ModelOps - Import and Deploy your first BYOM Model

Author: Pablo Escobar de la Oliva
Last updated: May 29th, 2023

Overview

This is a how-to for people who are new to ClearScape Analytics ModelOps. In the tutorial, you will be able to create a new project in ModelOps, upload the required data to Vantage, and track the full lifecycle of an imported Diabetes demo model using BYOM mechanisms.

Prerequisites

  • Access to a Teradata Vantage instance with ClearScape Analytics (includes ModelOps)

  • Ability to run Jupyter notebooks

If you need a test instance of Vantage, you can provision one for free at https://clearscape.teradata.com.

Files needed

Let’s start by downloading the needed files for this tutorial. Download these 4 attachments and upload them in your Notebook filesystem. Select the files depending on your version of ModelOps:

ModelOps version 6 (October 2022):

Alternatively you can git clone following repos

git clone https://github.com/willfleury/modelops-getting-started
git clone https://github.com/Teradata/modelops-demo-models/

ModelOps version 7 (April 2023):

git clone -b v7 https://github.com/willfleury/modelops-getting-started.git
git clone https://github.com/Teradata/modelops-demo-models/

Setting up the Database and Jupyter environment

Follow the ModelOps_Training Jupyter Notebook to setup the database, tables and libraries needed for the demo.

Understand where we are in the Methodology

Create a new Project or use an existing one

Add a new Project

Here you can test the git connection. If is green then save and continue. Skip the service connection settings for now.

When creating a new project, ModelOps will ask you for a new connection.

Create a Personal Connection

Personal connection

  • Name: Vantage personal your-name

  • Description: Vantage demo env

  • Host: tdprd.td.teradata.com (internal for teradata transcend only)

  • Database: your-db

  • VAL Database: TRNG_XSP (internal for teradata transcend only)

  • BYOM Database: TRNG_BYOM (internal for teradata transcend only)

  • Login Mech: TDNEGO

  • Username/Password

Validate permissions in SQL database for VAL and BYOM

You can check the permissions with the new healthcheck panel in the connections panel

Add dataset to identify Vantage tables for BYOM evaluation and scoring

Let’s create a new dataset template, then 1 dataset for training and 2 datasets for evaluation so we can monitor model quality metrics with 2 different datasets

Add datasets

  • create dataset template

  • Catalog

  • Name: PIMA

  • Description: PIMA Diabetes

  • Feature Catalog: Vantage

  • Database: your-db

  • Table: aoa_feature_metadata

Features Query:

SELECT * FROM {your-db}.pima_patient_features

Entity Key: PatientId Features: NumTimesPrg, PlGlcConc, BloodP, SkinThick, TwoHourSerIns, BMI, DiPedFunc, Age

Entity & Target Query:

SELECT * FROM {your-db}.pima_patient_diagnoses

Entity Key: PatientId Target: HasDiabetes

Predictions

  • Database: your-db

  • Table: pima_patient_predictions

Entity selection:

Query:

SELECT * FROM pima_patient_features WHERE patientid MOD 5 = 0

Only for v6 (in v7 you will define this in the BYOM no code screen): BYOM Target Column: CAST(CAST(json_report AS JSON).JSONExtractValue('$.predicted_HasDiabetes') AS INT)

Create training dataset

Basic

  • Name: Train

  • Description: Training dataset

  • Scope: Training

  • Entity & Target

Query:

SELECT * FROM {your-db}.pima_patient_diagnoses WHERE patientid MOD 5 = 1

Create evaluation dataset 1

Basic

  • Name: Evaluate

  • Description: Evaluation dataset

  • Scope: Evaluation

  • Entity & Target

Query:

SELECT * FROM {your-db}.pima_patient_diagnoses WHERE patientid MOD 5 = 2

Create evaluation dataset 2

Basic

  • Name: Evaluate

  • Description: Evaluation dataset

  • Scope: Evaluation

  • Entity & Target

Query:

SELECT * FROM {your-db}.pima_patient_diagnoses WHERE patientid MOD 5 = 3

Model Lifecycle for a new BYOM

Download and unzip the files needed, links are at the top of the tutorial. For PMML file you can also download a PMML generated in the training of a GIT model.

  • BYOM.ipynb

  • model.pmml

  • requirements.txt

  • evaluation.py

  • data_stats.json

  • init.py

Define BYOM Model with Evaluation and Monitoring

  • Import Version

  • for v7 - BYOM no code is available - You can enable automated evaluation and data drift monitoring. In Monitoring page use BYOM Target Column: CAST(CAST(json_report AS JSON).JSONExtractValue('$.predicted_HasDiabetes') AS INT)

  • Evaluate

  • Review evaluation report, including dataset statistics

  • Approve

  • Deploy in Vantage - Engine, Publish, Schedule. Scoring dataset is required Use your connection and select a database. e.g "aoa_byom_models"

  • Deployments/executions

  • Evaluate again with dataset2 - to monitor model metrics behavior

  • Monitor Model Drift - Data and Metrics

  • for v7 - Review your predictions directly from Deployments → Job page

  • Open BYOM notebook to execute the PMML predict from SQL code

  • Retire

Summary

In this quick start we have learned how to follow a full lifecycle of BYOM models into ModelOps and how to deploy it into Vantage. Then how we can schedule a batch scoring or test restful or on-demand scorings and start monitoring on Data Drift and Model Quality metrics.
