ElixirDatasets

ElixirDatasets is a comprehensive library for accessing and managing datasets from Hugging Face Hub in Elixir. Inspired by the Python datasets library, it brings powerful dataset management capabilities to the Elixir ecosystem with seamless integration with Explorer DataFrames.

✨ Features

🚀 Easy Access to Hugging Face Hub - Load thousands of datasets with a single function call
📊 Explorer Integration - Automatic conversion to Explorer DataFrames for data manipulation
💾 Smart Caching - Intelligent local caching to avoid redundant downloads
🌊 Streaming Support - Process large datasets without loading everything into memory
📤 Upload Datasets - Publish your own datasets to Hugging Face Hub
🔒 Private Repositories - Full support for authentication and private datasets
🎯 Multiple Formats - Support for CSV, Parquet, and JSONL files

📦 Installation

Add elixir_datasets to your list of dependencies in mix.exs:

def deps do
  [
    {:elixir_datasets, "~> 0.1.0"}
  ]
end

🚀 Quick Start

{:ok, [train_df]} = ElixirDatasets.load_dataset(
  {:hf, "cornell-movie-review-data/rotten_tomatoes"},
  split: "train"
)

{:ok, datasets} = ElixirDatasets.load_dataset({:local, "./data"})

{:ok, stream} = ElixirDatasets.load_dataset(
  {:hf, "stanfordnlp/imdb", subdir: "plain_text"},
  split: "train",
  streaming: true
)

stream |> Enum.take(100) |> IO.inspect()
