Thanks for updating this @tenzen-y!
Since we don't have proper tests in SDK to verify the GRPC lib functionality yet, can we update the versions in other Katib services as well. For example, tf event collector and other Suggestion services.

[tenzen-y]

You're right.
I will change the versions in this PR.

[tenzen-y]

Done.

It seems that we must use the protobuf version lower or equal to v3.20.

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

[tenzen-y]

Maybe, we must regenerate codes using a newer protoc in follow-up PRs.

@tenzen-y @johnugeorge We currently, use znly/protoc image to update our proto APIs..
It seems that this images have not been updated for 4 years: https://hub.docker.com/r/znly/protoc/tags.
Should we consider alternative ?

[tenzen-y]

Should we consider alternative ?

@andreyvelich I agree. However, I think we can do that in another PR. wdyt?

[andreyvelich]

@tenzen-y Sure, please can you create an issue to track it ?
