Cannot start the application

[ynott]

Environment:

• HW: Jetson Xavier NX
• OS: JetPack 4.6.1

Expected behaviour

I can run the application.

Actual behaviour

I got the following error and could not start.

$ python3 run.py /dev/video0 --media v4l2 --cam-fps 10 
Traceback (most recent call last):
  File "run.py", line 10, in <module>
    from ds.ds_pipeline import DsVideo
  File "/home/t-yano/Projects/Gaze-Analysis-System/ds/ds_pipeline.py", line 20, in <module>
    import dscprobes
ImportError: libnvcv_faciallandmarks.so: cannot open shared object file: No such file or directory

Step reprocedure.

1. Run upgrade sudo apt upgrade
2. Install Deepstream-6.0.1 sudo apt install -y deepstream-6.0
3. Clone Git Repository & exec setup.sh

   git clone https://github.com/Ryoyo-NV/Gaze-Analysis-System.git
   git checkout -b jp4.6.2_ds6.0.1 refs/tags/jp4.6.2_ds6.0.1
   chmod +x setup.sh
   ./setup.sh

   The setup.sh shell has completed without any problems.

4. Start application

I have run the following

$ python3 run.py /dev/video0 --media v4l2 --cam-fps 10

I found libnvcv_faciallandmarks.so in the following directory

$ ls -la /opt/nvidia/deepstream/deepstream/lib/cvcore_libs/libnvcv_faciallandmarks.so
-rw-r--r-- 1 root root 670856  2月 14 23:52 /opt/nvidia/deepstream/deepstream/lib/cvcore_libs/libnvcv_faciallandmarks.so

It appears to be linked from dscprobes.so

Do you set LD_LIBRARY_PATH? https://github.com/Ryoyo-NV/Gaze-Analysis-System#usage export LD_LIBRARY_PATH=/opt/nvidia/deepstream/deepstream/lib/cvcore_libs:$LD_LIBRARY_PATH

Oh! I see!

This is my fault. Thank you for your advice. It worked!

close this issue.
