I have lightly adapted @celestial-33 's wonderful Mac version to work in Linux. I haven't provided advice for installing the requirements, however (not convinced I'd do a good, broadly applicable job).

I forked and updated the script a bit: https://gist.github.com/aidv/05779c76401ae55ee6b227ee0c1e47f9

Apparently AMD GPU's are very wonky with COLMAP/GLOMAP, so forcing CPU usage is better.
