Getting Started

To use nemotron-parse via the Nvidia API, set the NVIDIA_API_KEY environment variable.

Then to directly access the reader:

from paperqa.types import ParsedText
from paperqa_nemotron import parse_pdf_to_pages

async def main(pdf_path) -> ParsedText:
    return await parse_pdf_to_pages(pdf_path)

Or use the reader within PaperQA:

from paperqa import Docs, PQASession, Settings

from paperqa_nemotron import parse_pdf_to_pages


async def main(pdf_path, question: str | PQASession) -> PQASession:
    settings = Settings(parsing={"parse_pdf": parse_pdf_to_pages})
    docs = Docs()
    await docs.aadd(pdf_path, settings=settings)
    return await docs.aquery(question, settings=settings)
