Kubeflow Pipelines InvalidPipelineVersion error encountered when trying to run a pipeline.

What is Kubeflow Pipelines InvalidPipelineVersion error encountered when trying to run a pipeline.

Understanding Kubeflow Pipelines

Kubeflow Pipelines is a platform for building and deploying portable, scalable machine learning (ML) workflows based on Docker containers. It provides a set of tools to compose, deploy, and manage ML workflows on Kubernetes. The platform is designed to enable rapid and reliable experimentation, and it supports end-to-end orchestration of ML pipelines.

Identifying the Symptom

When working with Kubeflow Pipelines, you might encounter an error message stating InvalidPipelineVersion. This error typically appears when you attempt to execute a pipeline run with a version that the system cannot recognize or locate.

Common Error Message

The error message might look something like this:

Error: InvalidPipelineVersion - The specified pipeline version is invalid or does not exist.

Exploring the Issue

The InvalidPipelineVersion error occurs when the pipeline version specified in your request does not match any existing versions in the Kubeflow Pipelines system. This can happen due to a typo, a deleted version, or a version that was never created.

Why This Happens

Typographical Errors: A simple typo in the version string can lead to this error. Non-existent Version: The version may not have been created or might have been deleted. Incorrect Reference: The pipeline version might be referenced incorrectly in the code or configuration.

Steps to Fix the Issue

To resolve the InvalidPipelineVersion error, follow these steps:

Step 1: Verify the Pipeline Version

Ensure that the pipeline version you are trying to use exists. You can list all available pipeline versions using the Kubeflow Pipelines UI or the command line interface (CLI).

kubectl get pipelines -n kubeflow

Check the list of versions and confirm that the version you are using is present.

Step 2: Correct the Version Reference

If you find a typo or incorrect reference, update your code or configuration to use the correct version. Double-check the spelling and format of the version string.

Step 3: Create the Missing Version

If the version does not exist, you may need to create it. You can do this by uploading the pipeline again and specifying the desired version.

dsl-compile --py my_pipeline.py --output my_pipeline.yamlkubectl apply -f my_pipeline.yaml -n kubeflow
