Hi @divyanamei,  
Creating grids with PyGMT is an art! Basically, you have to think a bit about the distribution of your input data and the resolution you want. As @Joaquim mentioned (back in 2020 ! and beyond…), this message means “that the limits of your grid are not divisible into an integer number of grid increments (plus a small tolerance).” You MUST use grdedit -A, but before that, think a bit about the grid limits and the desired increment.

If you search in the forum, there are a few discussions about this. I think it can help you to fit a solution for your problem.
