ZenML Failed to upload an artifact to the artifact store.
ZenML Failed to upload an artifact to the artifact store.
Understanding ZenML and Its Purpose
ZenML is an extensible, open-source MLOps framework designed to create reproducible machine learning pipelines. It provides a structured approach to building and deploying machine learning models, ensuring that every step of the process is trackable and repeatable. ZenML integrates seamlessly with popular machine learning tools and platforms, making it a versatile choice for data scientists and engineers.
Identifying the Symptom: ARTIFACT_UPLOAD_FAILED
When working with ZenML, you might encounter the error code ARTIFACT_UPLOAD_FAILED. This error typically manifests when ZenML is unable to upload an artifact to the configured artifact store. Artifacts in ZenML are crucial components, as they represent the outputs of various pipeline steps, such as models, datasets, or metrics.
Exploring the Issue: Why Does ARTIFACT_UPLOAD_FAILED Occur?
The ARTIFACT_UPLOAD_FAILED error indicates a failure in the process of uploading an artifact to the artifact store. This could be due to several reasons, such as incorrect configuration settings, network issues, or insufficient storage space in the artifact store. Understanding the root cause is essential for resolving this issue effectively.
Common Causes of the Error
- Incorrect artifact store configuration: The settings might not match the actual storage service being used.
- Network connectivity issues: The network might be down or experiencing high latency.
- Insufficient storage space: The artifact store might be full or have limited capacity.
Steps to Fix the ARTIFACT_UPLOAD_FAILED Issue
To resolve the ARTIFACT_UPLOAD_FAILED error, follow these detailed steps:
Step 1: Verify Artifact Store Configuration
Ensure that the artifact store is correctly configured in your ZenML setup. Check the configuration file or environment variables for any discrepancies. For example, if you are using an S3 bucket, verify the bucket name, access keys, and region settings.

Use the above command to review the current artifact store configuration.
Step 2: Check Network Connectivity
Ensure that your network connection is stable and that there are no firewall rules blocking access to the artifact store. You can test connectivity using tools like ping or curl to the artifact store endpoint.
Step 3: Ensure Sufficient Storage Space
Verify that the artifact store has enough space to accommodate new artifacts. If using a cloud service, check the storage quotas and consider upgrading if necessary.
Step 4: Retry the Upload
After verifying the configuration and network, attempt to re-run the pipeline or manually upload the artifact again. This can often resolve transient issues.
