LLaVA-Gemma Model Card
This model card corresponds to the 2B version of the model with the CLIP-based vision encoder.
Preprint: arxiv.org/abs/2404.01331
Overview
llava-gemma-2b is a large multimodal model (LMM) trained using the LLaVA-v1.5 framework with the 2-billion parameter google/gemma-2b-it model as language backbone.
Uses
The model has been finetuned for multimodal benchmark evaluations, but can also be used as a multimodal chatbot.
Bias, Risks, and Limitations
This model has not been assessed for harm or biases, and should not be used for sensitive applications where it may cause harm.
How to Get Started with the Model
Currently using llava-gemma requires a modified preprocessor.
We are currently working on modifying the LlavaProcessor class to streamline usage (see PR #30030), expect updates soon.
For current usage, see usage.py or the following code block:
import requests
from PIL import Image
from transformers import (
LlavaForConditionalGeneration,
AutoTokenizer,
CLIPImageProcessor
)
from processing_llavagemma import LlavaGemmaProcessor # This is in this repo
checkpoint = "Intel/llava-gemma-2b"
# Load model
model = LlavaForConditionalGeneration.from_pretrained(checkpoint)
processor = LlavaGemmaProcessor(
tokenizer=AutoTokenizer.from_pretrained(checkpoint),
image_processor=CLIPImageProcessor.from_pretrained(checkpoint)
)
# Prepare inputs
# Use gemma chat template
prompt = processor.tokenizer.apply_chat_template(
[{'role': 'user', 'content': "<image>\nWhat's the content of the image?"}],
tokenize=False,
add_generation_prompt=True
)
url = "https://www.ilankelman.org/stopsigns/australia.jpg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = processor(text=prompt, images=image, return_tensors="pt")
# Generate
generate_ids = model.generate(**inputs, max_length=30)
output = processor.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
print(output)
Training Details
The llava-gemma-2b model was trained on 8 Gaudi 2 accelerators.
Training Data
The model was trained using the LLaVA-v1.5 data mixture.
This is listed as follows:
- 558K filtered image-text pairs from LAION/CC/SBU, captioned by BLIP.
- 158K GPT-generated multimodal instruction-following data.
- 450K academic-task-oriented VQA data mixture.
- 40K ShareGPT data.
