Seldon Core is an open-source platform designed to deploy machine learning models on Kubernetes. It provides a robust infrastructure to manage, scale, and monitor models in production environments. By leveraging Kubernetes, Seldon Core ensures that machine learning models are scalable and resilient, making it a popular choice for enterprises looking to operationalize their AI solutions.
When deploying models with Seldon Core, you might encounter an error related to an API version mismatch. This typically manifests as a failure in communication between the client and the server, often resulting in error messages indicating that the API versions are incompatible.
The API version mismatch occurs when the client and server components of Seldon Core are using different versions of the API. This can happen if the client library is updated without updating the server, or vice versa. The mismatch prevents successful communication and can disrupt model deployment and management.
API compatibility is crucial for seamless operation. Seldon Core follows semantic versioning, which means that breaking changes are introduced only in major version updates. Ensuring that both client and server are on compatible versions is essential for avoiding these issues.
To resolve the API version mismatch, follow these steps:
First, verify the versions of both the client and server. You can check the client version by running:
pip show seldon-core
For the server version, you can inspect the Seldon Core deployment in Kubernetes:
kubectl get deployment -n seldon-system -o jsonpath='{.items[*].spec.template.spec.containers[*].image}'
Ensure that both the client and server are updated to compatible versions. You can update the client using pip:
pip install seldon-core --upgrade
For the server, update the Seldon Core Helm chart:
helm upgrade seldon-core seldon-core-operator --namespace seldon-system
Refer to the official Seldon Core installation guide for more details.
After updating, verify that the versions are compatible. Check the Seldon Core versioning documentation to ensure compatibility between the client and server versions.
By ensuring that both the client and server components of Seldon Core are using compatible API versions, you can resolve the API version mismatch issue. Regularly checking for updates and understanding the versioning policy of Seldon Core will help prevent such issues in the future.
