What is it?

py-processors is a Python wrapper for the CLU Lab’s processors NLP library. py-processors relies on processors-server.

Though compatible* with Python 2.x, this library was developed with 3.x in mind.


The server component can be run either via docker or directly with java.

Option 1

Option 2

  • Java 8
  • processor-sever (v3.1.0)
    • this dependency will be retrieved automatically during installation
  • At least 2GB of RAM free for the server (I recommend 3GB+)


py-processors can be installed via pip. The library also has a jupyter extras module which adds widgets/visualizations to juypter notebooks.

basic installation

pip install py-processors

basic + jupyter notebook widgets

pip install py-processors[jupyter]

bleeding edge

pip install git+
