模型:
Salesforce/instructblip-flan-t5-xl
使用 Flan-T5-xl 作为语言模型的 InstructBLIP 模型。InstructBLIP 模型是由 Dai 等人在 InstructBLIP: Towards General-purpose Vision-Language Models with Instruction Tuning 论文中介绍的。
声明:发布 InstructBLIP 的团队未为该模型编写模型卡片,因此该模型卡片是由 Hugging Face 团队编写的。
InstructBLIP 是 BLIP-2 的视觉指导版本。详情请参阅论文。
 
  使用方式如下:
from transformers import InstructBlipProcessor, InstructBlipForConditionalGeneration
import torch
from PIL import Image
import requests
model = InstructBlipForConditionalGeneration.from_pretrained("Salesforce/instructblip-flan-t5-xl")
processor = InstructBlipProcessor.from_pretrained("Salesforce/instructblip-flan-t5-xl")
device = "cuda" if torch.cuda.is_available() else "cpu"
model.to(device)
url = "https://raw.githubusercontent.com/salesforce/LAVIS/main/docs/_static/Confusing-Pictures.jpg"
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
prompt = "What is unusual about this image?"
inputs = processor(images=image, text=prompt, return_tensors="pt").to(device)
outputs = model.generate(
        **inputs,
        do_sample=False,
        num_beams=5,
        max_length=256,
        min_length=1,
        top_p=0.9,
        repetition_penalty=1.5,
        length_penalty=1.0,
        temperature=1,
)
generated_text = processor.batch_decode(outputs, skip_special_tokens=True)[0].strip()
print(generated_text)
