Hi @krishung5 @rmccorm4, do you have any concern if the gRPC version on the client is newer than the one on the server?

The server is currently on 1.54.3, and this change will set the version on the client to 1.67.1

@kthui The current client version specification before this change (>=1.63.0) is already higher than the server version you pointed to, and hasn't given us any issues I'm aware of, so I have no issue with this change.

However, @mc-nv can you add details on the reason/context in the Description of these types of PRs so in the future looking backwards we can better understand why this change was made?

Found this issue trying to understand why grpcio is being restricted to <1.68. Are there plans to allow the latest grpcio release (1.76.0)?

Asking because I'm noticing that the latest grpcio release (1.76.0) supports binary wheels for python 3.14 but the 1.68 release does not. I can likely workaround this, but currently hitting this compile error (hence why I'm curious about supporting more recent grpcio to make this a non-issue):

I'm hoping that underlying issue has now been resolved? Here is a PR to loosen requirements at #862, that should work if my assumption holds :)

Hello. This pinning avoids the use of Python 3.14. Can you please fix this? Thanks!
