Hi,
I am using python 32 bit version and I have a plot in which i am using rasterization,
Since i am using python 32 bit, i am getting Error of not casting my int64 data tp int32.
Data input my plot is accepting only while generating plot and using rasterization I am getting error.
I will really appreciate if you let me know how to solve this errror.
Error message is below:-
