I have run the test and did not see the error that you are reporting. I have attached the example with an image to this comment. Please try with the new files and see if you have the same issue.

Hi, I tried your example, but from message below I can't load libvx_nn.so. Also I added lib path libvx_nn.so to LD_LIBRARY_PATH, but this didn't help.

@peter-zigo-nxp I have attached 2 scripts which will setup the deps for this project and build the project and installs.

Please follow the steps below after you unzip the files in the scripts.zip

• Step 1: Run the setup.py script

  python setup.py -s [sudo password] -d [setup directory - optional] 

• Step 2: Run the build.py scipt

  python build.py -s [sudo password] -d [build directory - optional]

• Step 3: Set Library path

  .  rocmrc

• Step 4: Run the example

  runvx example1.gdf

  scripts.zip

@peter-zigo-nxp it looks like you are not building the vx_nn project due to dependency failure. Please check if you have libvx_nn.so in the lib folder, if not just follow the instructions in the previous comment.

@peter-zigo-nxp I am closing this issue as it is not an amdovx-modules bug. If you still have build issues please open a new bug with the deps failure.
