# 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. |
