Pynini: Finite-state grammar development in Python

Red led Version 2.1.6 is now available for download.

Radioactive Pynini is now available on conda-forge. Users users who already have Conda can install Pynini and all dependencies using the following command: conda install -c conda-forge pynini

First class Pynini can now be used from a Colab notebook, as shown here. Add the following to the top of your notebook: !pip install --only-binary :all: pynini

Strategy When using Pynini from a Colab notebook, logging and error messages sent to standard error are lost. To recover them, install wurlitzer (e.g., !pip install wurlitzer) and then add the following at the top of your notebook: %load_ext wurlitzer

OpenGrm Pynini, like Thrax, compiles grammars expressed as strings, regular expressions, and context-dependent rewrite rules into weighted finite-state transducers. It uses the OpenFst library and its Python extension to create, access and manipulate compiled grammars. Pynini is embedded in a Python module, allowing users to write Thrax-like grammars using Python's flexible syntax (including imperative programming constructs not available in Thrax) and powerful toolchain.

It is (loosely) named after Pāṇini (पाणिनि), the renowned Sanskrit grammarian.
