🚀 Quick Start

Installation

Option 1: From PyPI (Recommended for Users)

# For Secret-Learn with JAX acceleration
pip install Secret-Learn

# For privacy-preserving features, install SecretFlow
# Note: Requires Python 3.10
pip install -U secretflow

Option 2: Using Conda (Recommended for SecretFlow)

# Create environment with Python 3.10
conda create -n sf python=3.10
conda activate sf

# Install SecretFlow
pip install -U secretflow

# Install Secret-Learn
pip install Secret-Learn

Option 3: From Source (Recommended for Developers)

# Clone repository
git clone https://github.com/chenxingqiang/Secret-Learn.git
cd Secret-Learn

# Create conda environment
conda create -n sf python=3.10
conda activate sf

# Install dependencies
pip install -U secretflow
pip install -e .

Quick Start

Secret-Learn provides 573 privacy-preserving ML algorithms through three modes:

FL Mode: Federated Learning (data stays local)
SL Mode: Split Learning (collaborative training)
SS Mode: Secret Sharing (maximum privacy with MPC)

# Run FL example (easiest to start)
python examples/FL/linear_regression.py

# Run other examples
python examples/FL/kmeans.py
python examples/SL/random_forest_classifier.py

# For maximum privacy (SS mode - requires multi-party)
# Terminal 1: python examples/SS/pca.py --party bob
# Terminal 2: python examples/SS/pca.py --party alice

SecretFlow Privacy-Preserving Usage

⚠️ Important: SecretFlow 1.14+ removed simulation mode. Use the provided example scripts instead of manual REPL initialization.

Recommended: Use Pre-Built Examples

The easiest way to get started is running the complete examples:

# FL Mode - Best for learning (works in examples)
python examples/FL/linear_regression.py      # Linear regression
python examples/FL/kmeans.py                 # Clustering  
python examples/FL/random_forest_classifier.py  # Ensemble

# SL Mode - Split learning examples
python examples/SL/mlp_classifier.py
python examples/SL/linear_regression.py

# SS Mode - Requires multi-party setup (highest security)
# Terminal 1 (Bob):
python examples/SS/pca.py --party bob

# Terminal 2 (Alice):  
python examples/SS/pca.py --party alice

Why Use Example Scripts?

SecretFlow 1.14+ uses PRODUCTION mode which requires:

Proper cluster configuration
Network initialization
Multi-party coordination

The example scripts handle all this complexity for you. For custom code, use the examples as templates.

See complete working examples in:

examples/SL/ - 191 SL examples
examples/SS/ - 191 SS examples

🛠 Installation

Prerequisites

Choose Your JAX Backend

# CPU only (default)
pip install jax jaxlib

# GPU (CUDA)
pip install jax[gpu]

# TPU (Google Cloud)
pip install jax[tpu] -f https://storage.googleapis.com/jax-releases/libtpu_releases.html

Install Secret-Learn

# From PyPI (recommended)
pip install Secret-Learn

# With SecretFlow for privacy-preserving ML
pip install Secret-Learn[secretflow]

# From source (development)
git clone https://github.com/chenxingqiang/Secret-Learn.git
cd Secret-Learn
pip install -e .

Verify Installation

# Test Secret-Learn installation
import secretlearn
print(f"Secret-Learn Version: {secretlearn.__version__}")
print("Secret-Learn installed: ✅")

# Test SecretFlow integration
try:
    import secretflow as sf
    print(f"SecretFlow Version: {sf.__version__}")
    print("SecretFlow installed: ✅")
except ImportError:
    print("SecretFlow not installed. Run: pip install secretflow")

# Test algorithm import (FL mode)
try:
    from secretlearn.FL.linear_models.linear_regression import FLLinearRegression
    print("FL algorithms available: ✅")
except ImportError as e:
    print(f"Import error: {e}")

# Quick functionality test - run an example
print("\nTo test functionality, run an example:")
print("  python examples/FL/linear_regression.py")

🎯 Usage Examples

1. Federated Learning Mode (FL)

FL mode keeps data local while enabling collaborative learning:

# Run complete FL example
python examples/FL/linear_regression.py

The example demonstrates:

Local data computation on each party's PYU device
Secure model aggregation
Privacy-preserving predictions
JAX acceleration for local training

2. Privacy-Preserving FL Mode (Federated)

FL Mode works with single-process simulation (best for learning and testing):

# Run existing FL examples - no complex setup needed!
# These work out of the box:
# python examples/FL/linear_regression.py
# python examples/FL/kmeans.py
# python examples/FL/random_forest_classifier.py

# For custom FL code, see examples/FL/ directory
# FL mode simulates federation in a single process

For production FL deployments, use the production mode setup shown above with PYU devices.

3. Maximum Privacy SS Mode (MPC Encrypted)

SS Mode requires multi-party setup with SecretFlow's MPC engine:

# Run existing SS examples (multi-process required):
# Terminal 1 - Bob
python examples/SS/adaboost_classifier.py --party bob

# Terminal 2 - Alice  
python examples/SS/adaboost_classifier.py --party alice

# Each party's data stays completely private with full MPC protection

See examples/SS/ directory for 191 complete SS mode examples.
