Libraries

How to use microsoft/Florence-2-large with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="microsoft/Florence-2-large", trust_remote_code=True)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("microsoft/Florence-2-large", trust_remote_code=True)
model = AutoModelForImageTextToText.from_pretrained("microsoft/Florence-2-large", trust_remote_code=True)

vLLM

How to use microsoft/Florence-2-large with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "microsoft/Florence-2-large"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "microsoft/Florence-2-large",
		"prompt": "Once upon a time,",
		"max_tokens": 512,
		"temperature": 0.5
	}'

Use Docker

docker model run hf.co/microsoft/Florence-2-large

SGLang

How to use microsoft/Florence-2-large with SGLang:

Install from pip and serve model

# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "microsoft/Florence-2-large" \
    --host 0.0.0.0 \
    --port 30000
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:30000/v1/completions" \

Batch: inefficient memory

A batch size of 10 eats 40GB of VRAM!

VRAM Allocated: 3147.43 MB
VRAM Reserved: 39532.00 MB

model_name = "microsoft/Florence-2-large-ft"
model = AutoModelForCausalLM.from_pretrained(model_name, trust_remote_code=True).to('cuda')
processor = AutoProcessor.from_pretrained(model_name, trust_remote_code=True)


def generate_batch(prompts, images):
    # Process inputs in batches
    inputs = processor(text=prompts, images=images, 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,
        num_beams=3
    )

    generated_texts = processor.batch_decode(generated_ids, skip_special_tokens=False)
    parsed_answers = [
        processor.post_process_generation(text, task="<OD>", image_size=(img.width, img.height))
        for text, img in zip(generated_texts, images)
    ]

    return parsed_answers, generated_ids

Even when I repurpose the colab exactly as-is, VRAM usage seems to linearly grow with batch size.

Any help is greatly appreciated

Wrap the call to model.generate() into a torch.no_grad() context manager:

with torch.no_grad():
    generated_ids = model.generate(
        input_ids=inputs["input_ids"],
        pixel_values=inputs["pixel_values"],
        max_new_tokens=1024,
        do_sample=False,
        num_beams=3,
    )
