Model Details

Demo

Gradio Web Demo

Launch a local web demo by running:

python tinyllava/serve/app.py --model-path bczhou/TinyLLaVA-3.1B --model-name TinyLLaVA-3.1B

CLI Inference

We also support running inference with CLI. To use our model, run:

python -m tinyllava.serve.cli \
    --model-path bczhou/TinyLLaVA-3.1B \
    --image-file "./tinyllava/serve/examples/extreme_ironing.jpg" 

🔧 Quick Start

from tinyllava.model.builder import load_pretrained_model
from tinyllava.mm_utils import get_model_name_from_path
from tinyllava.eval.run_tiny_llava import eval_model

model_path = "bczhou/TinyLLaVA-3.1B"

tokenizer, model, image_processor, context_len = load_pretrained_model(
    model_path=model_path,
    model_base=None,
    model_name=get_model_name_from_path(model_path)
)

🔧 Run Inference

Here's an example of running inference with TinyLLaVA-3.1B

from tinyllava.model.builder import load_pretrained_model
from tinyllava.mm_utils import get_model_name_from_path
from tinyllava.eval.run_tiny_llava import eval_model

model_path = "bczhou/TinyLLaVA-3.1B"
prompt = "What are the things I should be cautious about when I visit here?"
image_file = "https://llava-vl.github.io/static/images/view.jpg"

args = type('Args', (), {
    "model_path": model_path,
    "model_base": None,
    "model_name": get_model_name_from_path(model_path),
    "query": prompt,
    "conv_mode": "phi",
    "image_file": image_file,
    "sep": ",",
    "temperature": 0,
    "top_p": None,
    "num_beams": 1,
    "max_new_tokens": 512
})()

eval_model(args)

Important

We use different conv_mode for different models. Replace the conv_mode in args according to this table: | model | conv_mode | |---------------- |----------- | | TinyLLaVA-3.1B | phi | | TinyLLaVA-2.0B | phi | | TinyLLaVA-1.5B | v1 |

Evaluation

To ensure the reproducibility, we evaluate the models with greedy decoding.

See Evaluation.md

Data Preparation

In our paper, we used two different datasets: the LLaVA dataset and the ShareGPT4V dataset , and compared their differences. In this section, we provide information on data preparation.

Pretraining Images

• LLaVA: The pretraining images of LLaVA is from the 558K subset of the LAION-CC-SBU dataset.
• ShareGPT4V: The pretraining images of ShareGPT4V is a mixture of 558K LAION-CC-SBU subset, SAM dataset, and COCO dataset.

Pretraining Annotations

• LLaVA: The pretraining annotations of LLaVA are here .
• ShareGPT4V: The pretraining annotations of ShareGPT4V are here .

SFT Images & Annotations

The majority of the two SFT datasets are the same, with the exception that the 23K detailed description data in LLaVA-1.5-SFT being replaced with detailed captions randomly sampled from the 100K ShareGPT4V data .

Train

This section we describe the base recipe.

Training script with DeepSpeed ZeRO-3: finetune.sh .

Custom-Finetune

Check out our custom finetune using LoRA here .

- Prompt Template

The model supports multi-image and multi-prompt generation. When using the model, make sure to follow the correct prompt template ( USER: <image>xxx\nASSISTANT: ), where <image> token is a place-holding special token for image embeddings.

Model Inference from pipeline and transformers

- Using pipeline :

Below we used "bczhou/tiny-llava-v1-hf" checkpoint.

from transformers import pipeline
from PIL import Image
import requests
model_id = "bczhou/tiny-llava-v1-hf"
pipe = pipeline("image-to-text", model=model_id)
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/ai2d-demo.jpg"
image = Image.open(requests.get(url, stream=True).raw)
prompt = "USER: <image>\nWhat does the label 15 represent? (1) lava (2) core (3) tunnel (4) ash cloud\nASSISTANT:"
outputs = pipe(image, prompt=prompt, generate_kwargs={"max_new_tokens": 200})
print(outputs[0])
>>> {"generated_text': 'USER:  \nWhat does the label 15 represent? (1) lava (2) core (3) tunnel (4) ash cloud\nASSISTANT: The label 15 represents lava, which is a type of volcanic rock."}

- Using pure transformers :

Below is an example script to run generation in float16 precision on a GPU device:

import requests
from PIL import Image
import torch
from transformers import AutoProcessor, LlavaForConditionalGeneration
model_id = "bczhou/tiny-llava-v1-hf"
prompt = "USER: <image>\nWhat are these?\nASSISTANT:"
image_file = "http://images.cocodataset.org/val2017/000000039769.jpg"
model = LlavaForConditionalGeneration.from_pretrained(
model_id,
torch_dtype=torch.float16,
low_cpu_mem_usage=True,
).to(0)
processor = AutoProcessor.from_pretrained(model_id)
raw_image = Image.open(requests.get(image_file, stream=True).raw)
inputs = processor(prompt, raw_image, return_tensors='pt').to(0, torch.float16)
output = model.generate(**inputs, max_new_tokens=200, do_sample=False)
print(processor.decode(output[0][2:], skip_special_tokens=True))
