export the model into torchscript

[Zalways]

Has anyone tried exporting a model to a C++ environment for inference? I have encountered some problems while dealing with this step and would like to receive your help.(the net is based deformable detr,)
I had some problems converting and exporting the model, but I finally got the model through the trace method, but there was a problem with this model.
RuntimeError: The size of tensor a (32) must match the size of tensor b (237) at non-singleton dimension 1
i need your help!
