Python client download and overview

This page provides an overview of the H2O eScorer Python client.

Download the Python client​

To download the H2O eScorer Python client wheel, click the Python client tab in the H2O eScorer downloads page. You can then install the downloaded Python client wheel.

The h2o_escorer Python package​

The Python package h2o_escorer provides the Python driver for H2O eScorer. It's a lightweight package with a single class, Client, that provides a simple API with asynchronous functions. These can be used to authenticate and make predictions using models deployed on the H2O AI Cloud.

Authentication​

  • Authenticating h2o_escorer with H2O AI Cloud (HAIC) requires an HAIC platform token. You can get an HAIC platform token from the HAIC UI by clicking CLI & API Access and then clicking the generate token link in the Connect to the platform section. For more information, see Get the platform token.

  • This Python code authenticates with H2O AI Cloud using a platform token and sets up a client to interact with the H2O eScorer service. It uses the TokenProvider to securely manage the token and initializes the Client class for sending asynchronous scoring requests.

    from h2o_authn import TokenProvider
    import getpass 

    print(f"Visit https://internal.dedicated.h2o.ai/auth/get-platform-token to get your platform token") 
    token_provider = TokenProvider(
        refresh_token=getpass.getpass('Enter your platform token: '),
        client_id="hac-platform-public", 
        token_endpoint_url="https://auth.internal.dedicated.h2o.ai/auth/realms/hac/protocol/openid-connect/token" 
    )

    from h2o_escorer import Client
    client = Client(
        escorer_url="https://rest-scorer.internal.dedicated.h2o.ai",
        token_provider=token_provider
    )
