paraformer 模型无法使用 coreml provider about sherpa-onnx

[csukuangfj]

其他模型可以么？

有没有试过 int8.onnx ?

你是 macos 么?

[XUJiahua]

我是 MacOS。
sherpa-onnx-streaming-zipformer-ctc-multi-zh-hans-2023-12-13.tar.bz2 这个模型可以。
paraformer int8 也是一样的问题。

这个问题我解决不了，不好意思。

[XUJiahua]

谢谢及时反馈！

可能就是 onnx runtime 的 coreml provider 有问题。我找到另一个使用 onnx runtime 推理 paraformer 模型的例子，遇到一样的问题。

[csukuangfj]

你自己导出这个模型试试？

[XUJiahua]

我试试，有导出脚本可参考么，我看需要将原 pytorch 模型拆成 encoder, decoder 后分别导出。
