Open source status

• [X] The model implementation is available on transformers
• [X] The model weights are available on huggingface-hub
• [ ] I verified that the model is currently not running in the lastest version pip install infinity_emb[all] --upgrade

To resolve the issue with the model BAAI/bge-reranker-v2-gemma having embedding capabilities but no rerank, follow these steps:

1. Locate Model Definition: Open models.py and find the class definition for BgeRerankerV2Gemma.

2. Add Rerank Capability: Ensure the class includes a method for reranking. For example:

class BgeRerankerV2Gemma(BaseModel):
    def __init__(self, ...):
        super().__init__(...)
        # existing initialization code

    def rerank(self, inputs):
        # Add reranking logic here
        pass

3. Update Capabilities: In the same file, update the capabilities list to include rerank.

self.capabilities = ["embed", "rerank"]

4. Ensure Backend Support: Verify that the backend specified (torch) supports the reranking operation. This might involve checking or updating backend.py.

5. Configuration: Ensure the model configuration file (likely config.json or similar) reflects the new capabilities.

{
  "capabilities": ["embed", "rerank"]
}

These steps should add the rerank capability to the model.
