No such file or directory: 'colmap' error

Thanks for releasing this great work!

After following your (updated) installation guide and downloading the demo data, I tried running the demo 'exps/code-release/run_pipeline_demo_low-res.sh'.

After a few initial steps it crashes with

Hello my friend, I've encountered the same issue as well. Have you managed to resolve it?
