Request for the new notebook which implement Catboost into openVINO

[Fraapp24]

I tried to implement on OpenVINO a Catboost implemented by me, before I had to transform the Catboost to ONNX, and then from ONNX to OpenVINO. When I run the code the following warning appeared: "OpenVINO does not support the following ONNX operations: ai.onnx.ml. TreeEnsembleRegressor". How can I solve this problem? Is there a way to extend OpenVINO to include the above ONNX operations?

Hello @Fraapp24,

Thanks for reaching OpenVINO! You can follow this guide to prepare ONNX Frontend extension https://docs.openvino.ai/2023.2/openvino_docs_Extensibility_UG_Frontend_Extensions.html in case it is possible to represent it via existing OpenVINO operations. More details in the Extension API guide: https://docs.openvino.ai/2023.2/openvino_docs_Extensibility_UG_Intro.html
