Hello,

We are trying to run example application given in deepstream SDK 5.1. I have cloned the example python application from: NVIDIA-AI-IOT/deepstream_python_apps

Here is my environment setup:

  • Ubuntu: 18.04
  • Python: python3
  • Gstreamer: 1.14.5
  • L4T: 32.6.1
  • Deepstrem SDK: 5.1
  • TensorRT: 8.0
  • CUDA: 10.2.300
  • CUDNN: 8.2.1

Tried to run deepstream application test 1 by following command and getting the error as below:

$ python3 deepstream_test_1.py /opt/nvidia/deepstream/deepstream-5.1/samples/streams/sample_720p.h264

As I can see from the log it is not able to create GPU inference engine and OSD.

Please help to resolve this issue.

Thanks and Regards
