[Numpy-discussion] ValueError: low level cast function is for unequal type numbers

2012-12-07 Thread Christoph Gohlke
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')]))

Aha, thanks for the clarification. I've always been surpassed that NumPy doesn't ship with a copy of CBLAS. It's easy to compile --- just a thin wrapper over BLAS, if I remember correctly. -Brad On Friday, December 7, 2012 at 4:01 AM, David Cournapeau wrote: On Thu, Dec 6, 2012 at 7:35

One way of fixing this I'm sort of itching to do is to create a pylapack project which can iterate quickly on these build issues, run-time selection of LAPACK backend and so on. (With some templates generating some Cython code it shouldn't be more than a few days for an MVP.) Then patch NumPy

Oh, never mind, I guess they *only* allow image files. So, uh, no test data files, but if we have any lolcats in the trac attachments, we can migrate those. On Fri, Dec 7, 2012 at 9:00 PM, Nathaniel Smith n...@pobox.com wrote: Heh, looks like we did the trac migration about a month too soon...
