heart chamber task hangs when saving segmentations

[lukasvaz]

I am currently running experiments using the heart chambers task on a set of NIfTI files (using python API). It works fine for most cases, but for files larger than ~ 200 MB, it hangs while saving, sometimes for at least 20 minutes (or sometimes just crashes).I tried compressing the files to .gz but im still getting the problem with the exact same files. Are there any solutions to this issue? or are just hardware constraints ? im running it on ubuntu 22.04.

This typically happens when you run into RAM limits. You need more RAM or a smaller image.
