Request: Provide PyTorch pre-trained model and training code (if possible) for sherpa-onnx-kws-zipformer-zh-en-3M-2025-12-20

[TwilightShd]

thank you for your excellent work!

I am interested in the model sherpa-onnx-kws-zipformer-zh-en-3M-2025-12-20 (Chinese & English). I would like to fine-tune it for my own use case. To do so, I need the following resources:

• PyTorch pre-trained model (original weights before conversion to ONNX)

• Training code, especially the tokens/lexicon part

Thank you in advance for your time and help!
