OpenGrm Pynini: Finite-state grammar development in Python
Version 2.1.0 is now available for download.
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.
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
.

PyPI is an
unrelated project; this Pynini can only be installed from source at the moment.
