Dataiku DSSInstall

Overview

This node integrates with the Dataiku DSS API, enabling users to perform a wide range of operations on various Dataiku DSS resources. Specifically for the Model Comparison resource and the List Model Comparisons operation, it retrieves a list of model comparisons within a specified project.

Common scenarios where this node is beneficial include:

• Automating retrieval of model comparison data for monitoring or reporting.
• Integrating model comparison results into workflows for further analysis or decision-making.
• Managing and auditing machine learning models by accessing their comparison metadata programmatically.

Example use case:

• A data scientist wants to fetch all model comparisons in a project to analyze performance differences between models automatically as part of a CI/CD pipeline.

Properties

Output

The output is a JSON array where each item represents a model comparison object retrieved from the Dataiku DSS API under the specified project. The exact structure of each model comparison object depends on the Dataiku DSS API response but typically includes details such as comparison ID, involved models, metrics, timestamps, and status.

No binary data output is associated with this operation.

Dependencies

• Requires an active connection to a Dataiku DSS instance.
• Requires an API key credential for authentication with the Dataiku DSS API.
• The node expects the Dataiku DSS server URL and user API key to be configured in the credentials.
• No additional environment variables are needed beyond the API credentials.

Troubleshooting

• Missing Credentials Error: If the node throws "Missing Dataiku DSS API Credentials," ensure that the API key credential is properly set up and linked to the node.
• Project Key Required: For listing model comparisons, the "Project Key" property must be provided; otherwise, the node will throw an error indicating this requirement.
• API Request Failures: Network issues, incorrect server URLs, or invalid API keys can cause request failures. Verify connectivity and credentials.
• Unexpected Response Format: If the API response cannot be parsed as JSON, check if the Dataiku DSS server is returning valid JSON or if there are permission issues.
