Pretrained ResNeXt-101 Class -> ID ?

[Madave94]

Which classes corresponds to which ID in the pretrained network (e.g. author = ID 8)?

I tried the three different data subsets, but to me it looked like none of the categories and their corresponding ID matched the order of the annotations. The three different subset train, valid and test have different ID/Class category ordering.

For example ID 2 has the class section assigned in the training set, while in valid its equation and in test its reference.

Is there some additional information regarding this?
