Milvus should be from langchain_milvus.vectorstores

[jameswnl]

Without this change, it will fail with

Invalid Milvus URI: ./milvus_demo.db

But even with this change, it still fail with

pymilvus.exceptions.MilvusException: <MilvusException: (code=2, message=Fail connecting to server on unix:/var/folders/r8/vnb_8wm96j151_t9yms3159c0000gn/T/tmpdudd4706_milvus_demo.db.sock, illegal connection params or server unavailable)>

@jameswnl thanks for your feedback .
https://github.com/langchain-ai/langchain-milvus/blob/main/libs/milvus/langchain_milvus/__init__.py
here the outermost layer declares the Milvus/Zilliz class, so there is no need to from langchain_milvus.vectorstores import Milvus
I think it's other reasons that cause your issues. So far Milvus Lite only support ubunbu >=20.04, and MacOS, can you provide your OS informations, as well as the langchain_milvus, and pymilvus, and milvus-lite versions
