Machine Learning Notebooks, 3rd edition This project aims at teaching you the fundamentals of Machine Learning in python. It contains the example code and solutions to the exercises in the third edition of my O'Reilly book Hands-on Machine Learning with Scikit-Learn, Keras and TensorFlow (3rd edition):

Note: If you are looking for the second edition notebooks, check out ageron/handson-ml2. For the first edition, see ageron/handson-ml. Quick Start Want to play with these notebooks online without having to install anything?

(recommended)

⚠ Colab provides a temporary environment: anything you do will be deleted after a while, so make sure you download any data you care about. Details Other services may work as well, but I have not fully tested them:

Just want to quickly look at some notebooks, without executing any code?

github.com's notebook viewer also works but it's not ideal: it's slower, the math equations are not always displayed correctly, and large notebooks often fail to open.

Want to run this project using a Docker image? Read the Docker instructions. Want to install this project on your own machine? Start by installing Anaconda (or Miniconda), git, and if you have a TensorFlow-compatible GPU, install the GPU driver, as well as the appropriate version of CUDA and cuDNN (see TensorFlow's documentation for more details). Next, clone this project by opening a terminal and typing the following commands (do not type the first signsoneachline,theyjustindicatethattheseareterminalcommands):signs on each line, they just indicate that these are terminal commands): git clone https://github.com/ageron/handson-ml3.git $ cd handson-ml3

Next, run the following commands: condaenvcreatefenvironment.ymlconda env create -f environment.yml conda activate homl3 $ python -m ipykernel install --user --name=python3

Finally, start Jupyter: $ jupyter notebook

If you need further instructions, read the detailed installation instructions. FAQ Which Python version should I use? I recommend Python 3.10. If you follow the installation instructions above, that's the version you will get. Any version ≥3.7 should work as well. I'm getting an error when I call load_housing_data() If you're getting an HTTP error, make sure you're running the exact same code as in the notebook (copy/paste it if needed). If the problem persists, please check your network configuration. If it's an SSL error, see the next question. I'm getting an SSL error on MacOSX You probably need to install the SSL certificates (see this StackOverflow question). If you downloaded Python from the official website, then run /Applications/Python\ 3.10/Install\ Certificates.command in a terminal (change 3.10 to whatever version you installed). If you installed Python using MacPorts, run sudo port install curl-ca-bundle in a terminal. I've installed this project locally. How do I update it to the latest version? See INSTALL.md How do I update my Python libraries to the latest versions, when using Anaconda? See INSTALL.md Contributors I would like to thank everyone who contributed to this project, either by providing useful feedback, filing issues or submitting Pull Requests. Special thanks go to Haesun Park and Ian Beauregard who reviewed every notebook and submitted many PRs, including help on some of the exercise solutions. Thanks as well to Steven Bunkley and Ziembla who created the docker directory, and to github user SuperYorio who helped on some exercise solutions. Thanks a lot to Victor Khaustov who submitted plenty of excellent PRs, fixing many errors. And lastly, thanks to Google ML Developer Programs team who supported this work by providing Google Cloud Credit.

Learning Roadmap

Stage 1 — Foundations

Explore the basics of ML concepts; run early notebooks in Google Colab (no setup required).

Stage 2 — Classical ML

Work through Scikit-Learn chapters: data preprocessing, training models, evaluation metrics.

Stage 3 — Neural Networks & Deep Learning

Transition to TensorFlow 2 and Keras — build neural networks, CNNs, RNNs from scratch.

Stage 4 — Advanced Topics

Explore model optimization, custom training loops, deployment, and complete end-to-end project exercises.

Get hands-on — step by step

  1. Open Google Colab (colab.research.google.com) and click the "Open in Colab" badge on the handson-ml3 GitHub README.
  2. Click through the first few Jupyter notebooks (Chapter 1–2) to understand the project structure and run the introductory cells.
  3. Install Anaconda or Miniconda locally — it ships with Python, pip, and package management.
  4. Open a terminal and clone the repository: git clone https://github.com/ageron/handson-ml3.git
  5. Enter the cloned directory (cd handson-ml3) and create the conda environment: conda env create -f environment.yml
  6. Activate it (conda activate homl3) and register the kernel (python -m ipykernel install --user --name=python3)
  7. Launch Jupyter Notebook in that terminal (jupyter notebook) and open Chapter 1's notebook to follow along.
  8. If you have a TensorFlow-compatible GPU, install the NVIDIA CUDA and cuDNN drivers before running deep-learning notebooks.
  9. Work through each chapter sequentially — execute every code cell from top to bottom and experiment with the embedded exercise solutions.
  10. Use Colab for quick lookups without downloads; use your local Jupyter environment when you need to save data, GPU acceleration, or extended work sessions.
