Model Card for LLaVA-NDiNO_pt_short_long

Model description

LLaVA-NDiNO is a family of Large Vision Language Models (LVLMs) that have been trained for the Italian language.

The model was trained by instruction-tuning LLaVA-NDiNO_pt_short on an Italian machine-translated version of LLaVA Conversation 58k.

If you are interested in more details regarding the training procedure, you can find the code we used at the following link:

Example Usage

import torch
import requests

from PIL import Image
from transformers import LlavaNextProcessor, LlavaNextForConditionalGeneration, set_seed

model_name = "swap-uniba/LLaVA-NDiNO_pt_short_long"

processor = LlavaNextProcessor.from_pretrained(model_name)
model = LlavaNextForConditionalGeneration.from_pretrained(model_name, torch_dtype=torch.bfloat16, low_cpu_mem_usage=True, device_map="auto") 

url = "https://www.barnorama.com/wp-content/uploads/2016/12/03-Confusing-Pictures.jpg"
image = Image.open(requests.get(url, stream=True).raw)

chat_template = "{% set loop_messages = messages %}{% for message in loop_messages %}{% set content = '<|start_header_id|>' + message['role'] + '<|end_header_id|>\n\n'+ message['content'] | trim + '<|eot_id|>' %}{% if loop.index0 == 0 %}{% set content = bos_token + content %}{% endif %}{{ content }}{% endfor %}{% if add_generation_prompt %}{{ '<|start_header_id|>assistant<|end_header_id|>\n\n' }}{% endif %}"

conversation = [
    {
        "role": "user",
        "content": "<image>\nCosa c'è di strano in questa immagine?"
    },
]

prompt = processor.apply_chat_template(conversation, chat_template, add_generation_prompt=True)
inputs = processor(prompt, image, return_tensors="pt")

set_seed(42)
output = model.generate(**inputs, max_new_tokens=4096)

print(processor.decode(output[0][inputs.input_ids.shape[1]:]))
