Examples

In this example, if a WML instance already exists it is used, but if not a new Lite plan instance is provisioned and used. If an OpenScale instance exists, its datamart is dropped and recreated along with its datamart internal database schema. Otherwise, a Lite plan OpenScale instance is provisioned. The GermanCreditRiskModel is stored and deployed in WML, configured to OpenScale, and 7 days' historical data stored. Then new feedback data is uploaded, 100 new live scoring predictions are made, followed by fairness and quality checks, and one explanation.

export APIKEY=<IBM_CLOUD_API_KEY>
ibm-ai-openscale-cli --apikey $APIKEY

In this example, assume the user already has provisioned instances of WML, OpenScale, IBM Cloud Database for Postgres (ICD), and has selected a schema for the OpenScale datamart database. The OpenScale datamart is dropped and recreated, and the datamart's database schema is dropped and recreated. An already-deployed instance of the DrugSelectionModel is configured to OpenScale, and 7 days' historical data stored, followed by new feedback data upload, 100 new scores, fairness and quality checks, and one explanation.

export APIKEY=<IBM_CLOUD_API_KEY>
export WML=<path to WML instance credentials JSON file>
export ICD=<path to ICD instance credentials JSON file>
export SCHEMA=<ICD database schema name>
ibm-ai-openscale-cli --apikey $APIKEY --wml $WML --model DrugSelectionModel --deployment-name DrugSelectionModelDeployment --icd $ICD --datamart-name $SCHEMA

In this example, assume the user already has provisioned an Entry plan instance of IBM DB2 Warehouse on Cloud. The OpenScale datamart's tables within the user's existing DB2 schema are dropped and recreated. The GermanCreditRiskModel is stored and deployed in WML, configured to OpenScale, and 7 days' historical data stored, followed by new feedback data upload, 100 new scores, fairness and quality checks, and one explanation.

export APIKEY=<IBM_CLOUD_API_KEY>
export DB2=<path to DB2 instance credentials JSON file>
export SCHEMA=<user's DB2 database schema>
ibm-ai-openscale-cli --apikey $APIKEY --db2 $DB2 --datamart-name $SCHEMA --keep-schema

In this example, assume the user has their own custom model named MyBusinessModel stored in WML and deployed as MyBusinessModelDeployment. Also assume they already have a provisioned instance of OpenScale which has not yet been configured. In the custom model directory, the user has provided a configuration.json file with the required model configuration details. The OpenScale datamart and datamart database schema are created, and the MyBusinessModelDeployment is configured to OpenScale. Then new feedback data is uploaded (if provided), 100 new scoring requests are made to the model, followed by fairness and quality checks (if configured), and one explanation.

export APIKEY=<IBM_CLOUD_API_KEY>
export WML=<path to WML instance credentials JSON file>
export MODELPATH=<path to custom model directory>
ibm-ai-openscale-cli --apikey $APIKEY --wml $WML --custom-model MyBusinessModel --deployment-name MyBusinessModelDeployment --custom-model-directory $MODELPATH

FAQ

Q: What is the GermanCreditRiskModel sample model?

A. The GermanCreditRiskModel sample model is taken from the "Watson Studio, Watson Machine Learning and Watson OpenScale samples" GitHub repo, specifically the IBM Watson OpenScale tutorials. When you run ibm-ai-openscale-cli to deploy and configure the GermanCreditRiskModel, the result will be as if you had run the tutorial notebook appropriate for your machine learning engine.

Q: What are the formats for the credentials files?

A: Each credential file has its own format:

Postgres

{
  "uri": "postgres://<USERNAME>:<PASSWORD>@<HOSTNAME>:<PORT>/<DB>"
}

IBM Cloud Database for Postgres(ICD)

  • Copy the Service Credentials from your ICD service instance in IBM Cloud

DB2

{
    "username": "<USERNAME>",
    "password": "<PASSWORD>",
    "hostname": "<HOSTNAME>",
    "port": "<PORT>",
    "db": "<DB>"
}

IBM Watson Machine Learning (WML)

  • Copy the Service Credentials from your WML service instance in IBM Cloud

Microsoft Azure

{
    "client_id": "<CLIENT_ID>",
    "client_secret": "<CLIENT_SECRET",
    "tenant": "<TENANT>",
    "subscription_id": "<SUBSCRIPTION_ID>"
}

SPSS

{
    "username": "<USERNAME>",
    "password": "<PASSWORD",
    "url": "<URL>"
}

Custom engine

{
    "url": "<URL>"
}

Amazon Web Services Sagemaker (AWS)

{
    "access_key_id": "<ACCESS_KEY_ID>",
    "secret_access_key": "<SECRET_ACCESS_KEY>",
    "region": "<REGION>"
}

Q: How do the reset options work?

