Hey there, new to the community.
A while ago, I was building a similarity search module and then using llama_index
RetrieverQueryEngine.
I was initially using v0.6.20 so I was building the
response_synthesizer like this:
response_synthesizer = ResponseSynthesizer.from_args(
node_postprocessors=[
SimilarityPostprocessor(
similarity_cutoff=config_params["retrieval"]["similarity_cutoff"]
)
]
)However, when I imported Node:
from llama_index.data_structs import Node
, I started getting the error
ImportError: cannot import name 'BaseCache' from 'langchain'
.
I updated the llama_index version to 0.8.64.post1 but I think
ResponseSynthesizer was updated.
I can't seem to find how to use node_postprocessors with the
get_response_synthesizer. I may be missing something basic, any suggestions?
Thanks
