We have a type similar to this (a typed list) internally in pandas, although it is restricted to a single dimension and far from feature complete -- it only has .append and a .to_array() method for converting to a 1d numpy array. Our version is written in Cython, and we use it for performance re

Typed list in numpy would be a nice addition indeed and your cython implementation is nice (and small). In my case I need to ensure a contiguous storage to allow easy upload onto the GPU. But my implementation is quite slow, especially when you add one item at a time: >>> python benchmark.py P

Hi I would like to package python + numpy and our app for windows using pynsist in such a way that the user does not need to compile anything. Although pynsist made a package numpy did not start after installation due to some missing libraries. Obviously including the numpy directory is not eno
