tinygraphio 1.0.0

The tinygraphio graph data interchange file format

tinygraphio

Python implementation of the tinygraphio graph data interchange file format.

Installation

Install with poetry

poetry add tinygraphio

Install with pip

pip install tinygraphio

Usage

• The Tinygraph class implements a compressed sparse row graph
• The TinygraphioReader implements reading a graph from a binary file-like object
• The TinygraphioWriter implements writing a graph to a binary file-like object

from tinygraphio.graph import Tinygraph, Node, Edge
from tinygraphio.reader import TinygraphioReader
from tinygraphio.writer import TinygraphioWriter

Writing

graph = Tinygraph(offsets=[0, 2, 4, 5], targets=[1, 2, 0, 2, 1])

with open("berlin.tinygraph", "wb") as f:
    writer = TinygraphioWriter(f)
    writer.write(graph)

Reading

with open("berlin.tinygraph", "rb") as f:
    reader = TinygraphioReader(f)
    graph = reader.read()

Note: this library implements reading and writing a compressed sparse row graph in a The use case tinygraphio covers is storing large graphs effectively and efficiently and sharing graphs in a portable way. We do not provide a full-blown graph computation toolkit on purpose.
