Hi,
I'm getting a SEGV for boolean indices to a multi-dimensional array (numpy ver
1.4.1). Is this a known problem? Code and backtrace below.
Thanks,
Geoff
import numpy
a = numpy.ones((1,1))
a[a>0]

It is CentOS, heavily customized, I am sure, for this

OK, installing from source solved the problem (and so di

Hi All,
Sorry if this has been documented or discussed already, but my searches have
come up short. Can someone please recommend a way to setup both Cython and
Fortran extensions in a single package with numpy.distutils (or something
else)? E.g.:
from numpy.distutils.core import setup, Extensi

Yes. I was one who asked recently. I've not seen easy_install nor pip
mentioned on the website nor INSTALL

arr[None,:] is a lot cleaner in my opinion, especially when using
"numpy" as the namespace.

If you use LaTex and Mac OSX, I recommend BibDesk:

Quite nice, and open-source.

This does not exactly answer your question, but you can use the dtype
string representation and positional parameter to make things nicer.
For example:
a = numpy.array( [1.0, 2.0, 3.0], 'f' )
instead of
a = numpy.array( [1.0, 2.0, 3.0], dtype=numpy.float32 )
