Re: [Numpy-discussion] view takes no keyword arguments exception
Hi Jochen 2009/5/20 Jochen Schroeder cycoma...@gmail.com: I'm trying to help someone out with some problems with pyfftw (pyfftw.berlios.de). He is seeing an exception, TypeError: view() takes no keyword arguments This doesn't only happen when he uses pyfftw but also when he does the following: import numpy as np a=np.arange(10) print a.view(dtype='float') Traceback (most recent call last): File stdin, line 1, in module TypeError: view() takes no keyword arguments I he's on Windows and sees this error both with numpy 1.1.1 and 1.3. I'm a bit lost anybody have an idea what could be the problem? In the older versions of numpy, a.view(float) should work (float is preferable above 'float' as well), but I would guess that you are really looking for a.astype(float) Regards Stéfan ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

I don't want to change the code (This was just a short example). I just want to know why it is failing on his system and what he can do so that a.view(dtype='...') is working. I suspected it was an old numpy installation but the person is saying that he installed a new version and is still seeing the same problem (or does he just have an old version of numpy floating around).

Likely to be the second possibiity, the ghost of a previous installation. AFAIR, the keywords in .view were introduced in 1.2 or just after. A safe way to check would be to install numpy 1.3 in a virtualenv and check that it works. If it does (expected), then you may want to ask your user to start afresh (remove 1.1.1 and 1.3 and then reinstall 1.3 from a clean slate). My 2c.

I don't see this error on linux: In [3]: a.view(dtype=double) Out[3]: array([ 1., 1., 1., 1., 1., 1., 1., 1., 1., 1.]) What version of python do you have installed? Did try deleting the previous version of numpy from site-packages before install? Windows 32 or 64 bit? Etc.
