Welcome to the world of probabilistic programming! In this guide, we’ll explore how to install and run Pyro, a flexible and scalable deep probabilistic programming library built on PyTorch. If you’re ready to dive into the ocean of data and models, read on!

What is Pyro?

Pyro is a universal probabilistic programming language (PPL) designed to represent any computable probability distribution. Developed at Uber AI and now maintained by community contributors, including the Broad Institute, Pyro excels at handling large datasets while being easy to use and maintain. It combines automation with the flexibility to customize when you need it the most.

Installing Pyro

Installing a Stable Release

To get started with Pyro, you can easily install it using pip. Here are the steps:

• Install using pip:

pip install pyro-ppl

• Install from source:

git clone git@github.com:pyro-ppl/pyro.git
cd pyro
git checkout master  # master is pinned to the latest release
pip install .

• Install with extra packages:

Run the following command to install required dependencies:

pip install pyro-ppl[extras]

Ensure that the models come from the same release version of the Pyro source code as you have installed.

Installing Pyro Dev Branch

If you want to access recent features, here’s how to install the dev branch:

• Install Pyro using pip:

pip install git+https://github.com/pyro-ppl/pyro.git

• With extras to run example models:

pip install git+https://github.com/pyro-ppl/pyro.git#egg=project[extras]

• Install from source:

git clone https://github.com/pyro-ppl/pyro
cd pyro
pip install .  # pip install .[extras] for running models in examples/tutorials

Running Pyro from a Docker Container

If you prefer a more isolated environment, you can run Pyro in a Docker container. For details, refer to the instructions here.

Troubleshooting

If you encounter any issues during installation or usage, please consider the following troubleshooting tips:

• Ensure you have the latest version of pip installed.
• Check if you cloned the correct branch of the Pyro repository.
• If you received an error related to dependencies, try running the installation commands again, ensuring the extras are included.

Analogy: Imagine Building with Legos

Think of Pyro as a versatile Lego set. Each brick represents a probability distribution, and just like Legos, you can connect and combine these blocks to create complex structures (models). When you install Pyro, it’s like laying out all your Legos perfectly sorted by color and size, allowing you to build efficiently. The smaller brick pieces (core abstractions) give you flexibility in how you construct your models, while the larger pieces (high-level abstractions) provide broad canvases for creativity. Just as you can add new bricks to your Lego collection, Pyro allows you to incorporate additional packages and features as your project grows.

Now you are ready to embark on your journey with Pyro. Happy programming!
