RuntimeError: Could not export Python function call 'MSDeformAttnFunction'. Remove calls to Python functions before export. Did you forget to add @script or @script_method annotation? If this is a nn.ModuleList, add it to __constants__:

[Zalways]

when i try to export the deformable detr model into torchscript,it shows the error message!

anybody knows how to solve it?
i tried the method:

it exported successfully,but the exported model doesn't work! and when i use this exported model to inference,it shows the error message:
