Generated from D:\Unreal Engine Environments\game_trial\Content\Python\unreal-scene-gen\unreal-secene-gen\dataset on 2026-03-09T23:50:37.742993+00:00.

Summary

• Format: parquet shards with one row per sample.
• Split: train only.
• Images are embedded in parquet under the image struct column (bytes, path).
• Full raw metadata is preserved in raw_params_json.

Run Stats

• Discovered paired samples: 119502
• New rows prepared this run: 20000
• Skipped because already uploaded: 99502
• Skipped broken/missing pairs or parse errors: 0
• Parquet shards written this run: 79

Loading

from datasets import load_dataset, Image

ds = load_dataset("turhancan97/SpaRRTa", split="train")
# Convert struct column to datasets Image feature if needed:
ds = ds.cast_column("image", Image())

Download to Local Machine

Download the dataset repo files (parquet shards, README, manifest):

huggingface-cli download turhancan97/SpaRRTa --repo-type dataset --local-dir ./hf_SpaRRTa

Rebuild Original Folder Structure

The script below reconstructs: <output>/<scene_variant>/img_XXXX.jpg and params_XXXX.json

from pathlib import Path
from datasets import load_dataset, Image

repo_id = "turhancan97/SpaRRTa"
output_root = Path("restored_position_between_objects")
output_root.mkdir(parents=True, exist_ok=True)

ds = load_dataset(repo_id, split="train")
ds = ds.cast_column("image", Image(decode=False))

for row in ds:
    mid = output_root / row["scene_variant"]
    mid.mkdir(parents=True, exist_ok=True)

    image_name = Path(row["image_relpath"]).name
    params_name = Path(row["params_relpath"]).name

    image_bytes = row["image"]["bytes"]
    if image_bytes is None:
        raise RuntimeError(f"Missing embedded image bytes for {row['sample_id']}")

    (mid / image_name).write_bytes(image_bytes)
    (mid / params_name).write_text(row["raw_params_json"], encoding="utf-8")
