Hailo_invalid_driver_version (76)

General

Hi there,
I followed all steps for running the detection.py example which didn’t work in the first step and then something was generally messed up :confused:
I’m currently having Driver version 4.19.0 and the library version is 4.18.0
therefore, hailortcli fw-control identify is giving me this output:
[HailoRT] [error] CHECK failed - Driver version (4.19.0) is different from library version (4.18.0)
[HailoRT] [error] Driver version mismatch, status HAILO_INVALID_DRIVER_VERSION(76)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_INVALID_DRIVER_VERSION(76)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_INVALID_DRIVER_VERSION(76)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_INVALID_DRIVER_VERSION(76)
[HailoRT CLI] [error] CHECK_SUCCESS failed with status=HAILO_INVALID_DRIVER_VERSION(76)

I tried anything and removed every hailo-package plus the driver but when re-installing hailo-all i still keep getting this error.
Is there away to purge anything or downgrade the drivers to 4.18.0 again?

PS: I tried this tutorial:

which upgraded my driver and messed up anything

Hey @Darklord_Ice,

Welcome to the Hailo Community!

To resolve your issue, let’s perform a clean reinstallation of the Hailo software stack:

  1. Remove Existing Hailo Packages
sudo apt-get purge --remove 'hailo-*'
  1. Clean Up Hailo Directories
sudo rm -rf /opt/hailo /usr/local/hailo /usr/share/hailo ~/.hailo /lib/firmware/hailo
  1. Remove Hailo Kernel Driver
sudo rmmod hailo_pci
sudo rm -rf /lib/modules/$(uname -r)/kernel/drivers/misc/hailo_pci.ko
  1. Verify Removal (Optional)
find / -name '*hailo*' -exec ls -ld {} \;
  1. Install Fresh Copy
sudo apt install hailo-all

Let me know if you need any clarification or run into issues!
