Train top-down id model

[Young-eng]

I want to evaluate tracking algorithms and get the metrics by training my custom datasets. I have trained top-down model with my datasets following the instructions in Tutorial, but when I try to train top down id model with my datasets, there are some errors during second stage : sleap-train multi_class_topdown.json 2024_0612_fish_512_train_labels.v001.pkg.slp

Error like this:

When I try to train top-down ID model with the example dataset: drosophila-melanogaster-courtship，I meet a different error during second stage:

There are no errors when training top-down model with these datasets. So I am not very clear about the training processing of top-down ID model, and do not find similiar problems in Disscusion. Are there any other methods that I can evaluate tracking algorithms in Sleap on my custom datasets? Thanks for your help!
