(2) In RaspberryPi5, i made venv and install object_detection requirements.txt

(3) when run command “./object_detection.py”, the error occur

Traceback (most recent call last):

    import hailo_platform.pyhailort._pyhailort as _pyhailort
ImportError: libhailort.so.4.21.0: cannot open shared object file: No such file or directory

(4) I checked pkg files, they already installed

>> dpkg -l | grep hailort   

ii  hailort                               4.20.0-1                            arm64        HailoRT
ii  hailort-pcie-driver                   4.21.0                              all          Hailo PCIe driver and firmware
ii  python3-hailort                       4.20.0-1                            arm64        HailoRT Python API, which wraps the runtime library

What should i do :melting_face:?

Hey @JBK ,

For RPI you should install the hailo driver and hailort using the hailo-all package , to do so please follow this guide : https://www.raspberrypi.com/documentation/computers/ai.html#getting-started

You should first remove all of the current hailo packages and then run the installation above , to clean all hailo packages please run these commands :

dpkg -l | grep hailo
sudo apt-get remove --purge -y hailo* libhailo*
sudo apt-get autoremove --purge -y
sudo apt-get clean

Thank you for your help

I remove exist package and re-install 4.20, it worked
