Hello,
the following code using np.object_ data types works with numpy 1.5.1
but fails with 1.6.2. Is this intended or a regression? Other data
types, np.float64 for example, seem to work.
In [1]: import numpy as np
In [2]: np.array(['a'], dtype='O').astype(('O', [('name', 'O')]))
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
<ipython-input-3-f4a62241f13c> in <module>()
----> 1 np.array(['a'], dtype='O').astype(('O', [('name', 'O')]))
ValueError: low level cast function is for unequal type numbers
In [3]: np.array([16], dtype='d').astype(('d', [('name', 'd')]))
Out[3]: array([ 16.])
