Machine Learning Notebooks

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 second edition of my O'Reilly book Hands-on Machine Learning with Scikit-Learn, Keras and TensorFlow:

Note: If you are looking for the first edition notebooks, check out ageron/handson-ml.

Quick Start

Want to play with these notebooks online without having to install anything?

Use any of the following services.

WARNING: Please be aware that these services provide temporary environments: anything you do will be deleted after a while, so make sure you download any data you care about.

Or open it in Binder:

  • Note: Most of the time, Binder starts up quickly and works great, but when handson-ml2 is updated, Binder creates a new environment from scratch, and this can take quite some time.

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

Browse this repository using's notebook viewer:

Note:'s notebook viewer also works but it is slower and the math equations are not always displayed correctly.

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.

Next, clone this project by opening a terminal and typing the following commands (do not type the first


signs on each line, they just indicate that these are terminal commands):

$ git clone $ cd handson-ml2

If you want to use a GPU, then edit




on Windows) and replace




. Also replace





Next, run the following commands:

$ conda env create -f environment.yml # or environment-windows.yml on Windows $ conda activate tf2 $ python -m ipykernel install --user --name=python3

Then if you're on Windows, run the following command:

$ pip install --no-index -f atari\_py

Finally, start Jupyter:

$ jupyter notebook

If you need further instructions, read the detailed installation instructions.