A: The reset options each affect a different level of data in the datamart:

  • --reset metrics : Clean up the payload logging table, monitoring history tables etc, so that it restores the system to a fresh state with datamart configured, model deployments added, all monitors configured, but no actual metrics in the system yet. The system is ready to go. Not supported for Watson OpenScale internal databases.
  • --reset monitors : Remove all configured monitors and corresponding metrics and history, but leave the actual model deployments (if any) in the datamart. User can proceed to configure the monitors via user interface, API, or ibm-ai-openscale-cli.
  • --reset datamart : "Factory reset" the datamart to a fresh state as if there was not any configuration.
  • --reset model : Delete the sample models and deployments from WML. Not yet supported for non-WML engines. Does not affect the datamart.
  • --reset all : Reset both the datamart and sample models.

Q: Can I use SSL for connecting to the datamart DB2 database?

A: Yes. The below options can be used for connecting to a DB2 with SSL:

  1. DB2 Warehouse on Cloud databases automatically support SSL, using the VCAP json file generated on the "Service Credentials" page.
  2. For on-prem or ICP4D DB2 databases:
    1. You can specify the path on the local client machine to a copy of the DB2 server's SSL certificate "arm" file, using an "ssldsn" connection string in the VCAP json file:
    {
      "hostname": "<ipaddr>",
      "username": "<uid>",
      "password": "<pw>",
      "port": 50000,
      "db": "<dbname>",
      "ssldsn": "DATABASE=<dbname>;HOSTNAME=<ipaddr>;PORT=50001;PROTOCOL=TCPIP;UID=<uid>;PWD=<pw>;Security=ssl;SSLServerCertificate=/path_on_local_client_machine_to/db2server_instance.arm;"
    }
    
    1. You can specify the base64-encoded certificate as the certificate_base64 attribute directly in the credentials along with a ssl attribute set to true, as below:
    {
      "hostname": "<ipaddr>",
      "username": "<uid>",
      "password": "<pw>",
      "port": 50000,
      "db": "<dbname>",
      "ssl": true,
      "certificate_base64":"Base64 encoded SSL certificate"
    }
    

If SSL connections are not needed, or not configured on the DB2 server, you can remove the "ssldsn" tag and ibm-ai-openscale-cli will use the non-SSL "dsn" tag instead. If the VCAP has both dsn and ssldsn tags, ibm-ai-openscale-cli will use "ssldsn" tag to create an SSL connection.

Q: What are the contents of a custom model directory?

A: These files are used to configure a custom model to IBM Watson OpenScale:

Required

  • configuration.json: the model configuration details

Optional

  • model_content.gzip: exported model file from WML, to be loaded and deployed into WML if --deployment-name is not specified
  • model_meta.json: exported model metadata from WML (required if model gzip is provided)
  • pipeline_content.gzip: exported model pipeline file from WML, to be loaded and deployed into WML if --deployment-name is not specified
  • pipeline_meta.json: exported model pipeline metadata from WML (required if pipeline gzip is provided)
  • drift_model.gzip: exported model file from WML for a trained Drift model (required if drift configuration provided in configuration.json)

Syntax of configuration.json

A JSON file that specifies the OpenScale configuration for the model. The key components are:

  • asset_metadata (required): top-level model specification elements
  • training_data_reference (required): reference to the model training data csv in COS
  • training_data_type (optional): required if there are any numeric-valued model features
  • quality_configuration (optional): if applicable for the model
  • fairness_configuration (optional): if applicable for the model
  • drift_configuration (optional): if applicable for the model

Valid values for parameters in asset_metadata:

  • problem_type: REGRESSION, BINARY_CLASSIFICATION, MULTICLASS_CLASSIFICATION
  • input_data_type: STRUCTURED

Here is an example:

{
    "asset_metadata": {
        "problem_type": "BINARY_CLASSIFICATION",
        "input_data_type": "STRUCTURED",
        "label_column": "Risk",
        "prediction_column": "Scored Labels",
        "probability_column": "Scored Probabilities",
        "categorical_columns": [ "CheckingStatus" ],
        "feature_columns": [ "CheckingStatus", "LoanDuration", "Age" ]
    },
    "training_data_reference": {
        "credentials" : {<IBM Cloud COS credentials>},
        "path" : "<path within COS to training data csv file (bucket name + / + filename)>",
        "firstlineheader": "True"
    },
    "training_data_type": { "LoanDuration": "int", "Age": "int" },
    "quality_configuration": { "threshold": 0.95, "min_records": 40 },
    "fairness_configuration": {
        "features": [
            {
                "feature": "Age",
                "majority": [[ 26, 75 ]],
                "minority": [[ 18, 25 ]],
                "threshold": 0.98
            }
        ],
        "favourable_classes": [ "No Risk" ],
        "unfavourable_classes": [ "Risk" ],
        "min_records": 100
    },
    "drift_configuration": {
        "threshold": 0.15,
        "min_records": 100
    }
}

Syntax of training_data.csv

A CSV file of the data used to train the model. This data is also used by live scoring requests to the model using the range of actual values for each feature from the training data. A header row is required, with column names that match the model's feature names. Any column with numeric values must be included in the training_data_type specification in the configuration.json. A typical example:

CheckingStatus,LoanDuration,Age,Risk
no_checking,28,30,Risk
0_to_200,28,27,No Risk
