How to export models to RKNN for sherpa-onnx

Please don’t use RKNN models from https://github.com/airockchip/rknn_model_zoo/tree/main/examples/zipformer

Warning

Many users use models from rknn model zoo in sherpa-onnx and get errors. That’s expected.

Please never do that.

If you want to export models from icefall, please see
