Hi Dan,
I have recently created an AMI for running python processes.
I recommend using the ubuntu server ami's provided by http://alestic.com/.
Alestic is a well known provider of public AMI images. I think this is
exactly the place you want to start from; anything you need is an apt-get or
Hi,
I have added a couple of utilities for floating point comparison, to
be used in unit tests mostly, and would like some comments, especially
from people knowledgeable about floating point.

Hi,
I am trying to load a tsv file using numpy.loadtxt:
data = np.loadtxt('data.txt',delimiter='\t',dtype=np.float)
And I get:
-
/usr/lib/python2.6/site-packages/numpy/lib/io.pyc in loadtxt(fname, dtype,
comments, delimiter, converters, skiprows, usecols, unpack)

Have you tried the numpy.fromfile function? This usually worked great for
my files that had the same format than yours.

Hi,
I'm getting (to me( very mysterious NaNs when doing matrix
multiplication with certain (randomly generated) data:
In [52]: a.shape, b.shape, i, j
Out[52]: ((22, 1000), (1000, 22), 0, 16)
In [53]: np.dot(a, b)[i,j]

In [54]: np.dot(a[i,:], b[:,j])

good point -- fromfile() can be much faster for the simple cases it can
handle.
