So do none of the stages work?

And which command did you run? Can you post it exactly?

Also you have written the local variable 2 times in your post. Which is it? And are you on Windows or Linux?

path: local
paths:
   - local: /home/anne/Anne/data/airway_vida_test/A2019RR46/   # <- this one?
   - local: G:\Airway\A2069BH51\     # or this one?

I am using windows, where the local variables are used second, and the npz file in stage 01 is converted by its own method. In the second step (airway/image_processing/remove_all_0_layers.py), "ERROR: No patient data path supplied"

I cannot reproduce the error. What happens if you run the tutorial with airway tutorial? It should create a sample patient, can you then run airway stages 2 --path example? Does that work?
