I tried running the Neuro LGG PreOp segmentation model in Raidionics slicer extension, but when clicking on Run the segmentation, the method never finishes and the following error shows in the python console:

[Python] Traceback (most recent call last):

[Python] if current\_class not in list(RaidionicsLogic.getInstance().output\_raw\_values.keys()):
