Summary
When dataset size is 5 and split ratio is [train=0.1, val=0.9, test=0.0], the splitter splits the dataset into [1, 3, 1] instead of [1, 4, 0].
This is a special case of incorrect partitioning due to the inexact round function of python.
So I fix this bug by ignoring subsets with a near-zero ratio.
