# Description

Updates onnx and protobuf versions as previous dependency versions had
security vulnerabilities.

To avoid onnx 1.16.1, we are updating onnx to 1.18.0
To avoid protobuf 3.20.3, we are updating protobuf to 6.31.1

Also included some minor updates to add one more flaky test annotation
for test failure, and adding random_state to GaussianProcessRegressor to
resolve another security risk for non-reproducible results.
