DETRsegm to torchscript

[Zalways]

I have been able to successfully convert the DETR model into torchscript. But when I'm trying to convert my trained segmentation model DETRsegm I got the following error:

  File "/opt/conda/envs/torch_apps/lib/python3.8/site-packages/torch/jit/_recursive.py", line 393, in create_methods_and_properties_from_stubs
    concrete_type._create_methods_and_properties(property_defs, property_rcbs, method_defs, method_rcbs, method_defaults)
RuntimeError:

Inferred 'mask' to be of type 'Tensor' because it was not annotated with an explicit type.

hi you said you export detr into torchscript successfully, i'd like to know your export code. do you use the detectron2's official export_model.py(https://github.com/facebookresearch/detectron2/blob/main/tools/deploy/export_model.py) to export the model?
