The FasterRCNN sample uses the dataset from here: https://dl.dropboxusercontent.com/s/o6ii098bu51d139/faster_rcnn_models.tgz
The dataset needs to be placed into the data/faster-rcnn directory.
The commands to do this on linux are as follows:
cd
src: /usr/src/tensorrt/samples/ model and data: /usr/src/tensorrt/data/faster-rcnn
Convert to INT8 Refer to sampleINT8 in tensorrt examples
