WebMar 11, 2024 · Times to create these are negligible as both cuDF and pandas simply retrieve pointers to the created CuPy and NumPy arrays. Still, we have so far only changed the import statements. The aggregation code is the same as we used earlier with no changes between cuDF and pandas DataFrames (ain’t that neat!) WebWhenever a data-type is required in a NumPy function or method, either a dtype object or something that can be converted to one can be supplied. Such conversions are done by the dtype constructor: dtype (dtype [, align, copy]) Create a data type object. What can be converted to a data-type object is described below: dtype object Used as-is.
