ShieldGemma model not supported #104

Closed lordofthejars closed 2 days ago

lordofthejars commented 2 days ago

Seems like the latest changes for supporting ShieldGemma (Gemma 2 classification model) aren't working in 0.8.0. I have the dependency and did a copy paste from your example but still I got:

Caused by: java.lang.UnsupportedOperationException: Classification not supported by this model

To run the demo run ./mvnw quarkus:dev in the project and curl localhost:8080/test

Seems something is wrong with my configuration.
