I use deepstream-yolo-app like this:
sudo deepstream-yolo-app Tesla /home/mint/software/DeepStream_Release/samples/streams/sample_720p.h264 config/yolov3.txt
and I get a error:
One element could not be created. Exiting.
so i track and found yolo is null,but I try trt-yolo-app --flagfile=config/yolov3.txt ，it’s ok!
My gpu’s rtx2060 and opencv 3.4.6,is it has some problem?
I try this:
$rm ~/.cache/gstreamer-1.0/registry.x86_64.bin
base) mint@mint-B85M-D3H:~/ai/trt/deepstream_reference_apps/yolo$ gst-inspect-1.0 -b
(base) mint@mint-B85M-D3H:~/ai/trt/deepstream_reference_apps/yolo$ GST_DEBUG=3 gst-inspect-1.0 libgstnvyolo.so
0 features:
any idea can suggestion?

Hi,
Which OS are you using currently ?
Can you check if there are any missing dependencies using ldd ? You can use the command -
$ldd /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstnvyolo.so
Please run
$GST_DEBUG=3 gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstnvyolo.so
immediately after clearing the cache with
$rm ~/.cache/gstreamer-1.0/registry.x86_64.bin
My OS is Ubuntu 18.04.2 LTS
I try use ldd /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstnvyolo.so

It’s same correct.so I try:
GST_DEBUG=3 gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstnvyolo.so
无法载入插件文件: File "/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstnvyolo.so" is not a GStreamer plugin
Beacause libgstnvyolo.so is in blacklist ,so it couldn’t be load .

Deepstream 3.0 is not supported for Ubuntu 18.04 please use 16.04 or you can wait for DS4.0 which will be released soon.
