I suspect you need to force-include the numpy/core/_internal.py file by

That module is only

solution to this question that works with numpy.
You can also view the array using fields and then sort (which will do
lexicographic ordering) and convert the result back to the original view.
Something like this:
a = array([[5,2],[1,3]])
dt = a.dtype
g = a.view([('',dt),('
a=data+row

This is exactly the kind of thing NumPy (http://numeric.scipy.org) is
ideal for. If that's of interest to you, then I can offer particular
suggestions...

ut 4 decimal places.
You need to use the tostring() method and write that out in binary form.
flon = open(lon_file,'wb')
flon.write(your2darray.tostring())
of course you will need to manage byte-order issues if you will be
transferring this file to a different kind of processor.
Alternatively, with new NumPy there is a tofile method that you can use
to write in either ascii or binary form.

No. They are two separate projects. Scientific Python is still

The developers for NumPy are also the developers for SciPy (for the most
part).

Thanks to Tim for spreading some light on the issue. There will no

Hopefully, with time the confusion will fade as more people use NumPy
and any remainging issues get resolved.

We are pleased to announce the release of NumPy 1.0.2

objects, string, unicode, and general C-struct

You might try something like this.

This is the source of the remaining errors
On my system the "png.h" file comes from a libpng3-devel rpm
Perhaps you need to use apt-get to obtain the development package for png.
