Can't add a face model

[JakeTaka]

I was able to install with Linux Mint just fine. When I tried to run sudo howdy add as per the setup isntructions, I ran into an issue. Here is the full text:

sudo howdy add
No face model folder found, creating one
Adding face model for the user jake

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

Linux distribution (if applicable): Mint 21.3

Howdy version (sudo howdy version): 2.6.1

Closing issue as I found another post detailling this issue as well. The workaround there worked well for me and I will post links to the original issue and post the content of the workaround below in case anyone sees this one first.

Original issue: Link
Workaround: run sudo pip install --upgrade numpy==1.26.4 (thanks @simonporter007)
