model: Model uid not model name, sometimes they may be the same (e.g.,bge-reranker-base).base_url: base url of Xinference (e.g.,http://localhost:9997).top_n: Top n nodes to return from reranker. (default 5).
Nodes Rerank Example
from llama_index.postprocessor.xinference_rerank import XinferenceRerank
xi_model_uid = "xinference model uid"
xi_base_url = "xinference base url"
xi_rerank = XinferenceRerank(
top_n=5,
model=xi_model_uid,
base_url=xi_base_url,
)
def test_rerank_nodes(nodes, query_str):
response = xi_rerank.postprocess_nodes(nodes, query_str)
