weight_query=True will result in an error

[luxinyayaya]

At line 16 of xrr2/retrievers.py, the following line throws an error that I’m unable to reproduce:

self.retriever = bm25s.BM25(k1=0.9, b=0.4, method='lucene', backend='numba', weight_query=True)

Hmm .. we use a forked version of bm25s w/ support for that weight_query parameter:
https://github.com/jataware/bm25s

Possibly this is a problem w/ installation (either on your end or in my pyproject.toml). How did you install the repo? And can you confirm you're using that forked bm25s?
