Shotwell – How to Install Shotwell with Face Detection in Ubuntu 18.04

opencvshotwell

I'm transitioning from Google Photos and I really liked Shotwell's features. However, face detection/recognition is very important to me because of how I manage my photos. I viewed this blog post that apparently shows how to do it, but it's very vague IMO since I'm not exactly an expert in this area. I tried doing the meson build but there were a ton of dependencies that I manually installed (maybe wasn't supposed to do that?) and one of them messed up my apt system (I ended fixing that by removing all other software in the Software app and doing a dist-upgrade which removed unnecessary packages and dependencies).

Is there a more step-by-step guide to doing this? I really like Shotwell but I must have the face detection feature (I know that it is in beta, but I saw a video that proves it works).

(I know I could use digiKam but I really like Shotwell!)

Here's what you could do:

# Downloads will be our workspace
cd ~/Downloads

# prepare the terrain by removing unwanted divs
sudo apt remove shotwell gir1.2-gexiv2-0.11 -y
# install dependencies (takes about 30 mins to complete)
sudo apt install unzip meson valac libgphoto2-dev libgudev-1.0-dev \

Note: my post is WIP and edits will be accepted.

Update: I'm losing hope, I can't figure out how to get an install of opencv and how to get the mentioned DNN models from OpenFace.
