If you get errors like "Type geography not found" from Postgres when
|
||||
running distance based searches, this is the likely culprit.
|
||||
|
||||
### Face Detection
|
||||
|
||||
Fedora: `dnf install python3 python3-opencv opencv-data`
|
||||
|
||||
Debian: `apt install python3-opencv opencv-data`
|
||||
|
||||
If you get an error like:
|
||||
|
||||
> facedetect: error: cannot load HAAR_FRONTALFACE_ALT2 from /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml
|
||||
|
||||
Check whether the correct path on disk is actually /usr/share/opencv4 instead of /usr/share/opencv.
|
||||
One solution then is to symlink the path correctly.
|
||||
|
||||
## Building the App
|
||||
|

This app is written in Go: [go.dev](https://go.dev). You can probably
