It can confirm that actually works in Windows 11 native too.
Needed to install Python 3.9, then
git clone https://github.com/Project-MONAI/MONAILabel
$Env:PATH += ";C:\Users\rudol\MONAILabel\monailabel\scripts"
monailabel apps --download --name radiology --output apps
# modify segmentation.py by hand, add the lung and airway labels
monailabel datasets --download --name Task06_Lung --output datasets
monailabel start_server --app ./apps/radiology --studies ./datasets/Task06_Lung/imagesTr --conf models segmentation --conf use_pretrained_model false
I train 7-8 datasets, but all I get from auto segmentation is something like
where only the first segment carries the displayed data.
