[Numpy-discussion] numpy array casting ruled not safe

[Dinesh Vadhia]

This was originally posted on SO (https://stackoverflow.com/questions/28853740/numpy-array-casting-ruled-not-safe) and it was suggested it is probably a bug in numpy.take.

Python 2.7.8 |Anaconda 2.1.0 (32-bit)| (default, Jul  2 2014, 15:13:35) [MSC v.1500 32 bit (Intel)] on win32

>>> import numpy
>>> numpy.__version__
'1.9.2'

>>> a = numpy.array([9, 7, 5, 4, 3, 1], dtype=numpy.uint32)
>>> b = numpy.array([1, 3], dtype=numpy.uint32)
>>> c = a.take(b)

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    c = a.take(b)
TypeError: Cannot cast array data from dtype('uint32') to dtype('int32') according to the rule 'safe'
