Bug in langchain-milvus import package

[saikumar0605]

Hi team,
I found a bug in your latest Milvus package. The old version was running well, but the latest package had a bug, which took me almost three days to figure out. the new package has a hardcode saying localhost. even if we give server configurations yet its localhost. please check the document below for details and solve it. happy to use the updated package.
Thank you, team.

@saikumar0605 Thank you very much.
Maybe there is something wrong with the import code,
it should be

from langchain_milvus import Milvus

, not

from langchain_milvus import milvus

To ensure correct, please ensure that you have updated to the latest version

pip install -U langchain_milvus

no @zc277584121 it's the same issue I have checked the below image.

the exact problem is I guess in the package somewhere there is localhost hardcoded. for server IP address.

here I get this log as well = Connecting to Milvus at 100.205.208.00:19530
I have added dummy IP address but it shows this. and error is attached below. its package problem only.

{
"error": "Failed to connect to Milvus: <MilvusException: (code=2, message=Fail connecting to server on localhost:19530, illegal connection params or server unavailable)>"
}

please check the error why it will show localhost:19530. it should show my IP address for error right??

This error seems strange. Under normal circumstances, it shouldn't occur. Can you show your langchain_milvus package version? It will be appreciated if there are more error stack information which can be helpful to locate the original issue.

BTW, can you try this code to see whether this issue would occur again

from pymilvus import (
    Collection,
    CollectionSchema,
    DataType,
    FieldSchema,
    MilvusClient,
    MilvusException,
    RRFRanker,
    WeightedRanker,
    utility,
)
from pymilvus.client.types import LoadState 
from pymilvus.orm.types import infer_dtype_bydata

This pypi package is depracated, maybe the issue is caused from it. https://pypi.org/project/milvus/

Maybe you can uninstall milvus, then start a milvus service by milvus-lite/docker/zilliz, and then try your code again.
