glutamate

Easy to use Python library for querying and downloading posts from e621.net.

Installation

pip install glutamate

Example

from pathlib import Path

from glutamate.database import E621, E621Data, E621PostsCSV, E621TagsCSV, Query, autoinit_from_directory
from glutamate.dataset import get_captions, write_captions, write_stats
from glutamate.download import download_posts


# Init with qualified file paths
e621_data_directory = Path('./e621-data/')
posts_csv = e621_data_directory / 'posts.csv'
posts = E621PostsCSV(posts_csv)
tags_csv = e621_data_directory / 'tags.csv'
tags = E621TagsCSV(tags_csv)
e621: E621 = E621Data(posts, tags)

# or simple automatic init with directory contains CSVs
e621_data_directory = Path('./e621-data/')
e621 = autoinit_from_directory(e621_data_directory)

query = Query(("kisha", "solo"))
kisha_dataset = e621.select(query)

target_directory = Path().cwd() / 'tmp' / 'kisha_solo'
target_directory.mkdir(parents=True, exist_ok=True)

results = download_posts(posts, target_directory, naming='id')
failed = [result for result in results if not result.ok]
if failed:
    print(f"Failed to download {len(failed)} posts")

captions = kisha_dataset.get_captions(
    naming='id',
    remove_underscores=True,
    tags_to_head=('kisha', 'kisha (character)')
)
write_captions(captions, target_directory)

counts_csv = target_directory / 'tags.csv'
counts = kisha_dataset.get_tags_stats()
write_stats(counts, counts_csv)
