Local inference

from FlagEmbedding import FlagReranker

class RerankRequest(BaseModel):
    query: str
    documents: list[str]

# Prepare array
arr = []
for element in request.documents:
    arr.append([request.query, element])
print(arr)

# Inference
reranker = FlagReranker('netandreus/bge-reranker-v2-m3', use_fp16=True)
scores = reranker.compute_score(arr, normalize=True)
if not isinstance(scores, list):
    scores = [scores]
print(scores)  # [-8.1875, 5.26171875]
