Bottleneck is a collection of fast NumPy array functions written in Cython. It contains functions like median, nanargmax, move_median, rankdata, partsort, replace, anynan. The sixth release of bottleneck adds four new functions and, thanks to Dougal Sutherland, now supports Python 3.2. New functions: - replace(arr, old, new), e.g, replace(arr, np.nan, 0) - nn(arr, arr0, axis) nearest neighbor and its index of 1d arr0 in 2d arr - anynan(arr, axis) faster alternative to np.isnan(arr).any(axis) - allnan(arr, axis) faster alternative to np.isnan(arr).all(axis) Enhancements: - Python 3.2 support (may work on earlier versions of Python 3) - C files are now generated with Cython 0.16 instead of 0.14.1 - Upgrade numpydoc from 0.3.1 to 0.4 to support Sphinx 1.0.1 Breaks from 0.5.0: - Support for Python 2.5 dropped - Default axis for benchmark suite is now axis=1 (was 0) Bug fixes: - #31 Confusing error message in partsort and argpartsort - #32 Update path in MANIFEST.in - #35 Wrong output for very large (2**31) input arrays download   http://pypi.python.org/pypi/Bottleneck docs   http://berkeleyanalytics.com/bottleneck code   http://github.com/kwgoodman/bottleneck mailing list   http://groups.google.com/group/bottle-neck
