Example Notebooks

This directory contains Jupyter notebooks demonstrating AstroML's core functionality for Stellar blockchain graph ML.

Prerequisites

Before running any notebook, install the project and its dependencies:

# From the repository root
pip install -r requirements.txt
pip install -e .

Kernel Setup

Make sure your Jupyter kernel uses the virtual environment where AstroML is installed:

python -m ipykernel install --user --name=astroml --display-name="Python (astroml)"

Notebooks

Notebook Description
01_getting_started.ipynb End-to-end walkthrough: ingestion → graph → training
02_fraud_detection.ipynb Fraud pattern injection, Deep SVDD, and GNN scoring
03_transaction_graph_analysis.ipynb Temporal snapshots, structural importance, and feature engineering

Verifying Your Setup

Each notebook starts with a dependency-check cell that validates all required packages are importable. If that cell produces warnings, install the missing dependencies before proceeding.

Troubleshooting

  • ModuleNotFoundError: No module named 'astroml' — run pip install -e . from the repository root, or add the root to sys.path (see the first code cell of each notebook).
  • Missing torch / torch_geometric — install via pip install -r requirements-cpu.txt (CPU) or follow instructions at pytorch.org for a CUDA build.
