I found this strange behavior:
(np113) [jensj at ASUS np113]$ python3
Python 3.5.3 (default, Jan 19 2017, 14:11:04)
[GCC 6.3.0 20170118] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> np.__version__
'1.13.0rc1'
>>> s = (27, 27, 27)
>>> x = np.ones(s, complex)
>>> y = np.zeros(s)
>>> y += abs(x * 2.0)**2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: Cannot cast ufunc add output from dtype('complex128') to
dtype('float64') with casting rule 'same_kind'
Works OK with s=(3,3,3).
