Describe the bug

I'm running milvus standalone 2.3.5 and pymilvus 2.3.5. These are the recommended versions according to release notes. However, when I use connections.connect(), I get the error:

E               pymilvus.exceptions.MilvusException: <MilvusException: (code=1, message=this version of sdk is incompatible with server, please downgrade your sdk or upgrade your server)>

Expected Behavior

I expect connections.connect() to connect.

Steps/Code To Reproduce behavior

No response

Environment details

- Hardware/Softward conditions (OS, CPU, GPU, Memory): Archlinux
- Method of installation (Docker, or from source): docker standalone
- Milvus version (v0.3.1, or v0.4.0): v2.3.5

Anything else?

Turns out it's that you don't use connect at all anymore. Should just instantiate the Milvus object in 2.3.4+
