Parse PDF documents into markdown formatted content using Vision LLMs

Vision Parse

🚀 Parse PDF documents into beautifully formatted markdown content using state-of-the-art Vision Language Models - all with just a few lines of code!

🎯 Introduction

Vision Parse harnesses the power of Vision Language Models to revolutionize document processing:

• 📝 Scanned Document Processing: Intelligently identifies and extracts text, tables, and LaTeX equations from scanned documents into markdown-formatted content with high precision
• 🎨 Advanced Content Formatting: Preserves LaTeX equations, hyperlinks, images, and document hierarchy for markdown-formatted content
• 🤖 Multi-LLM Support: Seamlessly integrates with multiple Vision LLM providers such as OpenAI, Gemini, and Llama for optimal accuracy and speed
• 📁 Local Model Hosting: Supports local model hosting with Ollama for secure, no-cost, private, and offline document processing

🚀 Getting Started

Prerequisites

• 🐍 Python >= 3.9
• 🖥️ Ollama (if you want to use local models)
• 🤖 API Key for OpenAI or Google Gemini (if you want to use OpenAI or Google Gemini)

Installation

Install the core package using pip (Recommended):

pip install vision-parse

Install the additional dependencies for OpenAI or Gemini:

# For OpenAI support
pip install 'vision-parse[openai]'

# For Gemini support
pip install 'vision-parse[gemini]'

# To install all the additional dependencies
pip install 'vision-parse[all]'

Install the package from source:

pip install 'git+https://github.com/iamarunbrahma/vision-parse.git#egg=vision-parse[all]'

Setting up Ollama (Optional)

See examples/ollama_setup.md on how to setup Ollama locally.

⌛️ Usage

Basic Example Usage

from vision_parse import VisionParser

# Initialize parser
parser = VisionParser(
    model_name="llama3.2-vision:11b", # For local models, you don't need to provide the api key
    temperature=0.4,
    top_p=0.5,
    image_mode="url", # Image mode can be "url", "base64" or None
    detailed_extraction=False, # Set to True for more detailed extraction
    enable_concurrency=False, # Set to True for parallel processing
)

# Convert PDF to markdown
pdf_path = "path/to/your/document.pdf" # local path to your pdf file
markdown_pages = parser.convert_pdf(pdf_path)

# Process results
for i, page_content in enumerate(markdown_pages):
    print(f"\n--- Page {i+1} ---\n{page_content}")

Customize Ollama configuration for better performance

from vision_parse import VisionParser

custom_prompt = """
Strictly preserve markdown formatting during text extraction from scanned document.
"""

# Initialize parser with Ollama configuration
parser = VisionParser(
    model_name="llama3.2-vision:11b",
    temperature=0.7,
    top_p=0.6,
    num_ctx=4096,
    image_mode="base64",
    custom_prompt=custom_prompt,
    detailed_extraction=True,
    ollama_config={
        "OLLAMA_NUM_PARALLEL": "8",
        "OLLAMA_REQUEST_TIMEOUT": "240.0",
    },
    enable_concurrency=True,
)

# Convert PDF to markdown
pdf_path = "path/to/your/document.pdf"
markdown_pages = parser.convert_pdf(pdf_path)

OpenAI or Gemini Model Usage

from vision_parse import VisionParser

# Initialize parser with OpenAI model
parser = VisionParser(
    model_name="gpt-4o",
    api_key="your-openai-api-key", # Get the OpenAI API key from https://platform.openai.com/api-keys
    temperature=0.7,
    top_p=0.4,
    image_mode="url",
    detailed_extraction=True, # Set to True for more detailed extraction
    enable_concurrency=True,
)

# Initialize parser with Google Gemini model
parser = VisionParser(
    model_name="gemini-1.5-flash",
    api_key="your-gemini-api-key", # Get the Gemini API key from https://aistudio.google.com/app/apikey
    temperature=0.7,
    top_p=0.4,
    image_mode="url",
    detailed_extraction=True, # Set to True for more detailed extraction
    enable_concurrency=True,
)
