Python 3 code to reproduce the figures in the books Probabilistic Machine Learning: An Introduction (aka "book 1") and Probabilistic Machine Learning: Advanced Topics (aka "book 2"). The code uses the standard Python libraries, such as numpy, scipy, matplotlib, sklearn, etc. Some of the code (especially in book 2) also uses JAX, and in some parts of book 1, we also use Tensorflow 2 and a little bit of Torch. See also probml-utils for some utility code that is shared across multiple notebooks.
For the latest status of the code, see Book 1 dashboard and Book 2 dashboard. As of September 2022, this code is now in maintenance mode.
The notebooks needed to make all the figures are available at the following locations.
- All notebooks (sorted by filename)
- Book 1 notebooks (sorted by chaper)
- Book 2 notebooks (sorted by chapter).
Colab has most of the libraries you will need (e.g., scikit-learn, JAX) pre-installed, and gives you access to a free GPU and TPU. We have a created a
colab intro
notebook with more details. To run the notebooks on colab in any browser, you can go to a particular notebook on GitHub and change the domain from github.com to githubtocolab.com as suggested here. If you are using Google Chrome browser, you can use "Open in Colab" Chrome extension to do the same with a single click.
We assume you have already installed JAX and Tensorflow and Torch, since the details on how to do this depend on whether you have a CPU, GPU, etc.
You can use any of the following options to install the other requirements.
- Option 1
pip install -r https://raw.githubusercontent.com/probml/pyprobml/master/requirements.txt- Option 2
Download requirements.txt locally to your path and run
pip install -r requirements.txtWhen you want more power or control than colab gives you, you should get a Google Cloud Platform (GCP) account (or you can use some other cloud provider, like Paperspace) to get a virtual machine with GPUs or TPUs. You can then use this as a virtual desktop which you can access via ssh from inside VScode. We have created a short tutorial on Colab, GCP and TPUs with more information.
