Decentralized Hugging Face - AI models and datasets from IPFS/Filecoin

DeHug - Decentralized Hugging Face

DeHug is a decentralized platform for AI models and datasets built on IPFS/Filecoin, providing a decentralized alternative to traditional centralized AI model repositories.

Features

• 🌐 Decentralized Storage: Models and datasets stored on IPFS/Filecoin
• 🔒 Censorship Resistant: No single point of failure or control
• 🚀 Easy Integration: Simple Python SDK compatible with existing workflows
• 📊 Data Loading: Support for JSON, CSV, text, and binary formats
• 🔍 Search: Search and discover models and datasets
• 📋 Metadata: Rich metadata support for models and datasets

Installation

pip install dehug

Quick Start

Loading Datasets

from dehug import DeHug

client = DeHug()

# Load a CSV dataset
dataset = client.load_dataset("QmYourDatasetCID", format_hint="csv")
print(dataset.head())

# Load a JSON dataset
data = client.load_dataset("QmYourJSONDataCID", format_hint="json")
print(data)

# Load by name (if registered in DeHug registry)
dataset = client.load_dataset("my-dataset-name", format_hint="csv")

Working with Models

# Load model metadata
model_info = client.load_model("QmYourModelCID")
print(f"Model: {model_info['name']}")
print(f"Task: {model_info['task']}")
print(f"Description: {model_info['description']}")

# Download model files locally
model_path = client.download_model("QmYourModelCID", "./my_models")
print(f"Model downloaded to: {model_path}")

Listing and Searching

# List all available datasets
datasets = client.list_datasets()
for dataset in datasets:
    print(f"{dataset['name']}: {dataset['description']}")

# List all available models
models = client.list_models()
for model in models:
    print(f"{model['name']}: {model['task']}")

# Search for datasets
results = client.search_datasets("sentiment analysis")
print(f"Found {len(results)} datasets")

# Search for models
results = client.search_models("text classification")
print(f"Found {len(results)} models")

CLI Usage

DeHug includes a command-line interface for easy access:

# Load and display a dataset
dehug dataset QmYourDatasetCID --format csv

# Save dataset to file
dehug dataset QmYourDatasetCID --format csv --output dataset.csv

# Load model metadata
dehug model QmYourModelCID

# Download model files
dehug model QmYourModelCID --download ./models

# List available datasets
dehug list datasets

# List available models
dehug list models

# Search for datasets
dehug search datasets "machine learning"

# Search for models
dehug search models "nlp"

Configuration

You can customize the IPFS gateway and API endpoints by passing a config dictionary:

config = {
    'ipfs_gateway': 'https://your-ipfs-gateway.com/ipfs',
    'contract_api': 'https://your-api.com',
    'request_timeout': 60
}

client = DeHug(config=config)

Default configuration:

• IPFS Gateway: https://ipfs.io/ipfs
• Contract API: https://api.dehug.io
• Request Timeout: 30 seconds

Supported Formats

DeHug automatically detects and handles various data formats:

• JSON: Parsed into Python dictionaries
• CSV: Loaded as pandas DataFrames
• Text: Returned as strings
• Binary: Returned as bytes

You can also specify format hints for better performance:

# Explicitly specify format
csv_data = client.load_dataset("QmDataCID", format_hint="csv")
json_data = client.load_dataset("QmDataCID", format_hint="json")
text_data = client.load_dataset("QmDataCID", format_hint="text")
binary_data = client.load_dataset("QmDataCID", format_hint="binary")

Error Handling

DeHug provides specific exceptions for better error handling:

from dehug import DeHug, DeHugError, NetworkError, DatasetNotFoundError

client = DeHug()

try:
    dataset = client.load_dataset("nonexistent-dataset")
except DatasetNotFoundError:
    print("Dataset not found")
except NetworkError:
    print("Network connection failed")
except DeHugError as e:
    print(f"DeHug error: {e}")

API Reference

DeHug Client

• load_dataset(name_or_cid, format_hint=None): Load dataset from IPFS
• load_model(name_or_cid): Load model metadata
• download_model(name_or_cid, download_dir="./models"): Download model files
• list_datasets(): List available datasets
• list_models(): List available models
• search_datasets(query): Search datasets by query
• search_models(query): Search models by query

Utility Functions

• load_dataset_from_cid(cid, format_hint=None): Direct dataset loading from CID
• load_content_from_cid(cid, format_hint=None): Load any content from CID

Architecture

DeHug consists of two main components:

1. Contract API: Metadata registry for models and datasets
2. IPFS Storage: Decentralized storage for actual model/data files

The SDK provides a seamless interface to both layers, allowing you to work with decentralized AI assets as easily as with traditional centralized repositories.
