Pure Graph of Thoughts

Pure Graph of Thoughts

This is the official implementation of Pure Graph of Thoughts, a new implementation of the Graph of Thoughts concepts.

Graph of Thoughts was originally introduced in the paper Graph of Thoughts: Solving Elaborate Problems with Large Language Models. The official implementation of the paper's proposed API can be found here: https://github.com/spcl/graph-of-thoughts.

The pure_graph_of_thoughts package does not conform the API proposed by the original paper nor is it a fork of it. It aims for a more automation-friendly implementation of the general concept of Graph of Thoughts, where both construction and traversal of a graph can be handled iteratively.

Some key differences and restrictions:

• Operations and thoughts are represented independently of their graph structure.
• As a user-facing API, operations can be defined in a declarative way over a typed and validated data structure (DSL).
• There is a strict distinction between a prompt operation executed by a language model and a code execution operation.
• To simplify parsing logic and to ensure consistent results, the JSON format is used for communication with the language model.
• The scoring is now part of an operation involving a prompt, rather than being a standalone operation that can be added arbitrarily. While this simplifies the automation process, it restricts the user's possibility of adding a validation operation.

Setup Guide

To run this code, Python 3.11 or newer is required. The latest version of the package can be installed from PyPI:

pip install pure-graph-of-thoughts

Alternatively, the package can be installed from source.

Optional Dependencies

The project comes with optional dependencies which are required for some features.

Graph Visualization

To visualize the graphs by using pure_graph_of_thoughts.visualization, the optional visualization dependencies are required.

pip install pure-graph-of-thoughts[visualization]

For a cleaner, hierarchical visualization, add dot-visualization.

pip install pure-graph-of-thoughts[visualization,dot-visualization]

Be aware that dot-visualization requires the GraphViz library to be installed.

pygraphviz on Windows

The Python package pygraphviz (included in dot-visualization) may cause installation problems on Windows. Installing it separately with the following options (including the GraphViz headers) resolves the problem:

python -m pip install --config-settings="--global-option=build_ext" --config-settings="--global-option=-IC:\Program Files\Graphviz\include" --config-settings="--global-option=-LC:\Program Files\Graphviz\lib" pygraphviz

Examples

An example task definition is provided together with a notebook that shows the graph construction and execution. To run the notebook, the optional notebooks dependencies are required.

pip install pure-graph-of-thoughts[notebooks]

Be aware that the examples are not part of the distributed package on PyPI.
