Thanks for your time on this, @rbumm and sorry for the inconvenience.
The first thing I’d like you to check is the labels in the Task06_Lung dataset. What I see as labels in that dataset are actually lung tumors, not lungs and airway segmentation. See the following image:
I might be using a different version of that dataset.
I’m happy to meet on Teams/Zoom early Monday if you’re available.
Please let me know.
