Hello,
is there any way how to downgrade HailoRT installation from 1.20.0 to 1.19.0? I need this because DeGirum PySDK works only with version 1.19.0 (for now) and with the new version it can’t find my HAILO8L device:

(degirum_env) pi@raspberrypi:~/hailo/hailo_examples/examples $ degirum sys-info
Devices:
  N2X/CPU:
  - '@Index': 0
  - '@Index': 1
  TFLITE/CPU:
  - '@Index': 0
  - '@Index': 1
Software Version: 0.14.3

Is there any way how to install the 1.19.0 version again? Thank in advance.

Hi @0LI
Please upgrade degirum to latest version 0.15.2 and it supports HailoRT 4.20 as well. We will soon update our readme to reflect support for latest hailort runtime.
