A Python wrapper API for operating and working with the Neo4j Graph Data Science (GDS) library

Overview

gdsclient

NOTE: This is a work in progress and many GDS features are known to be missing or not working properly.

This repo hosts the sources for gdsclient, a Python wrapper API for operating and working with the Neo4j Graph Data Science (GDS) library. gdsclient enables users to write pure Python code to project graphs, run algorithms, and define and use machine learning pipelines in GDS. The API is designed to mimic the GDS Cypher procedure API, but in Python code. It abstracts the necessary operation of the Neo4j Python Driver to offer a simpler surface.

Please leave any feedback as issues on this repository. Happy coding!

Installation

To build and install gdsclient from this repository, simply run the following command:

pip3 install .

Documentation

A minimal example of using gdsclient to connect to a Neo4j database and run GDS algorithms:

from neo4j import GraphDatabase
from gdsclient import Neo4jQueryRunner, GraphDataScience

# Set up driver and gds module
URI = "bolt://localhost:7687" # Override according to your setup
driver = GraphDatabase.driver(URI) # You might also have auth set up in your db
runner = Neo4jQueryRunner(driver)
gds = GraphDataScience(runner)

# Project your graph
graph = gds.graph.create("graph", "*", "*")

# Run the PageRank algorithm with custom configuration
gds.pageRank.write(graph, tolerance=0.5, writeProperty="pagerank")

For extensive documentation of all operations supported by GDS, please refer to the GDS Manual.

Extensive end-to-end examples in Jupyter ready-to-run notebooks can be found in the examples directory:

  • streamNodeProperty() doesn't work with gds.run_cypher() as I guess

    streamNodeProperty() doesn't work with gds.run_cypher() as I guess

    graphdatascience 1.3

    I tried a query like this:

    query = f'''
   call gds.graph.streamNodeProperty(
      'xxx',
      'xxxx',
      ['xxxxx']
   )
yield nodeId as id, propertyValue as degree
return id, degree limit 100
...
result = gds.run_cypher(query)

    => KeyError: 'graph_name'

    I figured out to make it work like this:

    query = f'''
   ...
'''
params = {
   'graph_name': 'xxx',
   'properties': 'xxxx',
   'entities'" ['xxxxx'],
   'config': ''
}
result = gds.run_cypher(query, params)

    => No error, but it returned all rows(not limited to 100) as nodeId and propertyValue(not renamed as id and degree)

    Other cypher queries works with gds.run_cypher(query) as expected.

  • gds.degree.stream not respecting orientation?

    gds.degree.stream not respecting orientation?

    Describe the bug I'm trying to reproduce a similar result that I would get in GDS.

    To Reproduce Cypher code:

    call gds.graph.project('xdc-test-search', ['Event','Search'], { HAS_SEARCH:{orientation:'REVERSE'}})
call gds.degree.stream('xdc-test-search')
YIELD nodeId, score
return gds.util.asNode(nodeId).search_name_1 as SearchTerm, score As NumberOfSearches
Order by NumberOfSearches Descending, SearchTerm Limit 10;

    The above returns the Search nodes.

    Python code:

    node_projection = ["Event","Search"]
relationship_projection = {"HAS_SEARCH": {"orientation": "REVERSE"}}
G, _ = gds.graph.project("xdc-test-search", node_projection, relationship_projection)
degree_stream = gds.degree.stream(G)

    degree.stream above is returning the node ids of the Event nodes (other side of direction), even if I were to use G = gds.graph.get("xdc-test-search") and use the projection created with cypher.

    I'm sure it's something I'm doing on my end :)

    graphdatascience library version: 1.3 GDS plugin version: 2.1.7 Python version: 3.9.12 Neo4j version: 4.4.10 Operating system: macOS 12.6

    The image below is what I would expect from the python approach. image

    Relationship Orientation during graph construction with dataframes

    Hi, I'd like to understand if it is possible to construct a graph from data frames without orientation so that I can have an undirected relationship. I see from the schema here https://neo4j.com/docs/graph-data-science/current/graph-project-apache-arrow/#arrow-send-relationships that source and destination are mandatory but there is no special column for orientation.

I would like to set the database I plan to use upon initializing my gds object GraphDataScience(URI, auth=creds, database='my-db') rather than having to call gds.set_database("my-db"). This would purely be a simple convenience to save a line of code.
