# 소형 비전 언어 모델(SmolVLM)[[smolvlm]]

## 개요[[overview]]
[SmolVLM2](https://huggingface.co/papers/2504.05299) ([블로그 글](https://huggingface.co/blog/smolvlm2)) 은 Idefics3 모델을 개선한 버전으로, 두 가지 주요 차이점이 있습니다:

- 텍스트 모델로 SmolLM2를 사용합니다.
- 한 장의 이미지뿐 아니라 여러 장의 이미지와 비디오 입력도 지원합니다.

## 사용 팁[[usage-tips]]

입력된 이미지는 설정에 따라 원본 해상도를 유지하거나 크기를 조절할 수 있습니다. 이때 이미지 크기 조절 여부와 방식은 `do_resize`와 `size` 파라미터로 결정됩니다.

비디오의 경우에는 업샘플링을 하면 안 됩니다.

만약 `do_resize`가 `True`일 경우, 모델은 기본적으로 이미지의 가장 긴 변을 4*512 픽셀이 되도록 크기를 조절합니다.
이 기본 동작은 `size` 파라미터에 딕셔너리를 전달하여 원하는 값으로 직접 설정할 수 있습니다. 예를 들어, 기본값은 `{"longest_edge": 4 * 512}` 이여도 사용자 필요에 따라 다른 값으로 변경할 수 있습니다.

다음은 리사이징을 제어하고 사용자 정의 크기로 변경하는 방법입니다:
```python
image_processor = SmolVLMImageProcessor(do_resize=True, size={"longest_edge": 2 * 512}, max_image_size=512)
```

또한, `max_image_size` 매개변수는 이미지를 분할하는 정사각형 패치의 크기를 제어합니다. 이 값은 기본적으로 512로 설정되어 있으며 필요에 따라 조정 가능합니다. 이미지 처리기는 리사이징을 마친 후, `max_image_size` 값을 기준으로 이미지를 여러 개의 정사각형 패치로 분할합니다.

