Detectron 2 → ONNX → TensorRT [Bug] KeyError: 'UNKNOWN_SCALAR'. When

1、I guarantee I followed the instructions on the README carefully.

2、The only difference is I used my custom data, I’m wondering if the conversion can’t be done after using the custom data?
(According to my understanding, after using custom dataset, only the weight of the model has changed, but the structure of the model has not changed, so Detectron 2 → ONNX → TensorRT should work as well. I don’t know if the current conversion can only be done for Mask R-CNN R50-FPN 3x? Or we can also convert the transfer learning model with custom dataset?).

3、.yaml file changed a little bit for transfer learning.

Thank you.

Hi dear Moderator,

I have already tried to solve this problem for a month… But still didn’t achieve.

I already reach out to Issues · NVIDIA/TensorRT · GitHub , but no one answer.

Could you please help me…
