Are you fascinated by the convergence of computer vision and natural language processing? Enter Florence-2, an advanced vision foundation model by Microsoft that takes a prompt-based approach to tackle diverse tasks in vision and vision-language realms. In this blog, we will explore the model, how to get started, and troubleshoot common issues!
Model Summary
The Florence-2 model utilizes a comprehensive technical framework to interpret simple text prompts for various applications, including captioning, object detection, and segmentation. This model is built upon the impressive FLD-5B dataset, boasting 5.4 billion annotations spanning 126 million images. The sequence-to-sequence architecture illustrates Florence-2’s versatility in both zero-shot and fine-tuning settings, making it a robust player in the world of vision tasks.
How to Get Started with the Model
Ready to dive into Florence-2? Here’s a simple and user-friendly guide to get you started!
import requests
from PIL import Image
from transformers import AutoProcessor, AutoModelForCausalLM
device = "cuda:0" if torch.cuda.is_available() else "cpu"
torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
model = AutoModelForCausalLM.from_pretrained("microsoft/Florence-2-large-ft", torch_dtype=torch_dtype, trust_remote_code=True).to(device)
processor = AutoProcessor.from_pretrained("microsoft/Florence-2-large-ft", trust_remote_code=True)
prompt = ""
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/car.jpg?download=true"
image = Image.open(requests.get(url, stream=True).raw)
inputs = processor(text=prompt, images=image, return_tensors="pt").to(device, torch_dtype)
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_text = processor.batch_decode(generated_ids, skip_special_tokens=False)[0]
parsed_answer = processor.post_process_generation(generated_text, task="", image_size=(image.width, image.height))
print(parsed_answer)
The above code is your magic wand! As a computer scientist applies a methodical approach to solving complex algebra problems step-by-step, this code enables you to work with visual data effectively. Think of the image and prompt as ingredients in a recipe. The code orchestrates the gathering of these ingredients, feeding them into a “chef” (the model) that skillfully crafts a delicious output (the parsed answer).
Tasks
The beauty of Florence-2 resides in its ability to flexibly perform various tasks merely by changing the prompts. Below are some demos categorized for easy execution:
- Captioning:
prompt = "
" run_example(prompt) - Object Detection:
prompt = "
" run_example(prompt) - Dense Region Caption:
prompt = "
" run_example(prompt) - OCR:
prompt = "
" run_example(prompt)
Troubleshooting
If you encounter any issues during the setup or execution, consider these troubleshooting ideas to get you through:
- Ensure that you have the latest version of the
transformers
library installed. - Check that your GPU is properly set up if you’re planning to run the model with CUDA.
- If you receive an error regarding model loading, confirm that the model name is correctly specified.
- If the outputs aren’t as expected, consider fine-tuning your prompts or try adjusting model settings.
