I am trying to represent missing values and here is the code:
ac = hl.if_else(hl.len(nisc[mt.row_key].info.AC) >= mt.a_index, nisc[self.mt.row_key].info.AC[mt.a_index - 1], hl.missing(hl.tint32))
But I need to run it with
Hail version and
hl.missing is absent in it. What could I use instead of it? Is there any function that is compatible between the versions?
