I get this on linux with version 2.2.0. This happens in linux and works well in Mac.

@abratnap please check if there is a mismatch between Milvus and Milvus SDK version. This also happens to me with Milvus and PyMilvus in Python, as specified in https://github.com/milvus-io/pymilvus

Check the release note here https://milvus.io/docs/release_notes.md.
It's better to match Milvus version and SDK version in each release.

2.2.

Did you solve this problem(unknown method GetLoadingProgress for service)? What solved it? @abratnap

[xiaofan-luan]

@yhmo
could you help on that?
Might be work for java SDK?

I think this error is raised from CheckHealth interface. This CheckHealth interface was added lately in milvus which might not be available in old version of Milvus. Since you are using older version of milvus, i think upgrading Milvus to latest version will solve this issue.

Facing the same issue when I load the data into collection using collection.load()
pymilvus-2.2.1
milvus-cli-0.3.2

I have tried upgrading and downgrading them but any other combination results in compatiblity issue
I am able to create the collection but unable to load data into it.
collection.insert(df) shows success but collection.is_empty results in True.

Error:

pymilvus.exceptions.MilvusException: <MilvusException: (code=1, message=<_MultiThreadedRendezvous of RPC that terminated with:

The GetLoadingProgress API is available from Milvus v2.2.1. You will get this error if you are using Milvus 2.1.x.
