OpenGrm Pynini: Finite-state grammar development in Python
Version 2.1.4 is now available for download.
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
.
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.
