            I pushed these containers:
            
            - `gcr.io/tensorflow-sigs/build:${{ github.event.number }}-python3.12`

            - `gcr.io/tensorflow-sigs/build:${{ github.event.number }}-python3.9`
            
            Re-apply the `build and push to gcr.io for staging` label to rebuild and push again. This comment will only be posted once.
