Records only ["data/*/records.jsonl"]
One label ["data/graphic_media/**", "data/media/graphic_media/**"]
Images only ["data/*/records.jsonl", "data/media/*/images/**"]
# Example: records only
snapshot_download(
    repo_id        = "usermodsky/bskymoddata",
    repo_type      = "dataset",
    local_dir      = "./bskymoddata",

⚠️ Full download includes all graphic media. Estimated size: >50 GB.

Single file:

local_path = hf_hub_download(
    repo_id   = "usermodsky/bskymoddata",
    repo_type = "dataset",
    filename  = "data/media/graphic_media/images/hy/bafkrei...hy.jpeg",

Usage

from datasets import load_dataset

ds = load_dataset("usermodsky/bskymoddata", "graphic_media", split="train")
# or: "intolerant"
import pandas as pd
df = pd.read_json("hf://datasets/usermodsky/bskymoddata/data/graphic_media/records.jsonl", lines=True)

Filter subsets:

# Posts with images
with_images = ds.filter(lambda x: len(x["images"]) > 0)

# Text-only posts
text_only = ds.filter(lambda x: len(x["images"]) == 0 and x["video"] is None)

# Reply posts only
replies = ds.filter(lambda x: x["record"].get("reply") is not None)

# English posts
en = ds.filter(lambda x: "en" in (x["record"].get("langs") or []))
