Python client for Teradata AnalyticOps Accelerator (AOA)

Project description

Teradata AnalyticOps Client


The aoa is available from pypi

pip install aoa



By default, the CLI looks for configuration stored in ~/.aoa/config.yaml. Copy the config from ModelOps UI -> Session Details -> CLI Config. This will provide the command to create or update the config.yaml. If required, one can override this configuration at runtime by specifying environment variables (see


The cli can be used to perform a number of interactions and guides the user to perform those actions.

> aoa -h
usage: aoa [-h] [--debug] [--version] {list,add,retire,run,init,clone,link,message,connection} ...


optional arguments:
  -h, --help            show this help message and exit
  --debug               Enable debug logging
  --version             Display the version of this tool

  valid actions

    list                List projects, models, local models or datasets
    add                 Add model to working dir
    run                 Train and Evaluate model locally
    init                Initialize model directory with basic structure
    clone               Clone Project Repository
    link                Link repo to Project Repository
    connection          Manage local connections
    feature             Manage feature statistics
    doctor              Diagnose configuration issues


The clone command provides a convenient way to perform a git clone of the repository associated with a given project. The command can be run interactively and will allow you to select the project you wish to clone. Note that by default it clones to the current working directory so you either need to make sure you create an empty folder and run it from within there or else provide the --path argument.

> aoa clone -h
usage: aoa clone [-h] [--debug] [-id PROJECT_ID] [-p PATH]

optional arguments:
  -h, --help            show this help message and exit
  --debug               Enable debug logging
  -id PROJECT_ID, --project-id PROJECT_ID
                        Id of Project to clone
  -p PATH, --path PATH  Path to clone repository to


When you create a git repository, its empty by default. The init command allows you to initialize the repository with the structure required by the AOA. It also adds a default and

> aoa init -h
usage: aoa init [-h] [--debug]

optional arguments:
  -h, --help  show this help message and exit
  --debug     Enable debug logging


Allows to list the aoa resources. In the cases of listing models (pushed / committed) and datasets, it will prompt the user to select a project prior showing the results. In the case of local models, it lists both committed and non-committed models.

> aoa list -h
usage: aoa list [-h] [--debug] [-p] [-m] [-lm] [-t] [-d] [-c]

optional arguments:
  -h, --help           show this help message and exit
  --debug              Enable debug logging
  -p, --projects       List projects
  -m, --models         List registered models (committed / pushed)
  -lm, --local-models  List local models. Includes registered and non-
                       registered (non-committed / non-pushed)
  -t, --templates      List dataset templates
  -d, --datasets       List datasets
  -c, --connections    List local connections

All results are shown in the format

[index] (id of the resource) name

for example:

List of models for project Demo:
[0] (03c9a01f-bd46-4e7c-9a60-4282039094e6) Diabetes Prediction
[1] (74eca506-e967-48f1-92ad-fb217b07e181) IMDB Sentiment Analysis


Add a new model to a given repository based on a model template. A model in any other existing ModelOps git repository (specified via the -t <giturl>) can be used.

> aoa add -h
usage: aoa add [-h] [--debug] -t TEMPLATE_URL -b BRANCH

optional arguments:
  -h, --help            show this help message and exit
  --debug               Enable debug logging
  -t TEMPLATE_URL, --template-url TEMPLATE_URL
                        Git URL for template repository
  -b BRANCH, --branch BRANCH
                        Git branch to pull templates

Example usage

> aoa add -t -b master


The cli can be used to validate the model training and evaluation logic locally before committing to git. This simplifies the development lifecycle and allows you to test and validate many options. It also enables you to avoid creating the dataset definitions in the AOA UI until you are ready and have a finalised version.

