# llama-3.1-8B-vision-378 |
|
|
|
Projection module trained to add vision capabilties to Llama 3 using SigLIP, then applied to Llama-3.1-8B-Instruct. Built by [@yeswondwerr](https://x.com/yeswondwerr) and [@qtnx_](https://x.com/qtnx_). |
|
|
|
## Usage |
|
|
|
```python |
|
import torch |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
from PIL import Image |
|
import requests |
|
from io import BytesIO |
|
|
|
url = "https://huggingface.co/qresearch/llama-3-vision-alpha-hf/resolve/main/assets/demo-2.jpg" |
|
response = requests.get(url) |
|
image = Image.open(BytesIO(response.content)) |
|
|
|
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
"qresearch/llama-3.1-8B-vision-378", |
|
trust_remote_code=True, |
|
torch_dtype=torch.float16, |
|
).to("cuda") |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("qresearch/llama-3.1-8B-vision-378", use_fast=True,) |
|
|
|
print( |
|
model.answer_question( |
|
image, "Briefly describe the image", tokenizer, max_new_tokens=128, do_sample=True, temperature=0.3 |
|
), |
|
) |
|
``` |
|
|
|
## 4-bit quantization |
|
|
|
```python |
|
import torch |
|
from PIL import Image |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
from transformers import BitsAndBytesConfig |
|
import requests |
|
from io import BytesIO |
|
|
|
|
|
url = "https://huggingface.co/qresearch/llama-3-vision-alpha-hf/resolve/main/assets/demo-2.jpg" |
|
response = requests.get(url) |
|
image = Image.open(BytesIO(response.content)) |
|
|
|
bnb_cfg = BitsAndBytesConfig( |
|
load_in_4bit=True, |
|
bnb_4bit_compute_dtype=torch.float16, |
|
llm_int8_skip_modules=["mm_projector", "vision_model"], |
|
) |
|
|
|
model = AutoModelForCausalLM.from_pretrained( |

|

|
|
|
tokenizer = AutoTokenizer.from_pretrained( |
|
"qresearch/llama-3.1-8B-vision-378", |
|
use_fast=True, |
|
) |
|
|
|
print( |
|
model.answer_question( |
|
image, "Briefly describe the image", tokenizer, max_new_tokens=128, do_sample=True, temperature=0.3 |
