Re: [Numpy-discussion] Runtime error in numpy development version

2011-05-24 Thread Jeffrey Spencer
Try removing numpy and openCV (and associated files) from /usr/local/lib/python2.7/dist-packages or wherever you originally compiled it too. Then rebuild numpy and openCV. Probably openCV was compiled with a different version of numpy at the time of compilation. Just a guess but removing and re

[Numpy-discussion] labeled axes

2011-05-24 Thread Craig Yoshioka
Hi all, I've read some discussions about adding labeled axes, and even ticks, to numpy arrays (such as in Luis' dataarray). I have recently found that the ability to label axes would be very helpful to me, but I'd like to keep the implementation as lightweight as possible. The reason I woul

Hi all, I have made my free solver interalg (http://openopt.org/interalg) be capable of solving nonlinear equations and systems of them. Unlike scipy optimize fsolve it doesn't matter which functions are involved - convex, nonconvex, multiextremum etc. Even some discontinuous funcs

[Numpy-discussion] filtering rows from a numpy.ndarray

I've read in a datafile to an ndarray with this command: data=np.genfromtxt('n.txt', delimiter='\t', dtype=[('paramname','S26'), ('study','S26'), ('class','S10'), ('count','f4'), ('average','f4'), ('sd','f4')) I would like to filter the array to only rows where paramname == 'bmi'. What would

[Numpy-discussion] 2D Fourier Transform with 1D functions

2011-05-24 Thread Goo Creations
Hi all I know there exists a function for Fourier transforming 2D : fft2 But I'm trying to understand how this function works. As far as I know, first a column based transform is done and then a row based transform. This is what I've created for a test: *test = np.array([[1+0j,2+0j], [3+0j, 4+0j
