[Train Metric Output] The number of classes in Average global foreground Dice is not matched

[hwanython]

Dear. Mr.Isensee,

Thank you for your incredible and outstanding work.

This is in regard to the outputs of metric in trainner.

I have a simple question:

I did consist 36 classes as confirming in "debug.json" under "~\nnUNetTrainerV2__nnUNetPlansv2.1\fold_0".

"classes": "[1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 3, 30, 31, 32, 33, 34, 35, 36, 4, 5, 6, 7, 8, 9]",

BUT I RAN THE TRAINNER, I GOT THIS PRINTS:

Average global foreground Dice: [0.788, 0.8464, 0.5243, 0.0, 0.2942, 0.0, 0.0103, 0.0, 0.0144, 0.0, 0.0078, 0.0882, 0.0, 0.358, 0.0874, 0.0022, 0.2592, 0.0, 0.0, 0.0, 0.0, 0.1054, 0.0044, 0.2917, 0.0, 0.0, 0.0, 0.0, 0.0, 0.002, 0.0021, 0.0005]

The list have 32 components, which means classes.

I expect the list have 36 length. Am I right?

WHAT DO I NEED TO CHECK FOR THIS?

Best regards, sir

Check it out here in the Trainer Online Evaluation

If the dice score is for some reason Nan it won't be printed. Which could be the case in your evaluation
