hi,

I've followed the steps to build the app, and directly download the libnvinfer_plugin.so.8.0.1 from:

after i run the detection app, always got an error, could you help:

./ds-tao-detection -c ../../configs/frcnn_tao/pgie_frcnn_tao_config.txt -i /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264 -d Now playing: ../../configs/frcnn_tao/pgie_frcnn_tao_config.txt
