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)](https://homl.info/er3):
**Note**: If you are looking for the second edition notebooks, check out [ageron/handson-ml2](https://github.com/ageron/handson-ml2). For the first edition, see [ageron/handson-ml](https://github.com/ageron/handson-ml).

* [github.com's notebook viewer](https://github.com/ageron/handson-ml3/blob/main/index.ipynb) 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.
Start by installing [Anaconda](https://www.anaconda.com/products/distribution) (or [Miniconda](https://docs.conda.io/en/latest/miniconda.html)), [git](https://git-scm.com/downloads), and if you have a TensorFlow-compatible GPU, install the [GPU driver](https://www.nvidia.com/Download/index.aspx), 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 `$` signs on each line, they just indicate that these are terminal commands):
I recommend Python 3.8. If you follow the installation instructions above, that's the version you will get. Most code will work with other versions of Python 3, but some libraries do not support Python 3.9 or 3.10 yet, which is why I recommend Python 3.8.
Make sure you call `fetch_housing_data()`*before* you 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.
You probably need to install the SSL certificates (see this [StackOverflow question](https://stackoverflow.com/questions/27835619/urllib-and-ssl-certificate-verify-failed-error)). If you downloaded Python from the official website, then run `/Applications/Python\ 3.8/Install\ Certificates.command` in a terminal (change `3.8` to whatever version you installed). If you installed Python using MacPorts, run `sudo port install curl-ca-bundle` in a terminal.
I would like to thank everyone [who contributed to this project](https://github.com/ageron/handson-ml3/graphs/contributors), 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. And last but not least, thanks a lot to Victor Khaustov who submitted plenty of excellent PRs, fixing many errors.
