I guess your milvus is not 2.4.14. Both the pymilvus 2.4.9 and java sdk 2.4.7 work very well with milvus 2.4.14.

[fgyang]

this is my pymilvus version and milvus version

Show me the test.py

[fgyang]

import pymilvus from pymilvus import MilvusClient

if name == 'main': print(pymilvus.version)

client = MilvusClient(
    uri='http://124.71.208.220:19530',  # replace with your own Milvus server address
    # uri='http://192.168.0.150:19530',  # replace with your own Milvus server address
    # uri='http://192.168.1.105:19530',  # replace with your own Milvus server address
    # uri='http://223.247.150.167:19530',  # replace with your own Milvus server address
    token="root:Milvus"
)

if client.has_collection(collection_name="demo_collection"):
    client.drop_collection(collection_name="demo_collection")
client.create_collection(
    collection_name="demo_collection",
    dimension=768,  # The vectors we will use in this demo has 768 dimensions
)

You got the error "this version of sdk is incompatible with server, please downgrade your sdk or upgrade your server" at this line?

client = MilvusClient(
......

Seems you have several milvus addresses: uri='http://124.71.208.220:19530' uri='http://192.168.0.150:19530' uri='http://192.168.1.105:19530' uri='http://223.247.150.167:19530'

Are these milvus servers different versions? Maybe you wrongly choose an old version?

The error "this version of sdk is incompatible with server, please downgrade your sdk or upgrade your server" happens when you are using a high version pymilvus connect to a milvus version older than v2.2.9.
