Hi Devanshi,
> Gridded2DSet: samples do not form a valid grid
Each box of the grid must be convex and non-overlapping with other boxes,
or you will see this message.
If you need further assistance, please post a complete code example
somewhere (I recommend as a project on GitHub), so that we can compile and
run it, and hence help you debug further. Just posting a code fragment is
not enough because you did not include your actual samples array. In
general, I would advise doing everything you can to make it easy for us to
help you.
Regards,
Curtis
