missing libyolo_hailortpp_postprocess.so

[fuxifex]

hi,
i did a complete fresh install on my Pi5, following the Tutorial.
Anything seems correct but i can’t run the detection.py script - getting this error:

Showing FPS
Could not load lib /home/pi/hailo-rpi5-examples/basic_pipelines/…/resources/libyolo_hailortpp_postprocess.so: cannot open shared object file: No such file or directory
Cannot load symbol: /lib/aarch64-linux-gnu/gstreamer-1.0/libgsthailotools.so: undefined symbol: filter
Speicherzugriffsfehler

Any ideas what’s wrong / where to get the missing file libyolo_hailortpp_postprocess.so?

Same issue.

./compile_postprocess.sh

Hm...I have exactly the same problem..

Ditto - experiencing the same problem...

I was able to get my RPI-5 / HAILO detection pipeline to function appropriately using these procedures:
https://github.com/hailo-ai/hailo-rpi5-examples/blob/main/doc/basic-pipelines.md#installation

I have not yet determined why other "Quick Start" procedures generated the error described in this thread.

Hi The missing post process can occur if the post processes were not compiled correctly. It should be done as part of the install flow. You can do it manually by running ./compile_postprocess.sh
