sparrow-parse 0.3.8

Sparrow Parse is a Python package (part of Sparrow) for parsing and extracting information from documents.

Sparrow Parse

Description

This module implements Sparrow Parse library library with helpful methods for data pre-processing, parsing and extracting information. This library relies on Visual LLM functionality, Table Transformers and is part of Sparrow. Check main README

Install

pip install sparrow-parse

Parsing and extraction

Sparrow Parse VL (vision-language model) extractor with Hugging Face GPU infra

# run locally: python -m sparrow_parse.extractors.vllm_extractor

from sparrow_parse.vllm.inference_factory import InferenceFactory
from sparrow_parse.extractors.vllm_extractor import VLLMExtractor

extractor = VLLMExtractor()

# export HF_TOKEN="hf_"
config = {
    "method": "huggingface",  # Could be 'huggingface' or 'local_gpu'
    "hf_space": "katanaml/sparrow-qwen2-vl-7b",
    "hf_token": os.getenv('HF_TOKEN'),
    # Additional fields for local GPU inference
    # "device": "cuda", "model_path": "model.pth"
}

# Use the factory to get the correct instance
factory = InferenceFactory(config)
model_inference_instance = factory.get_inference_instance()

input_data = [
    {
        "file_path": "/data/oracle_10k_2014_q1_small.pdf",
        "text_input": "retrieve {"table": [{"description": "str", "latest_amount": 0, "previous_amount": 0}]}. return response in JSON format"
    }
]

# Now you can run inference without knowing which implementation is used
results_array, num_pages = extractor.run_inference(model_inference_instance, input_data, generic_query=False,
                                 debug_dir="/data/",
                                 debug=True,
                                 mode=None)

for i, result in enumerate(results_array):
    print(f"Result for page {i + 1}:", result)
print(f"Number of pages: {num_pages}")

Use mode="static" if you want to simulate LLM call, without executing LLM backend.

Method run_inference will return results and number of pages processed.

Note: GPU backend katanaml/sparrow-qwen2-vl-7b is private, to be able to run below command, you need to create your own backend on Hugging Face space using code from Sparrow Parse.

PDF pre-processing

from sparrow_parse.extractor.pdf_optimizer import PDFOptimizer

pdf_optimizer = PDFOptimizer()

num_pages, output_files, temp_dir = pdf_optimizer.split_pdf_to_pages(file_path,
                                                                     output_directory,
                                                                     convert_to_images)

Example:

file_path - /data/invoice_1.pdf

output_directory - set to not None, for debug purposes only

convert_to_images - default False, to split into PDF files

Library build

Commercial usage

Sparrow is available under the GPL 3.0 license, promoting freedom to use, modify, and distribute the software while ensuring any modifications remain open source under the same license. This aligns with our commitment to supporting the open-source community and fostering collaboration.

Additionally, we recognize the diverse needs of organizations, including small to medium-sized enterprises (SMEs). Therefore, Sparrow is also offered for free commercial use to organizations with gross revenue below $5 million USD in the past 12 months, enabling them to leverage Sparrow without the financial burden often associated with high-quality software solutions.

For businesses that exceed this revenue threshold or require usage terms not accommodated by the GPL 3.0 license—such as integrating Sparrow into proprietary software without the obligation to disclose source code modifications—we offer dual licensing options. Dual licensing allows Sparrow to be used under a separate proprietary license, offering greater flexibility for commercial applications and proprietary integrations. This model supports both the project's sustainability and the business's needs for confidentiality and customization.

If your organization is seeking to utilize Sparrow under a proprietary license, or if you are interested in custom workflows, consulting services, or dedicated support and maintenance options, please contact us at [e-mail]. We're here to provide tailored solutions that meet your unique requirements, ensuring you can maximize the benefits of Sparrow for your projects and workflows.
