Please advise on how to convert PT model to ONNX.

Hello:
I found your repo., it looks great. However, I am rather new to Python language, but I have rather good experience with C#, and have some experience with ONNX models. I am using Python 3.9 on Windows 10.
I want to know if I can convert any of the PT model, like: 550000.PT to onnx model, like: 550000.onnx.
I have installed Netron 5.6.4, and I can view 550000.PT file, it looks very complicated.
Can you suggest on how to do this?
I found someone showed some Python script to convert other type of model to ONNX, but it seems they know the model very well. But I don’t know too much about any model used in your repo.
Please advise,
Thanks,
