Heron GIT Llama 2 Fast 7B

Model Details

Heron GIT Llama 2 7B is a vision-language model that can converse about input images.<br> This model was trained using the heron library. Please refer to the code for details.

Usage

Follow the installation guide.

import requests
from PIL import Image

import torch
from transformers import AutoProcessor
from heron.models.git_llm.git_llama import GitLlamaConfig, GitLlamaForCausalLM

device_id = 0

# prepare a pretrained model
model = GitLlamaForCausalLM.from_pretrained(
    'turing-motors/heron-chat-git-Llama-2-7b-v0', torch_dtype=torch.float16
)
model.eval()
model.to(f"cuda:{device_id}")

# prepare a processor
processor = AutoProcessor.from_pretrained('turing-motors/heron-chat-git-Llama-2-7b-v0')

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

text = f"##human: What is this picture?\n##gpt: "

# do preprocessing
inputs = processor(
    text,
    image,
    return_tensors="pt",
    truncation=True,
)
inputs = {k: v.to(f"cuda:{device_id}") for k, v in inputs.items()}

# set eos token
eos_token_id_list = [
    processor.tokenizer.pad_token_id,
    processor.tokenizer.eos_token_id,
]

# do inference
with torch.no_grad():
    out = model.generate(**inputs, max_length=256, do_sample=False, temperature=0., eos_token_id=eos_token_id_list)

# print result
print(processor.tokenizer.batch_decode(out)[0])

Model Details

• Developed by: Turing Inc.
• Adaptor type: GIT
• Lamguage Model: meta-llama/Llama-2-7b-chat-hf
• Language(s): English

Training

This model was initially trained with the Adaptor using Coco Captions in M3IT. In the second phase, it was fine-tuned with M3IT. Finally, it was trained by instruction tuning with LLaVA-Instruct-150K.

Training Dataset

• LLaVA-Instruct-150K
• M3IT

Use and Limitations

Intended Use

This model is intended for use in chat-like applications and for research purposes.

Limitations

The model may produce inaccurate or false information, and its accuracy is not guaranteed. It is still in the research and development stage.
