"Machine Learning for Drug Discovery" - Code and Data Repository

👋 Welcome to the Machine Learning for Drug Discovery Repository

This repository contains code and data for the first edition of Machine Learning for Drug Discovery (Manning Publications). The companion material within this repository covers introductory topics at the intersection of machine learning, deep learning, and drug discovery applied to real world scenarios in each chapter. The code and notebooks are released under the Apache 2.0 license.

For readability, the chapter notebooks only contain runnable code blocks and section titles. They omit the rest of the material in the book, i.e., text paragraphs, figures (unless generated as part of one of the code blocks), equations, and pseudocode. If you want to be able to follow what's going on, I recommend reading the notebooks side-by-side with your copy of the book!

🚧 Under Construction

Note that this project is a work in progress and notebooks will be released as they are drafted. We anticipate a full release of the book in Winter 2025. We recommend interacting with notebooks through Colab.

Purchase of the book through Manning's Early Access Program (MEAP) guarantees access to current and future chapters. I appreciate your patience and support!

Encounter any issues? Please let me know -- I can't fix a problem if I am not aware of its existence!

💻 Getting Started

Option 1: Google Colab (No Installation Required)

Open any notebook in Colab and run the installation cells at the top!

Each notebook includes two Colab installation options:

• Quick Install: Fast pip-based setup (3-10 minutes) with only the packages needed for that chapter
• Full Install: Complete conda environment (15-20 minutes) with all packages for all chapters

Option 2: Local Installation

Prerequisites: Python 3.12+ and git

We provide tiered installation options so you can install only what you need:

🟢 Core Environment (Chapters 1-4) — Basic ML & QSAR

git clone https://github.com/nrflynn2/ml-drug-discovery.git
cd ml-drug-discovery
pip install -r requirements-core.txt

Includes: numpy, pandas, matplotlib, seaborn, rdkit, scikit-learn

🟡 Advanced Environment (Chapters 5-8) — Gradient Boosting & Deep Learning

pip install -r requirements-advanced.txt

Adds: torch, xgboost, lightgbm, catboost, shap, umap, statsmodels

🔴 Full Environment (Chapters 9-11) — Molecular Docking & GNNs

conda env create -f ml4dd2025.yml
conda activate ml4dd2025

Adds: openmm, vina, pdbfixer, torch-geometric, mdtraj, prolif, meeko

Note: Chapters 9-11 require conda due to specialized packages (molecular dynamics, docking) that don't install reliably via pip.

Quick Reference:

• Chapter 1-4: Use requirements-core.txt
• Chapter 5-8, Appendix C: Use requirements-advanced.txt
• Chapter 9-11: Use ml4dd2025.yml (conda required)
• All chapters: Use ml4dd2025.yml for complete setup

For detailed installation instructions and troubleshooting, see INSTALL.md.
