@justram I believe this was introduced by #1828

TypeError: init_query_encoder() missing 1 required positional argument: 'multimodal'

issue fixed, tested with the following CLI & Python interface test case

python -m pyserini.search.hybrid \
run --topics msmarco-passage-dev-subset \
      --output runs/run.fusion.trec \
      --batch-size 32 \
      --threads 16 \
dense --index msmarco-passage-tct_colbert-hnsw \
           --encoder castorini/tct_colbert-msmarco \
sparse --index msmarco-v1-passage \
fusion --hits 1000
