Unable to convert FRCNN: Warning: Encountered known unsupported method torch.Tensor.new_tensor

[Kaeseknacker]

Describe the bug
I installed the newest MMDetection version but can not convert a simple frcnn model.

mim download mmdet --config faster_rcnn_x101_64x4d_fpn_1x_coco --dest .

mmdet2trt --save-engine=true --min-scale 1 3 800 1312 --opt-scale 1 3 800 1333 --max-scale 1 3 800 1344 ./faster_rcnn_x101_64x4d_fpn_1x_coco.py ./faster_rcnn_x101_64x4d_fpn_1x_coco_20200204-833ee192.pth faster_rcnn_x101_64x4d_fpn_1x_coco_1-1-1-1333x800_fp16.trt --fp16 True

Any idea what happened here? FCOS works fine.

Warning: Encountered known unsupported method torch.Tensor.new_tensor can be ignored. Any tensor generated by torch.Tensor.new_tensor would be treated as a constant value. And I can convert this model on my device(2070 super, same as yours).
Would you mind updating the version of TensorRT? I haven't tested this repo on TensorRT7 for a long time. And don't forget to rebuild amirstan_plugin.

[Kaeseknacker]

Thanks for your reply. I have to test it with a newer TRT Version.
TRT 7.2.2.3 and cuda11.1 worked for me in the past with mmdet2.12 and mmdet2trt 0.4.0.
When do I have to rebuild amirstan_plugin? Everytime I switch to a new CUDA or TensorRT Version?

[grimoire]

Yes, a rebuild is required if you are using a new CUDA or TensorRT. And custom ops has been changed a lot since 0.4.
