Barzooka (Hugging Face Space)

This Space wraps the Barzooka tool to screen PDFs or images and detect graph types (bar, bardot, box, dot, violin, hist, pie, flow, text, other).

• Upstream repo: https://github.com/quest-bih/barzooka
• Dependencies in Spaces:
  • Python: pinned in requirements.txt
  • System: poppler-utils via packages.txt (provides pdftocairo)

Usage

1. Single PDF tab: upload a PDF and choose aggregated vs page-wise output.
2. ZIP of PDFs tab: upload a .zip with multiple PDFs and download a CSV of results.
3. Images tab: upload JPG/PNG images to classify each page image directly.

Model file (barzooka.pkl)

If the installed package did not include the model (Git-LFS), upload barzooka.pkl next to app.py or set the environment variable BARZOOKA_MODEL_URL to a direct downloadable URL.

Notes

• Barzooka relies on pdftocairo to convert PDF pages to images. This Space installs poppler-utils automatically.
• FastAI .pkl files are sensitive to library versions; we pin fastai/torch/torchvision accordingly.
• Torch may require NumPy < 2; we pin numpy==1.26.4 to avoid ABI mismatches.
