## Model |
|
|
|
llava-llama-3-8b-v1_1-hf is a LLaVA model fine-tuned from [meta-llama/Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) and [CLIP-ViT-Large-patch14-336](https://huggingface.co/openai/clip-vit-large-patch14-336) with [ShareGPT4V-PT](https://huggingface.co/datasets/Lin-Chen/ShareGPT4V) and [InternVL-SFT](https://github.com/OpenGVLab/InternVL/tree/main/internvl_chat#prepare-training-datasets) by [XTuner](https://github.com/InternLM/xtuner). |

## QuickStart |
|
|
|
|
|
### Chat by `pipeline` |
|
|
|
|
|
```python |
|
from transformers import pipeline |
|
from PIL import Image |
|
import requests |
|
|
|
model_id = "xtuner/llava-llama-3-8b-v1_1-transformers" |
|
pipe = pipeline("image-to-text", model=model_id, device=0) |
|
url = "http://images.cocodataset.org/val2017/000000039769.jpg" |
|
|
|
image = Image.open(requests.get(url, stream=True).raw) |
|
prompt = ("<|start_header_id|>user<|end_header_id|>\n\n<image>\nWhat are these?<|eot_id|>" |
|
"<|start_header_id|>assistant<|end_header_id|>\n\n") |
|
outputs = pipe(image, prompt=prompt, generate_kwargs={"max_new_tokens": 200}) |
|
print(outputs) |
|
>>> [{'generated_text': 'user\n\n\nWhat are these?assistant\n\nThese are two cats, one brown and one gray, lying on a pink blanket. sleep. brown and gray cat sleeping on a pink blanket.'}] |
|
``` |
|
|
|
### Chat by pure `transformers` |
|
|
|
```python |
|
import requests |
|
from PIL import Image |
|
|
|
import torch |
|
from transformers import AutoProcessor, LlavaForConditionalGeneration |
|
|
|
model_id = "xtuner/llava-llama-3-8b-v1_1-transformers" |
|
|
|
prompt = ("<|start_header_id|>user<|end_header_id|>\n\n<image>\nWhat are these?<|eot_id|>" |
|
"<|start_header_id|>assistant<|end_header_id|>\n\n") |
|
image_file = "http://images.cocodataset.org/val2017/000000039769.jpg" |
|
|
|
model = LlavaForConditionalGeneration.from_pretrained( |
|
model_id, |
|
torch_dtype=torch.float16, |
|
low_cpu_mem_usage=True, |
|
).to(0) |
|
|
|
processor = AutoProcessor.from_pretrained(model_id) |
|
|
|
|
|
raw_image = Image.open(requests.get(image_file, stream=True).raw) |
|
inputs = processor(prompt, raw_image, return_tensors='pt').to(0, torch.float16) |
|
|
|
output = model.generate(**inputs, max_new_tokens=200, do_sample=False) |
|
print(processor.decode(output[0][2:], skip_special_tokens=True)) |
|
>>> These are two cats, one brown and one gray, lying on a pink blanket. sleep. brown and gray cat sleeping on a pink blanket. |
|
``` |
|
|
|
|
|
