openai-community/gpt2")
model = GPT2LMHeadModel.from_pretrained("openai-community/gpt2")
inputs = tokenizer("Hello, my dog is cute and ", return_tensors="pt")
generation_output = model.generate(**inputs, return_dict_in_generate=True, output_scores=True)
```
`generation_output` 객체는 [`~generation.GenerateDecoderOnlyOutput`]입니다. 아래 문서에서 확인할 수 있듯이, 이 클래스는 다음과 같은 속성을 가지고 있습니다:
- `sequences`: 생성된 토큰 시퀀스
- `scores` (옵션): 각 생성 단계에서 언어 모델링 헤드의 예측 점수
- `hidden_states` (옵션): 각 생성 단계에서 모델의 은닉 상태
- `attentions` (옵션): 각 생성 단계에서 모델의 어텐션 가중치
`output_scores=True`를 전달했기 때문에 `scores`는 포함되어 있지만, `output_hidden_states=True` 또는 `output_attentions=True`를 전달하지 않았으므로 `hidden_states``attentions`는 포함되지 않았습니다.
각 속성은 일반적으로 접근할 수 있으며, 모델이 해당 속성을 반환하지 않았다면 `None`이 반환됩니다. 예를 들어, `generation_output.scores`는 언어 모델링 헤드에서 생성된 모든 예측 점수를 포함하고 있으며, `generation_output.attentions``None`입니다.
`generation_output` 객체를 튜플로 사용할 경우, `None` 값이 아닌 속성만 포함됩니다. 예를 들어, `loss``logits`라는 두 요소가 포함된 경우:
```python
generation_output[:2]
```
위 코드는 `(generation_output.sequences, generation_output.scores)` 튜플을 반환합니다.
`generation_output` 객체를 딕셔너리로 사용할 경우, `None` 값이 아닌 속성만 포함됩니다. 예를 들어, `sequences``scores`라는 두 개의 키를 가질 수 있습니다.
여기서는 모든 출력 유형을 문서화합니다.
