Facing issue in setting up DeepStreamSDK-2.0 !!

Earlier I was using Deepstream1.0 and now wanted to upgrade to Deepstream2.0 to try out new features!!
Below is the issues which I am facing while doing the upgrade!!

Setup Details:

  • Ubuntu 18.04 LTS
  • GStreamer 1.14.1
  • NVIDIA driver 390.48
  • CUDA 9.2
  • TensorRT 4.0.1.6
  • Opencv 3.4.1
  • GPU :- GeForce GTX 1050 (Pascal)

All the gst plugins provided in DeepStreamSDK-2.0_EA_beta1.2/DeepStream_Release/binaries/usr/lib/x86_64-linux-gnu loaded successfully

Issues faced:-

Issue 1:-

Issue 4:- Also tried to compile and install gstreamer plugin gst-dsexample

~/DeepStreamSDK-2.0_EA_beta1.2/DeepStream_Release/sources/gst-plugins/gst-dsexample

But on gst-inspect it came as blacklisted

$:~/DeepStreamSDK-2.0_EA_beta1.2/DeepStream_Release/sources/gst-plugins/gst-dsexample$ gst-inspect-1.0 -b
Blacklisted files:
libgstnvdsexample.so

Total count: 1 blacklisted file

Please share me some pointers to debug the issue further !!
