TensorRT EP with custom op

[minrui-hust]

I have an model with custom ops, and I want to use tensorrt EP to accalarate my model.
Tensorrt EP requires shape info when create session, So I follow the link to do shape inference on my model, however it says my custom op has no schema rigistered. I registered my custom ops according to offcial guide, there is no way to register schema for custom op.
What should I do?
