Florence-2-large-ft trained on task MORE_DETAILED_CAPTION with imageinwords

Usage

Single Image

from PIL import Image
from transformers import AutoProcessor, AutoModelForCausalLM

name = "yayayaaa/florence-2-large-ft-moredetailed"
model = AutoModelForCausalLM.from_pretrained(name, trust_remote_code=True).to("cuda").eval()
processor = AutoProcessor.from_pretrained(name, trust_remote_code=True)

prompt = "<MORE_DETAILED_CAPTION>"
filename = 'test.jpg'
image = Image.open(filename).convert('RGB')

inputs = processor(text=prompt, images=image, return_tensors="pt").to("cuda")

generated_ids = model.generate(
    input_ids=inputs["input_ids"],
    pixel_values=inputs["pixel_values"],
    max_new_tokens=1024,
    do_sample=False,

)
print(processor.batch_decode(generated_ids, skip_special_tokens=True)[0])
