This is a non-working WIP of gemma 3n vision implement in ggml. Commits are from June 2025 because it was under NDA before the model released.
I could not finished it on-time because testing was tricky and there was no native
transformersimplementation. My code was heavily based on mlx-vlm implementation: https://github.com/Blaizzy/mlx-vlm/blob/main/mlx_vlm/models/gemma3n/vision.pyIMPORTANT INFO: I am NOT actively working on this feature, but only pushing the PR for visibility.
Contributors can take over this task if needed.--> It's better to wait to see if their next model still use mobilenet architecture; if yes, we continue with this implementation, otherwise we drop it