## 사용 예시[[usage-example]]

### 단일 미디어 추론[[single-media-inference]]

이 모델은 이미지와 비디오를 모두 입력으로 받을 수 있지만, 한 번에 사용할 수 있는 미디어는 반드시 하나의 종류여야 합니다. 관련 예시 코드는 다음과 같습니다.

```python
import torch
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("HuggingFaceTB/SmolVLM2-256M-Video-Instruct")
model = AutoModelForImageTextToText.from_pretrained(
    "HuggingFaceTB/SmolVLM2-256M-Video-Instruct",
    dtype=torch.bfloat16,
    device_map="auto"
)

conversation = [
    {
        "role": "user",
        "content":[
            {"type": "image", "url": "http://images.cocodataset.org/val2017/000000039769.jpg"},
            {"type": "text", "text": "이 이미지에 대해 설명해주세요."}
        ]
    }
]

inputs = processor.apply_chat_template(
    conversation,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device, dtype=torch.bfloat16)

output_ids = model.generate(**inputs, max_new_tokens=128)
generated_texts = processor.batch_decode(output_ids, skip_special_tokens=True)
print(generated_texts)

# Video

    {
        "role": "user",
        "content": [
            {"type": "video", "path": "/path/to/video.mp4"},
            {"type": "text", "text": "이 비디오에 대해 자세히 설명해주세요."}
        ]
    },
]

inputs = processor.apply_chat_template(
    conversation,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device, dtype=torch.bfloat16)

generated_ids = model.generate(**inputs, do_sample=False, max_new_tokens=100)

model = AutoModelForImageTextToText.from_pretrained(
    "HuggingFaceTB/SmolVLM2-256M-Video-Instruct",
    dtype=torch.bfloat16,
    device_map="auto"
)

# 첫 번째 이미지에 대한 구성
conversation1 = [
    {
        "role": "user",
        "content": [
            {"type": "image", "path": "/path/to/image.jpg"},
            {"type": "text", "text": "이 이미지에 대해 설명해주세요."}
        ]
    }
]

# 두 장의 이미지를 포함한 구성
conversation2 = [
    {
        "role": "user",
        "content": [
            {"type": "image", "path": "/path/to/image.jpg"},
            {"type": "image", "path": "/path/to/image.jpg"},
            {"type": "text", "text": "그림에 무엇이 적혀있나요?"}
        ]
    }
]

# 텍스트만 포함하고 있는 구성
conversation3 = [
    {"role": "user","content": "당신은 누구인가요?"}
]

conversations = [conversation1, conversation2, conversation3]
inputs = processor.apply_chat_template(
    conversation,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device, dtype=torch.bfloat16)

generated_ids = model.generate(**inputs, do_sample=False, max_new_tokens=100)
generated_texts = processor.batch_decode(generated_ids, skip_special_tokens=True)
print(generated_texts[0])
```

```

[Source](https://github.com/huggingface/transformers/blob/v5.15.0/src/transformers/models/smolvlm/modeling_smolvlm.py#L563)

**Parameters:**

input_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) : Indices of input sequence tokens in the vocabulary. Padding will be ignored by default.  Indices can be obtained using [AutoTokenizer](/docs/transformers/v5.15.0/ko/model_doc/auto#transformers.AutoTokenizer). See [PreTrainedTokenizer.encode()](/docs/transformers/v5.15.0/ko/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.encode) and [PreTrainedTokenizer.__call__()](/docs/transformers/v5.15.0/ko/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.__call__) for details.  [What are input IDs?](../glossary#input-ids)

attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*) : Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:  - 1 for tokens that are **not masked**, - 0 for tokens that are **masked**.  [What are attention masks?](../glossary#attention-mask)

position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) : Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0, config.n_positions - 1]`.  [What are position IDs?](../glossary#position-ids)

past_key_values (`~cache_utils.Cache`, *optional*) : Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values` returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.  Only [Cache](/docs/transformers/v5.15.0/ko/internal/generation_utils#transformers.Cache) instance is allowed as input, see our [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache). If no `past_key_values` are passed, [DynamicCache](/docs/transformers/v5.15.0/ko/internal/generation_utils#transformers.DynamicCache) will be initialized by default.  The model will output the same cache format that is fed as input.  If `past_key_values` are used, the user is expected to input only unprocessed `input_ids` (those that don't have their past key value states given to this model) of shape `(batch_size, unprocessed_length)` instead of all `input_ids` of shape `(batch_size, sequence_length)`.

inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) : Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This is useful if you want more control over how to convert `input_ids` indices into associated vectors than the model's internal embedding lookup matrix.

pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)`, *optional*) : The tensors corresponding to the input images. Pixel values can be obtained using [SmolVLMImageProcessor](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMImageProcessor). See `SmolVLMImageProcessor.__call__()` for details ([SmolVLMProcessor](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMProcessor) uses [SmolVLMImageProcessor](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMImageProcessor) for processing images).

pixel_attention_mask (`torch.Tensor` of shape `(batch_size, image_size, image_size)`, *optional*) : Mask to avoid performing attention on padding pixel indices.

image_hidden_states (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)`) : The hidden states of the image encoder after modality projection.

use_cache (`bool`, *optional*) : If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see `past_key_values`).

**Returns:** `SmolVLMBaseModelOutputWithPast` or `tuple(torch.FloatTensor)`

A `SmolVLMBaseModelOutputWithPast` or a tuple of
`torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various
elements depending on the configuration ([SmolVLMConfig](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMConfig)) and inputs.

Inputs fed to the model can have an arbitrary number of images. To account for this, pixel_values fed to
the model have image padding -> (batch_size, max_num_images, 3, max_heights, max_widths) where
max_num_images is the maximum number of images among the batch_size samples in the batch.
Padding images are not needed beyond padding the pixel_values at the entrance of the model.
For efficiency, we only pass through the vision_model's forward the real images by
discarding the padding images i.e. pixel_values of size (image_batch_size, 3, height, width) where
image_batch_size would be 7 when num_images_per_sample=[1, 3, 1, 2] and max_num_images would be 3.

- **last_hidden_state** (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`) -- Sequence of hidden-states at the output of the last layer of the model.
