Hi All. I am trying to run the TAPPAS examples. I tried multiple of them. Most of them get the error message: WARNING: erroneous pipeline: no element “hailofilter”

I am using an x86 board Tiger Lake i7 with Hailo8.

Trying to run the examples with the provided tappas container.

Any suggestions?

Thanks
Alex

Here is the example I am trying and the output I am getting:

Figured it out, had to run: hailo@alex-cExpress-TL:/local/workspace/tappas$ ./scripts/gstreamer/install_hailo_gstreamer.sh to get it working.

scripts folder has a few installation files,

  1. Did you install all of them?
  2. did it matter the order which you install them? In terms of dependencies
