Hands-On Machine Learning with Scikit-Learn and PyTorch

The goal of this project is to teach you the fundamentals of Machine Learning in Python. It contains the example code and solutions to the exercises in the first edition of my new O'Reilly book Hands-on Machine Learning with Scikit-Learn and PyTorch (1st edition):

Note: If you are looking for the notebooks for the TensorFlow/Keras version of this book, check out ageron/handson-ml3.

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.

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 install this project on your own machine?

FAQ

Which Python version should I use?

I recommend Python 3.12. If you follow the installation instructions above, that's the version you will get. Versions 3.10 and 3.11 should work as well, but some libraries are not yet available for 3.13.

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\ 3.12/Install\ Certificates.command in a terminal (change 3.12 to whatever version you installed). If you installed Python using MacPorts, run sudo port install curl-ca-bundle in a terminal.
