# LLaVA-Next-Inst-It-Vicuna-7B
[**Homepage**](https://inst-it.github.io/) | [**Code**](https://github.com/inst-it/inst-it) | [**Paper**](https://huggingface.co/papers/2412.03565) | [**arXiv**](https://arxiv.org/abs/2412.03565)

LLaVA-Next-Inst-It-Vicuna-7B is a multimodal model that excels at instance-level understanding, 
which is introduced in the paper [Inst-IT: Boosting Multimodal Instance Understanding via Explicit Visual Prompt Instruction Tuning](https://huggingface.co/papers/2412.03565)

* **Architecture**: clip-vit-large-patch14-336 + Vicuna-7B
* **Initialized Model**: LLaVA-NeXT
* **Data**: LLaVA-NeXT-Data / Inst-IT-Dataset
* **Precision**: bfloat16


## Quick Start
**Install**

Our code is based on LLaVA-NeXT, before running, please install the LLaVA-NeXT to prepare the environment:
```shell
pip install git+https://github.com/LLaVA-VL/LLaVA-NeXT.git
```
**Load Model**
```python
from llava.model.builder import load_pretrained_model
from llava.constants import (
    DEFAULT_IM_END_TOKEN,
    DEFAULT_IM_START_TOKEN,
    DEFAULT_IMAGE_TOKEN,
    IGNORE_INDEX,
    IMAGE_TOKEN_INDEX,
)
from llava.mm_utils import (
    KeywordsStoppingCriteria,
    get_model_name_from_path,
    tokenizer_image_token,
    process_images
)
from llava.conversation import SeparatorStyle, conv_templates

overwrite_config = {}
overwrite_config["mm_spatial_pool_stride"] = 2
overwrite_config["mm_spatial_pool_mode"] = 'bilinear'
overwrite_config["mm_pooling_position"] = 'after'
overwrite_config["mm_newline_position"] = 'no_token'

model_path = "Inst-IT/LLaVA-Next-Inst-It-Vicuna-7B"
model_name = get_model_name_from_path(model_path)

tokenizer, model, image_processor, max_length = load_pretrained_model(
            model_path=model_path, 
            model_base=None, 
            model_name=model_name,
            device_map="auto", 
            torch_dtype='bfloat16', 
            overwrite_config=overwrite_config,
            attn_implementation='sdpa')
```
**Image Inference**

<details>
<summary>Inference without SoMs</summary>

Our model can perform inference on images without [Set-of-Marks](https://arxiv.org/abs/2310.11441) visual prompts, in this case, it can be used in the same way as its base mode [LLaVA-NeXT](https://github.com/LLaVA-VL/LLaVA-NeXT).

```python
import torch
import requests
from PIL import Image

img_url = "https://github.com/inst-it/inst-it/blob/main/assets/demo/image.jpg?raw=true"
image = Image.open(requests.get(img_url, stream=True).raw)
image_tensor = process_images([image], image_processor, model.config).bfloat16()
image_sizes = [image.size]

question = "Describe this image."
question = DEFAULT_IMAGE_TOKEN + "\n" + question

conv_template = 'vicuna_v1'
conv = conv_templates[conv_template].copy()
conv.append_message(conv.roles[0], question)
conv.append_message(conv.roles[1], None)
prompt = conv.get_prompt()

input_ids = tokenizer_image_token(prompt, tokenizer, IMAGE_TOKEN_INDEX, return_tensors="pt").unsqueeze(0).cuda()

pad_token_ids = tokenizer.pad_token_id if tokenizer.pad_token_id is not None else tokenizer.eos_token_id
attention_masks = input_ids.ne(pad_token_ids).long().cuda()

stop_str = conv.sep if conv.sep_style != SeparatorStyle.TWO else conv.sep2
keywords = [stop_str]
stopping_criteria = KeywordsStoppingCriteria(keywords, tokenizer, input_ids)

with torch.inference_mode():
    output_ids = model.generate(
        inputs=input_ids,
        images=image_tensor,
        attention_mask=attention_masks,
        modalities="image",
        image_sizes=image_sizes,
        use_cache=True,
        stopping_criteria=[stopping_criteria],
        max_new_tokens=4096
    )

pred = tokenizer.batch_decode(output_ids, skip_special_tokens=True)[0].strip()
print(pred)
```
</details>

<details>
<summary>Inference with SoMs</summary>

Our model performs more fine-grained understanding when [Set-of-Marks](https://arxiv.org/abs/2310.11441) visual prompts are provided. 
You can refer to the instances that you are interested in using their IDs.
Compared to the previous inference code, the following code has no modifications except for the input image, which is visual prompted with Set-of-Marks. 
Refer to [this link](https://github.com/microsoft/SoM) to learn how to generate SoMs for an image.

```python
import torch
import requests
from PIL import Image

img_url = "https://github.com/inst-it/inst-it/blob/main/assets/demo/image_som.jpg?raw=true"
image = Image.open(requests.get(img_url, stream=True).raw)
image_tensor = process_images([image], image_processor, model.config).bfloat16()
image_sizes = [image.size]

# You can use [id] to refer to the instances that you are interested in
question = "Describe [8] in detail."
question = DEFAULT_IMAGE_TOKEN + "\n" + question

conv_template = 'vicuna_v1'
conv = conv_templates[conv_template].copy()
conv.append_message(conv.roles[0], question)
conv.append_message(conv.roles[1], None)
prompt = conv.get_prompt()

input_ids = tokenizer_image_token(prompt, tokenizer, IMAGE_TOKEN_INDEX, return_tensors="pt").unsqueeze(0).cuda()

pad_token_ids = tokenizer.pad_token_id if tokenizer.pad_token_id is not None else tokenizer.eos_token_id
attention_masks = input_ids.ne(pad_token_ids).long().cuda()

stop_str = conv.sep if conv.sep_style != SeparatorStyle.TWO else conv.sep2
keywords = [stop_str]
stopping_criteria = KeywordsStoppingCriteria(keywords, tokenizer, input_ids)

with torch.inference_mode():
    output_ids = model.generate(
        inputs=input_ids,
        images=image_tensor,
        attention_mask=attention_masks,
        modalities="image",
        image_sizes=image_sizes,
        use_cache=True,
        stopping_criteria=[stopping_criteria],
        max_new_tokens=4096
    )

pred = tokenizer.batch_decode(output_ids, skip_special_tokens=True)[0].strip()
print(pred)
```
</details>

**Video Inference**

For the video, we organize each frame into a list. You can use the format \<t\> to refer to a specific timestamp (e.g. <1>).

<details>
<summary>Inference without SoMs</summary>

Our model can perform inference on videos without [Set-of-Marks](https://arxiv.org/abs/2310.11441) visual prompts, in this case, it can be used in the same way as its base mode [LLaVA-NeXT](https://github.com/LLaVA-VL/LLaVA-NeXT).
