Vertex AI | Deploy | 400 Model server never became ready

Hi.

I have developed a simple sklearn regression model (locally) that I’d like to deploy to an endpoint.

I’ve read a few links (some from the community, some official) so I’ve been able to train the model, register the model and create an endpoint. But I can’t deploy the model to an endpoint. The message I usually get is : 400 Model server never became ready

Can you help: Is there a different link I should follow directions from?

Hi @Toobs4,

Welcome to Google Cloud Community!

It seems you’re trying to deploy a regression model (created with sklearn) to an endpoint but encountering the error message, “400 Model server never became ready.” This error usually points to an issue with the deployment process, such as the model format, endpoint configuration, or resource allocation.

Here’s what might be going wrong and some possible ways to address the issue:

  • Missing Package Requirement Issues: Your model likely relies on specific libraries (like scikit-learn, pandas, etc.) that aren’t installed in the Vertex AI serving environment. Ensure that you include all dependencies (like scikit-learn and any other libraries you used) when setting up the model in the cloud environment. Most platforms let you define these in a requirements file (like requirements.txt for Python).
  • Endpoint Configuration: In some cases, an incorrect endpoint setup can cause issues. Make sure your endpoint is properly configured. If necessary, try deleting and recreating the endpoint.
  • Stale Model Artifacts: Sometimes, if you update your model but don’t update it in Vertex AI, problems can occur. When you update your model, make sure to register the new version with the updated files, and then deploy it to the endpoint.
