deep learning algorithms

[serna01]

For the deep learning algorithms i got the following message:
$ ./IR --deeplearning --camera 0

[ WARN:0] global ./modules/videoio/src/cap_gstreamer.cpp (1100) open OpenCV | GStreamer warning: Cannot query video position: status=0, value=-1, duration=-1
build point model is failed!
build model is failed!
Segmentation fault (core dumped)

I am missing anything?
this has something to do with TRT models which also i cannot download from beidu servers
