Issue with Hailo-Python Package Installation (Possibly Related to Version 4.20)

I am trying step by step installation on the github, but when the
./install.sh is triggered after all the necessary steps,
the error occurs

I believe it occurs on requirements.txt file on hailo-apps-infra.git line
can you please check the github installation guide and see if it is still topical.

Reinstalled pi5 3 times now, and the problem still occurs, I believe it is guide related

I have the same issue.
In my case, after the Raspberry Pi with a working AI KIT module restarted, an error occurred stating that Hailo could not be found, and it failed to boot.
Since then, even after reinstalling Raspberry Pi OS, I keep encountering errors when running ./install.sh.