  If `past_key_values` is used only the last hidden-state of the sequences of shape `(batch_size, 1,
  hidden_size)` is output.
- **past_key_values** (`~cache_utils.Cache`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`) -- It is a [Cache](/docs/transformers/v5.15.0/ko/internal/generation_utils#transformers.Cache) instance. For more details, see our [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache).

  Contains pre-computed hidden-states (key and values in the self-attention blocks and optionally if
  `config.is_encoder_decoder=True` in the cross-attention blocks) that can be used (see `past_key_values`
  input) to speed up sequential decoding.
- **hidden_states** (`tuple[torch.FloatTensor]`, *optional*, returned when `output_hidden_states=True` is passed or when `config.output_hidden_states=True`) -- Tuple of `torch.FloatTensor` (one for the output of the embeddings, if the model has an embedding layer, +
  one for the output of each layer) of shape `(batch_size, sequence_length, hidden_size)`.

  Hidden-states of the model at the output of each layer plus the optional initial embedding outputs.
- **attentions** (`tuple[torch.FloatTensor]`, *optional*, returned when `output_attentions=True` is passed or when `config.output_attentions=True`) -- Tuple of `torch.FloatTensor` (one for each layer) of shape `(batch_size, num_heads, sequence_length,
  sequence_length)`.

  Attentions weights after the attention softmax, used to compute the weighted average in the self-attention
  heads.
- **image_hidden_states** (`tuple(torch.FloatTensor)`, *optional*) -- Tuple of `torch.FloatTensor` (one for the output of the image embeddings, `(batch_size, num_images,
  sequence_length, hidden_size)`.
  image_hidden_states of the model produced by the vision encoder

position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) : Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0, config.n_positions - 1]`.  [What are position IDs?](../glossary#position-ids)

past_key_values (`~cache_utils.Cache`, *optional*) : Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values` returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.  Only [Cache](/docs/transformers/v5.15.0/ko/internal/generation_utils#transformers.Cache) instance is allowed as input, see our [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache). If no `past_key_values` are passed, [DynamicCache](/docs/transformers/v5.15.0/ko/internal/generation_utils#transformers.DynamicCache) will be initialized by default.  The model will output the same cache format that is fed as input.  If `past_key_values` are used, the user is expected to input only unprocessed `input_ids` (those that don't have their past key value states given to this model) of shape `(batch_size, unprocessed_length)` instead of all `input_ids` of shape `(batch_size, sequence_length)`.

inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*) : Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This is useful if you want more control over how to convert `input_ids` indices into associated vectors than the model's internal embedding lookup matrix.

pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)`, *optional*) : The tensors corresponding to the input images. Pixel values can be obtained using [SmolVLMImageProcessor](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMImageProcessor). See `SmolVLMImageProcessor.__call__()` for details ([SmolVLMProcessor](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMProcessor) uses [SmolVLMImageProcessor](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMImageProcessor) for processing images).

pixel_attention_mask (`torch.Tensor` of shape `(batch_size, image_size, image_size)`, *optional*) : Mask to avoid performing attention on padding pixel indices.

image_hidden_states (`torch.FloatTensor` of shape `(batch_size, num_channels, image_size, image_size)`) : The hidden states of the image encoder after modality projection.

labels (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*) : Labels for computing the masked language modeling loss. Indices should either be in `[0, ..., config.vocab_size]` or `model.image_token_id`. Tokens with indices set to `model.image_token_id` are ignored (masked), the loss is only computed for the tokens with labels in `[0, ..., config.vocab_size]`.

use_cache (`bool`, *optional*) : If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see `past_key_values`).

logits_to_keep (`Union[int, torch.Tensor]`, *optional*, defaults to `0`) : If an `int`, compute logits for the last `logits_to_keep` tokens. If `0`, calculate logits for all `input_ids` (special case). Only last token logits are needed for generation, and calculating them only for that token can save memory, which becomes pretty significant for long sequences or large vocabulary size. If a `torch.Tensor`, must be 1D corresponding to the indices to keep in the sequence length dimension. This is useful when using packed tensor format (single dimension for batch and sequence length).

**Returns:** `SmolVLMCausalLMOutputWithPast` or `tuple(torch.FloatTensor)`

A `SmolVLMCausalLMOutputWithPast` or a tuple of
`torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various
elements depending on the configuration ([SmolVLMConfig](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMConfig)) and inputs.

The [SmolVLMForConditionalGeneration](/docs/transformers/v5.15.0/ko/model_doc/smolvlm#transformers.SmolVLMForConditionalGeneration) forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module`
instance afterwards instead of this since the former takes care of running the pre and post processing steps while
the latter silently ignores them.

- **loss** (`torch.FloatTensor` of shape `(1,)`, *optional*, returned when `labels` is provided) -- Language modeling loss (for next-token prediction).
- **logits** (`torch.FloatTensor` of shape `(batch_size, sequence_length, config.vocab_size)`) -- Prediction scores of the language modeling head (scores for each vocabulary token before SoftMax).

For more details, see our [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache).

  Contains pre-computed hidden-states (key and values in the self-attention blocks) that can be used (see
  `past_key_values` input) to speed up sequential decoding.

  one for the output of each layer) of shape `(batch_size, sequence_length, hidden_size)`.

- **attentions** (`tuple[torch.FloatTensor]`, *optional*, returned when `output_attentions=True` is passed or when `config.output_attentions=True`) -- Tuple of `torch.FloatTensor` (one for each layer) of shape `(batch_size, num_heads, sequence_length,
  sequence_length)`.

  Attentions weights after the attention softmax, used to compute the weighted average in the self-attention
  heads.
- **image_hidden_states** (`tuple(torch.FloatTensor)`, *optional*) -- Tuple of `torch.FloatTensor` (one for the output of the image embeddings, `(batch_size, num_images,
  sequence_length, hidden_size)`.