> aoa run -h
usage: aoa run [-h] [--debug] [-id MODEL_ID] [-m MODE] [-d DATASET_ID] [-t DATASET_TEMPLATE_ID] [-ld LOCAL_DATASET]

optional arguments:
  -h, --help            show this help message and exit
  --debug               Enable debug logging
  -id MODEL_ID, --model-id MODEL_ID
                        Id of model
  -m MODE, --mode MODE  Mode (train or evaluate)
  -d DATASET_ID, --dataset-id DATASET_ID
                        Remote datasetId
                        Remote datasetTemplateId
  -ld LOCAL_DATASET, --local-dataset LOCAL_DATASET
                        Path to local dataset metadata file
                        Path to local dataset template metadata file
  -c CONNECTION, --connection CONNECTION
                        Local connection id

You can run all of this as a single command or interactively by selecting some optional arguments, or none of them.

For example, if you want to run the cli interactively you just select aoa run but if you wanted to run it non interactively to train a given model with a given datasetId you would expect

> aoa run -id <modelId> -m <mode> -d <datasetId>


The connection credentials stored in the ModelOps service cannot be accessed remotely through the CLI for security reasons. Instead, users can manage connection information locally for the CLI. These connections are used by other CLI commands which access Vantage.

> aoa connection -h
usage: aoa connection [-h] {list,add,remove,export} ...

optional arguments:
  -h, --help         show this help message and exit

  valid actions

    list             List all local connections
    add              Add a local connection
    remove           Remove a local connection
    export           Export a local connection to be used as a shell script


Manage feature metadata by creating and populating feature metadata table(s). The feature metadata tables contain information required when computing statistics during training, scoring etc. This metadata depends on the feature type (categorical or continuous).

As this metadata can contain sensitive profiling information (such as categories), it is recommended to treat this metadata in the same manner as you treat the features for a given use case. That is, the feature metadata should live in a project or use case level database.

> aoa feature -h
usage: aoa feature [-h] {compute-stats,list-stats,create-stats-table,import-stats} ...

optional arguments:
  -h, --help            show this help message and exit

  valid actions

    compute-stats       Compute feature statistics
    list-stats          List available statistics
    create-stats-table  Create statistics table
    import-stats        Import column statistics from local JSON file

aoa feature compute metadata

Compute the feature metadata information required when computing statistics during training, scoring etc. This metadata depends on the feature type (categorical or continuous).

Continuous: the histograms edges Categorical: the categories

> aoa feature compute-stats -h
usage: aoa feature compute-stats [-h] [--debug] -s SOURCE_TABLE -m METADATA_TABLE [-t {continuous,categorical}] -c

optional arguments:
  -h, --help            show this help message and exit
  --debug               Enable debug logging
  -s SOURCE_TABLE, --source-table SOURCE_TABLE
                        Feature source table/view
  -m METADATA_TABLE, --metadata-table METADATA_TABLE
                        Metadata table for feature stats, including database name
  -t {continuous,categorical}, --feature-type {continuous,categorical}
                        Feature type: continuous or categorical
  -c COLUMNS, --columns COLUMNS
                        List of feature columns

Example usage

aoa feature compute-stats \
  -s <feature-db>.<feature-data> \
  -m <feature-metadata-db>.<feature-metadata-table> \
  -t continuous -c numtimesprg,plglcconc,bloodp,skinthick,twohourserins,bmi,dipedfunc,age


A number of authentication methods are supported for both the CLI and SDK.

  • device_code (interactive)
  • client_credentials (service-service)
  • bearer (raw bearer token)

When working interactively, the recommended auth method for the CLI is device_code. It will guide you through the auth automatically. For the SDK, use bearer if working interactively. For both CLI and SDK, if working in an automated service-service manner, use client_credentials.


The SDK for ModelOps allows users to interact with ModelOps APIs from anywhere they can execute python such as notebooks, IDEs etc. It can also be used for devops to automate additional parts of the process and integrate into the wider organization.

Create Client

By default, creating an instance of the AoaClient looks for configuration stored in ~/.aoa/config.yaml. When working with the SDK, we recommend that you specify (and override) all the necessary configuration as part of the AoaClient invocation.

