Howdy dlib error - No module named 'dlib'

[Hamster1962]

My Howdy was working perfectly until a large update last night. Lots of Python and Camera type updates. Now when i try and use Howdy i get the error :-

Traceback (most recent call last): File "/lib/security/howdy/compare.py", line 18, in import dlib ModuleNotFoundError: No module named 'dlib'

Restoring a Snapshot solves the issue until the next update is run

I've searched for similar issues already, and my issue has not been reported yet. Yes

Linux distribution = Garuda Linux based on Arch with KDE Desktop Kernel 6.2.13 zen-1-zen

Howdy version (sudo howdy version): Howdy 3.0.0 BETA

Please help

Did you rebuild the relevant python packages after system update?

In my case (also yesterday with arch updates), I have to rebuild some relevant packages, though not dlib.

Some discussions on how to find out all packages need rebuild:

• https://github.com/Jguer/yay/issues/1671
• https://www.reddit.com/r/archlinux/comments/k56ydd/updating_all_aur_packages_dependant_on_python/

@Hamster1962 try sudo pip install dlib

[Hamster1962]

I left it for 24hrs. Just as an update broke it, so another update fixed it. H

Magic! :smile: :magic_wand:

this worked: but in a bit more aggressive version for new versions of ubuntu/pip/python:

sudo pip install dlib --break-system-packages

please take into account that this may break existing installation of the system, so it is maybe a bit risky for your system

So, in my case, after check my error I found that C compiler was not found, I had to install build essentials with sudo nala install build-essential (or it can be by sudo apt install build-essential)

Here was my error at install dlib:
