[QUESTION]Question about wamup micro batch and model chunk in seq1F1B-I

[BLue1888]

Firstly, why warmup micro batch is Eq.6 in paper when interleave is enabled? That is not consistant with Figure 2 in paper. According to Eq.6, wamup micro batch num of last pp rank is 5, but is 9 in Figure 2.
Secondly, When seq1F1B - I is enabled, do we really not need to adjust the calculation of the model chunk according to the currently calculated chunk sequence?
