The results of the reproduction are reported to “nan”

The academic level of your paper is very high, and I reported a lot of "nan" in the IVT results column during the reproduction process, is this normal, thank you

Thank you for your comments. The occurrence of NaN is normal. The ivt category being NaN indicates that this category has no corresponding samples in the test set. The final result is obtained by averaging the non-NaN categories. Similar cases have also been observed in previous works, such as RDV and RiT.
