Sample failures when working with deepstream 4 docker

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi,
I am trying to run deepstream 4 docker version, however most of the samples fail

Environment on my desktop:
Docker version 19.03.2, build 6a30dfc
NVIDIA-SMI 418.87.00
CUDA Version: 10.1
GeForce RTX 2060
sudo nvidia-docker run -it --rm -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -w /root nvcr.io/nvidia/deepstream:4.0-19.07

Examples for failed samples
$ deepstream-app -c ./config_infer_secondary_carcolor.txt

(deepstream-app:36): GStreamer-CRITICAL **: 11:13:47.906: gst_element_get_static_pad: assertion ‘GST_IS_ELEMENT (element)’ failed
Segmentation fault (core dumped)

$ deepstream-app -c ./source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8_gpu1.txt
Unable to set device in gst_nvstreammux_change_state

** ERROR: main:651: Failed to set pipeline to PAUSED

Unable to set device in gst_nvstreammux_change_state
App run failed

Example for successful sample
$ deepstream-app -c ./source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

I have few questions:

  1. Why the above sample fails?
  2. How can I use deepstream 4 docker without the above problems?

Please assist

Thanks,
Rami

deepstream-app -c ./config_infer_secondary_carcolor.txt
you can not use this directly, its secondary gie configuraton, it used in as like source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

deepstream-app -c ./source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8_gpu1.txt
How many nvidia GPU cards in your system, if just one, please not use this, it’s for second GPU if there above
or equal 2 GPU in your system.
