Tiny-OBELICS (Debug Dataset)

Tiny-OBELICS is a curated, 100% offline-compatible multimodal debug dataset of interleaved document-image examples drawn from the first shard of HuggingFaceM4/OBELICS.

All image bytes are stored directly inside the Parquet shards using Hugging Face's native Image feature type. No CDN dependencies, no dead links, no download bubbles at training time.

Dataset Structure

Parallel-lists layout matching the original OBELICS schema.

Column Type Description
texts list[str|null] Text segments interleaved with images
images list[image|null] PIL images (or None for text-only slots)
metadata list[struct|null] Per-image metadata (dimensions, src, alt-text, …)
general_metadata struct Document-level crawl info (url, warc offset/length)

Shard Policy

  • Shards are bounded by raw image byte size (~25MB per shard), not by row count.
  • Any document where one or more images failed to download is discarded entirely.
  • Images are converted to RGB and have metadata stripped to ensure clean serialization.
  • Original image width and height are always calculated directly from the verified PIL image object.

Usage

from datasets import load_dataset

# Load train split
ds_train = load_dataset("akzsh/tiny-obelics", split="train")
print(ds_train)

# Load validation split
ds_val = load_dataset("akzsh/tiny-obelics", split="validation")
print(ds_val)

row = ds_train[0]
for text, img in zip(row["texts"], row["images"]):
    if text: print("[Text]", text[:80])
    elif img: print("[Image]", img.size)
