Fast NumPy array functions written in Cython

Project description


Bottlechest is a fork of bottleneck (, specialized for use in Orange (

Moving window functions, several other functions and all optimization of 3d arrays are removed to reduce the size of the library. New functions are added as needed.

NumPy/SciPy median, nanmedian, rankdata, ss, nansum, nanmin, nanmax, nanmean, nanstd, nanargmin, nanargmax
Functions nanrankdata, nanvar, replace, nn, anynan, allnan, nanequal

For other documentation, including a simple example and comprehensive set of benchmarks, refer to the original project.
