Pynini: Finite-state grammar development in Python
Version 2.1.6.post1 is now available for download.

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

Pynini can now be used from a
Colab
notebook; see
here
for an example.
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.
