What is Kubeflow Pipelines The specified workflow cannot be found in the Kubeflow Pipelines system.

Understanding Kubeflow Pipelines

Kubeflow Pipelines is a platform for building and deploying portable, scalable machine learning (ML) workflows based on Kubernetes. It provides a set of tools for orchestrating ML workflows, enabling data scientists and engineers to automate and manage the end-to-end ML lifecycle.

Identifying the WorkflowNotFound Symptom

When working with Kubeflow Pipelines, you might encounter an error message stating WorkflowNotFound. This indicates that the system is unable to locate the specified workflow. This error can be frustrating, especially when you are certain that the workflow should exist.

Common Observations

Attempting to view or manipulate a workflow results in an error message. The workflow does not appear in the list of available workflows.

Explaining the WorkflowNotFound Issue

The WorkflowNotFound error occurs when the Kubeflow Pipelines system cannot find the workflow you are trying to access. This can happen due to several reasons, such as an incorrect workflow ID or name, or the workflow not being created successfully.

Possible Causes

Typographical errors in the workflow ID or name. The workflow was not created or was deleted. Network issues preventing access to the Kubeflow Pipelines system.

Steps to Resolve the WorkflowNotFound Issue

To resolve the WorkflowNotFound error, follow these steps:

Step 1: Verify Workflow ID or Name

Ensure that the workflow ID or name you are using is correct. Double-check for any typographical errors. You can list all workflows to verify:

kubectl get workflows -n kubeflow

This command will list all workflows in the kubeflow namespace. Ensure the workflow you are looking for is listed.

Step 2: Confirm Workflow Creation

If the workflow is not listed, it may not have been created. Check the logs of the pipeline run to ensure there were no errors during creation:

kubectl logs -n kubeflow

Replace <pipeline-run-pod> with the actual pod name of your pipeline run.

Step 3: Check for Deletion

If the workflow was previously available, it might have been deleted. Review the audit logs or check with team members to confirm if the workflow was intentionally removed.

Additional Resources

For more information on managing workflows in Kubeflow Pipelines, refer to the official Kubeflow Pipelines Documentation. If you continue to experience issues, consider reaching out to the Kubeflow community for support.

By following these steps, you should be able to resolve the WorkflowNotFound error and continue working with your Kubeflow Pipelines efficiently.
