lambeq is a toolkit for quantum natural language processing (QNLP).


Getting started


  • Python 3.7+


Direct pip install

The base lambeq can be installed with the command:

pip install lambeq

This does not include optional dependencies such as depccg and PyTorch, which have to be installed separately. In particular, depccg is required for lambeq.ccg2discocat.DepCCGParser.

To install lambeq with depccg, run instead:

pip install cython numpy
pip install lambeq[depccg]
depccg_en download

See below for further options.

Automatic installation (recommended)

This runs an interactive installer to help pick the installation destination and configuration.

  1. Run:
    <div class="highlight highlight-source-shell position-relative overflow-auto" data-snippet-clipboard-copy-content="bash

    bash <(curl '')
