MemoryError when running Numpy Meshgrid

Question

I have 8823 data points with x,y coordinates. I\'m trying to follow the answer on how to get a scatter dataset to be represented as a heatmap but when I go

Answer 1

Your call to meshgrid requires a lot of memory -- it produces two 8823*8823 floating point arrays. Each of them are about 0.6 GB.

But your screen can't show (and your eye can't really process) that much information anyway, so you should probably think of a way to smooth your data to something more reasonable like 1024*1024 before you do this step.
