Yolov2 weights not working on deepstream plugin on jetson tx2


We are creating sample for object detection from deepstream-yolo on jetson tx2, when i try to make build it works fine. We are using Jetson tX2 with JetPack 3.3 and deepstream plugin has only detect tiny-yolo. Can you please give me more suggestion or where we change for yolov2 weights/ yolov3.weights but its not works. Here are the commands i have try;

For tegra,
$cd sources/plugins/gst-yoloplugin-tegra
make && sudo make install
$ nvgstiva-app -c config/nvgstiva-app_yolo_config.txt
