TigerGraph’s Machine Learning Workbench is a Python-based toolkit that accelerates the development of graph-enhanced machine learning, which leverages the added insight from connected data and graph features for better predictions. The GitHub repository of the notebooks are found here.

To access the graph database through pyTigerGraph, we need to create a database username and password, then put these credentials in config.json.

1. Go back to your browser tab/window for TigerGraph Cloud.
2. Click on Cluster on the left side menu. For the cluster containing this workbench, click Access Management.
3. Create a database user and grant appropriate permissions (e.g., globaldesigner). More details about managing database users can be found here: https://docs.tigergraph.com/cloud/security/manage-db-users. More details about access control settings can be found here: https://docs.tigergraph.com/tigergraph-server/current/user-access/access-control-model#_built_in_roles.

1. After creating the login credentials in Step 1, go back to the ML Workbench and edit config.json in the root jupyter notebook folder to replace the host, username and password with your new credentials. Example: config.json

{
    "host": "https://subdomain.i.tgcloud.io",
    "username": "user_1",
    "password": "MyPassword1!",
    "getToken": true 
}

Note: For the host parameter, it is the domain name of the Cluster. You can find it in Cluster’s Details page which can be found by clicking on Clusters on tgCloud's left panel, then by clicking on the cluster’s name in the list (Details -> Network Information -> Domain). Replace the substring subdomain with your actual subdomain. Make sure to keep the “https://” at the beginning of the domain in the json config.

2. Once the credentials are updated, all the example notebooks and demos will refer to this config for database connections via pyTigerGraph. For example, here is how the algos/centrality.ipynb notebook connects to the database:

from pyTigerGraph import TigerGraphConnection
conn = TigerGraphConnection(
    host=config["host"],
    username=config["username"],
    password=config["password"]
)

The ML Workbench comes with a collection of canonical Python notebooks that will introduce you to a number of features of the TigerGraph ML ecosystem.

• The basics directory contains notebooks on how to get started with pyTigerGraph.
• The algos directory contains notebooks for each category of algorithms within TigerGraph's Graph Data Science Library. You can run these algorithms via the pyTigerGraph Featurizer functionality.
• The GNNs directory contains tutorial notebooks on how to train GNNs using data stored in a TigerGraph database.
• The applications directory contains end to end demos of common applications such as fraud detection and recommendation.

We recommend starting with the tutorials in the basics folders if you are new to pyTigerGraph. Once you are familiar with our pyTigerGraph client, familiarize yourself with a few graph algorithms with the examples in the algos folder before going through the GNNs and end-to-end applications tutorials.
