FlipPy probabilistic programming language

FlipPy: Pythonic Probabilistic Programming

FlipPy lets you specify probabilistic programs in Python syntax while seamlessly interacting with the rest of Python.

Documentation and tutorials can be found here.

Quick start

FlipPy can be installed with pip:

pip install flippy-lang

The core functionality of FlipPy does not require any dependendencies, so the above command will only install FlipPy. To install the dependencies required for full functionality, use:

pip install flippy-lang[full]

Example: Sum of Bernoullis

FlipPy lets you specify probablistic programs using standard Python syntax. Here is a simple example involving the sum of two Bernoulli random variables:

from flippy import infer, flip

@infer
def fn():
    x = flip(0.5)
    y = flip(0.5)
    return x + y

fn() # Distribution({0: 0.25, 1: 0.5, 2: 0.25})

Tests

To run the tests (this requires installing pytest):

(venv) $ pytest
