Hi, I've been using the lexsort and it is really nice. Much simpler and
faster than the implementation I had before. The only problem is it seems
to crash on strings.
Do I just need to upgrade numpy or is it a current bug?
In [2]: import numpy
nu
In [3]: numpy.array(['a', 'b', 'c'])
Out[3]:
array([a, b, c],
dtype='|S1')
In [4]: strArray = numpy.array(['a', 'b', 'c'])
In [5]: intArray = numpy.array([1,2,3])
In [6]: numpy.__version__
Out[6]: '1.0b5'
In [7]: numpy.lexsort((intArray,))
Out[7]: array([0, 1, 2])
In [8]: numpy.lexsort((intArray,intArray))
Out[8]: array([0, 1, 2])
In [9]: numpy.lexsort((strArray,intArray))
Segmentation fault (core dumped)
