nomadrt (real time)

implementation of NoMAD with tensorrt for running on edge devices.

convert from pytorch to onnx

python onnx_export.py -i nomad.pth -t config/nomad.yaml -o weights

convert onnx models to tensorrt's engine

cd weights
trtexec --onnx=action.onnx --best --useCudaGraph --saveEngine=action.engine
trtexec --onnx=encoder.onnx --best --useCudaGraph --saveEngine=encoder.engine
trtexec --onnx=distance.onnx --best --useCudaGraph --saveEngine=distance.engine

compile the ros2 package

colcon build --symlink-install
