OpenGrm Pynini: Finite-state grammar development in Python


Red led Version 2.1.2 is now available for download.
NEW Pynini is now available on conda-forge. Linux (x86) and Mac OS X users who already have Conda can install Pynini and all dependencies using the following command: conda install -c conda-forge pynini.
Strategy When using Pynini from a Jupyter or Colab notebook, logging and error messages sent to STDERR are lost. To recover them, install wurlitzer and then add the following to 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, including an interactive development ("REPL") environment.

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