memo-lang 0.1.2

A language for mental models

memo

memo is a new probabilistic programming language for expressing computational cognitive models involving sophisticated recursive reasoning, and for performing fast enumerative inference on such models. memo inherits from the tradition of WebPPL-based Bayesian modeling (see probmods, agentmodels, and problang), but aims to make models easier to write and run by taking advantage of modern programming language techniques and hardware capabilities.

Installing memo

1. memo is based on Python. Before installing memo, make sure you have Python 3.12 or higher installed. You can check this by running python --version. (As of writing, Python 3.12 is the latest version of Python, and memo depends on several of its powerful new features.)
2. Next, install JAX, a Python module that memo uses to produce fast, differentiable, GPU-enabled code. If you don't have a GPU, then running pip install jax should be enough. Otherwise, please consult the JAX website for installation instructions. You can check if JAX is installed by running import jax in Python.
3. Finally, install memo by running pip install memo-lang. You can check if memo is installed by running from memo import memo in Python.
