Qwen2-VL-2B vision tower optimized for RK3588, achieves 4.45s inference

By PulseAugur Editorial · [1 sources] ·

A developer successfully optimized the Qwen2-VL-2B model's vision tower to run on an RK3588 board, achieving a median inference time of 4.45 seconds for image encoding. This was accomplished by carefully identifying and pinning specific versions of the `transformers` and `torch` libraries, as older versions caused compatibility issues with the model's components. The process involved converting the vision model to ONNX and then to RKNN format, with the final on-device execution showing no runtime errors, though the language model component is still pending integration.

    From five broken transformers versions to 4.45 seconds on the board: getting Qwen2-VL-2B's vision tower onto an RK3588

    <p>Two days ago this model wouldn't even export. Today its vision tower runs on a real RK3588 board: a 392×392 image encoded in <strong>4,445.68 ms</strong> (median of three independent processes), model load about 7.3 seconds, zero RKNN errors at runtime. This is a field note fr…
