Research direction

Start with google-cloud-aiplatform setup.py at the dependency declaration cited in the issue, then compare it with grpcio-tools 1.83.0 metadata. Verify the updated range using pip download and confirm that the package can be installed alongside a supported grpcio-tools release.

Written by the indexing model from the issue text.

Description

api: vertex-ai

google-cloud-aiplatform pins protobuf<7.0.0, but grpcio-tools>=1.83.0 requires protobuf>=7.35.1. These two ranges don't overlap, so this package can't be installed alongside a current grpcio-tools.

Checked via pip download <pkg> --no-deps and reading METADATA:

  • google-cloud-aiplatform==2.1.0: protobuf!=4.21.0,...,!=4.21.5,<7.0.0,>=3.20.2
  • grpcio-tools==1.83.0: protobuf<8.0.0,>=7.35.1, grpcio>=1.83.0

Also, source:

gRPC only supports the current release and the one before it (FAQ), and ships roughly every 6 weeks. 1.83.0 came out 2026-07-21, so the next release will drop support for everything below it — at that point there's no supported grpcio left that's compatible with this cap.

Can you bump the protobuf upper bound (<8.0.0 would match grpcio-tools) so the package stays installable with a supported gRPC
version?
Thanks!
