I have a DF that I want to use Groupby + Shift. I can do this in pandas, but I cannot do it in cuDF because it is not implemented yet: see the issue Issue #7183. The feature request was long ago, so it seems like they will not implement this in the near future. Is there any alternative way?
UPDATE: RAPIDS just finished merging groupby.shift() into cudf.
Please try it out in the 21.06 nightlies!
