Pull request overview

This PR removes the deprecated MediaPipe RerankCalculator implementation and its associated proto/config artifacts, keeping the OpenVINO-based RerankCalculatorOV as the supported path.

Changes:

• Deleted the deprecated RerankCalculator C++ implementation and its RerankCalculatorOptions proto.
• Removed Bazel targets and server build references to the deprecated calculator.
• Updated demos/test assets to stop exporting/whitelisting the deprecated calculator (but one test graph/config path still needs follow-up to stay consistent).

This file should look like src/test/rerank/graph_ov.pbtxt but with max_allowed_chunks and max_position_embeddings parameters

[SaumyaTiwari108]

Understood! I had blindly accepted the automated GitHub Copilot PR reviewer suggestion to fix the missing node ,I'll update this file to match your instructions

[michalkulakowski]

Both OpenVINOModelServerSessionCalculator's should be removed since RerankCalculatorOV does not use them

[SaumyaTiwari108]

done...please check once

[michalkulakowski]

@SaumyaTiwari108 please explain these changes

[SaumyaTiwari108]

Ah, My apology sir! My codespace environment accidentally auto-updated this file in the background and it slipped into the commit. I did not mean to change this. I will revert 'yarn.lock' back to the original main branch version right now.

[michalkulakowski]

ok. please revert then

Sir @michalkulakowski,
I'm really sorry but I'm not able to understand why it's failing(1 failing check)

I want to contribute but seems like I'm not capable enough...can you please help me out to make me capable to contribute for your organisation if not this year(gsoc) then next year...

You can run unit tests yourself and debug further.
Here is documentation how to build image yourself and also how to run single unit test: https://github.com/openvinotoolkit/model_server/blob/main/docs/developer_guide.md

It looks like you forgot to remove unit tests from the source file. But please verify yourself as well :)