An example to create a client using a bearer token for a given project is

from aoa import AoaClient

client = AoaClient(

To get the values to use for bearer token and aoa_url, go to the ModelOps UI -> Session Details -> SDK Config.

Read Entities

We provide an extensive sdk implementation to interact with the APIs. You can find, create, update, archive, etc any entity that supports it via the SDK. In addition, most if not all search endpoints are also implemented in the sdk. Here are some examples

from aoa import AoaClient, DatasetApi, JobApi
import pprint

client = AoaClient(project_id="23e1df4b-b630-47a1-ab80-7ad5385fcd8d")

dataset_api = DatasetApi(aoa_client=client)

datasets = dataset_api.find_all()

dataset = dataset_api.find_by_id("11e1df4b-b630-47a1-ab80-7ad5385fcd8c")

job_api = JobApi(aoa_client=client)
jobs = job_api.find_by_id("21e1df4b-b630-47a1-ab80-7ad5385fcd1c")

Deploy Model Version

Let's assume we have a model version 4131df4b-b630-47a1-ab80-7ad5385fcd15 which we want to deploy In-Vantage and schedule it to execute once a month at midnight of the first day of the month using dataset connection 11e1df4b-b630-47a1-ab80-7ad5385fcd8c and dataset template d8a35d98-21ce-47d0-b9f2-00d355777de1. We can use the SDK as follows to perform this.

from aoa import AoaClient, TrainedModelApi, JobApi

client = AoaClient(project_id="23e1df4b-b630-47a1-ab80-7ad5385fcd8d")
trained_model_api = TrainedModelApi(aoa_client=client)
job_api = JobApi(aoa_client=client)

trained_model_id = "4131df4b-b630-47a1-ab80-7ad5385fcd15"
deploy_request = {
   "engineType": "IN_VANTAGE",
   "publishOnly": False,
   "language": "PMML",
   "cron": "0 0 1 * *",
   "byomModelLocation": {
     "database": "<db-name>",
     "table": "<table-name>"
    "datasetConnectionId": "11e1df4b-b630-47a1-ab80-7ad5385fcd8c",
    "datasetTemplateId": "d8a35d98-21ce-47d0-b9f2-00d355777de1",
    "engineTypeConfig": {
        "dockerImage": "",
        "engine": "byom",
        "resources": {
            "memory": "1G",
            "cpu": "1"

job = trained_model_api.deploy(trained_model_id, deploy_request)

# wait until the job completes (if the job fails it will raise an exception)

Import Model Version

Let's assume we have a PMML model which we have trained in another data science platform. We want to import the artefacts for this version (model.pmml and data_stats.json) against a BYOM model f937b5d8-02c6-5150-80c7-1e4ff07fea31.

from aoa import (
import uuid

client = AoaClient(project_id="23e1df4b-b630-47a1-ab80-7ad5385fcd8d")
model_api = ModelApi(aoa_client=client)
trained_model_api = TrainedModelApi(aoa_client=client)
trained_model_artefacts_api = TrainedModelArtefactsApi(aoa_client=client)
job_api = JobApi(aoa_client=client)

artefacts_import_id = uuid.uuid4()
artefacts = ["model.pmml", "data_stats.json"]

# first, upload the artefacts which we want to associate with the BYOM model version
trained_model_artefacts_api.upload_artefacts(artefacts_import_id, artefacts)

import_request = {
   "artefactImportId": str(artefacts_import_id),
   "externalId": "my-byom-version-id"

# update with id of your model 
model_id = "<model-uuid>"

job = model_api.import_byom(model_id, import_request)

# wait until the job completes (if the job fails it will raise an exception)

# now you can list the artefacts which were uploaded and linked to the model version
trained_model_id = job["metadata"]["trainedModel"]["id"]
artefacts = trained_model_artefacts_api.list_artefacts(trained_model_id)
