@olehb and all, I've updated this very good PR with some updated directory handling for test.py outputs. All test.py outputs will now be placed by default in a new runs/test directory, and if autolabels are requested using --save-txt then these will be placed in runs/test/autolabel, as per the screenshot below.

New runs of test.py will delete and reuse the same runs/test directory unless changed manually with --save-dir runs/test2 etc.
