Unable to run deepstream-test2-app example

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

Hey!

I pulled the docker container “nvcr.io/nvidia/deepstream:4.0.2-19.12-devel” and tried to run the example deepstream-test2-app with the video file sample_1080p_h264.mp4 file but keep getting the error “One element could not be created. Exiting”.

Here’s my output when I set GST_DEBUG=4:

GST_DEBUG=4 deepstream-test2-app samples/streams/sample_1080p_h264.mp4

As you can see, I keep getting

gstelementfactory.c:456:gst_element_factory_make: no such element factory "nvinfer"

but I do not know how to fix it. Any ideas?

Thanks!

Hi,
Can you please check if nvinfer is listed when running gst-inspect?,
If not, which nv plugins are listed?

  • Which hardware platform are you using?

Thanks

I don’t see nvinfer within the list. I do see:

nvdsgst_dewarper:  nvdewarper: nvdewarper
nvdsgst_eglglessink:  nveglglessink: EGL/GLES vout Sink
nvdsgst_segvisual:  nvsegvisual: nvsegvisual
nvdsgst_msgconv:  nvmsgconv: Message Converter
nvdsgst_multistreamtiler:  nvmultistreamtiler: Stream Tiler DS 4.0
nvdsgst_of:  nvof: nvof
nvdsgst_tracker:  nvtracker: NvTracker plugin
nvdsgst_msgbroker:  nvmsgbroker: Message Broker
nvdsgst_ofvisual:  nvofvisual: nvofvisual
nvdsgst_multistream:  nvstreammux: Stream multiplexer
nvdsgst_multistream:  nvstreamdemux: Stream demultiplexer
nvdsgst_jpegdec:  nvjpegdec: JPEG image decoder
nvdsgst_osd:  nvdsosd: NvDsOsd plugin
nvdsgst_dsexample:  dsexample: DsExample plugin

I’m using a Ubuntu 16.04 but running the Ubuntu 18.04 Docker image “deepstream:4.0.2-19.12-devel”

EDIT: I actually see this output sometimes in the output when running gst-inspect-1.0

(gst-plugin-scanner:749): GStreamer-WARNING **: 15:43:22.584: Failed to load plugin '/opt/nvidia/deepstream/deepstream-4.0/lib/gst-plugins/libnvdsgst_infer.so': libnvrtc.so.10.2: cannot open shared object file: No such file or directory

Now here are some new questions. I have all the CUDA 10.1 toolkit installed as part of the docker container but it seems like it’s trying to open a CUDA 10.2 object. Is this normal? It seems as if I’m missing libnvrtc.so.10.2. Is this a new requirement for TensortRT ?

  1. Only elementary streams (.h264) are supported in test 2 and is documented in Readme.
  2. U should check display driver version on host machine - should be 418+
  3. U should clean gstreamer cache and try first through docker. Else u should try on ubuntu 18.04 host
    BTW, Have u updated anything inside the docker via sudo apt-get?

Hi,
Can you find any libnvrtc.so?
(On / folder run: find . | grep libnvrtc)
+
What does your environment variables show with regards to cuda?

Thanks

Hi
Sorry for a late reply, have you solved this issue? by default, after you pulled the docker container, you can run directly, you do not need to reinstall cuda.
