# LLaVA-Gemma Model Card |
|
|
|
_This model card corresponds to the 2B version of the model with the CLIP-based vision encoder._ |
|
|
|
## Overview |
|
|
|
`llava-gemma-2b` is a large multimodal model (LMM) trained using the [LLaVA-v1.5 framework](https://arxiv.org/abs/2310.03744) 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](/processing_llavagemma.py). |
|
|
|
For example usage, see [`usage.py`](/usage.py) or the following code block: |
|
|
|
|
|
```python |
|
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': "What's the content of the image?<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") |
|
inputs = {k: v.to('cuda') for k, v in inputs.items()} |
|
|
|
# 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. |
|
|
|
