Libra-81K-SFT

This dataset contains:

• data/images/: split image archives (*.tar.gz.part-*)
• data/annotations/: JSON annotation files

---

Download Dataset

1) Install Git LFS

git lfs install

2) Clone the dataset repo

git clone https://huggingface.co/datasets/GUI-Libra/GUI-Libra-81K-SFT
cd GUI-Libra-81K-SFT

Reconstruct and extract image archives

Folder structure

After cloning, you should see:

• data/images/ containing *.tar.gz.part-*
• data/annotations/ containing *.json

1) Merge split parts into .tar.gz

This will create merged archives under data/images_archives/.

cd data/images
mkdir -p ../images_archives ../images_extracted

for base in $(ls *.tar.gz.part-* | sed -E 's/\.part-[0-9]+$//' | sort -u); do
  echo "[MERGE] $base.part-* -> ../images_archives/$base"
  cat "${base}".part-* > "../images_archives/${base}"
done

2) Extract each merged archive

This will extract each archive into a separate directory under data/images_extracted/.

cd ../images_archives
for tgz in *.tar.gz; do
  name="${tgz%.tar.gz}"
  mkdir -p "../images_extracted/${name}"
  echo "[EXTRACT] $tgz -> ../images_extracted/${name}"
  tar -xzf "$tgz" -C "../images_extracted/${name}"
done

After extraction, images will be available under:

• data/images_extracted/<archive_name>/...

---

Load annotations in Python

import json
from pathlib import Path

ann_dir = Path("data/annotations")
all_json = {}

for p in sorted(ann_dir.glob("*.json")):
    with open(p, "r", encoding="utf-8") as f:
        all_json[p.name] = json.load(f)

print("Loaded json files:", len(all_json))
print("Example keys:", list(all_json.keys())[:5])

---

Notes

• Each *.tar.gz.part-* group must be merged in order before extraction.

• If you only need one subset (e.g., gui-odyssey), you can merge/extract only that prefix:

  cd data/images
  cat gui-odyssey.tar.gz.part-* > ../images_archives/gui-odyssey.tar.gz
  tar -xzf ../images_archives/gui-odyssey.tar.gz -C ../images_extracted/gui-odyssey
