Hello.
I'd appreciate if the NumPy team could provide an MSI installer
for Python 2.7.
Thanks,
Ram Rachum.
You're not the only person who would like this - it was discussed
here just 9 days ago, thread title "A release for python 2.7?", and
the conclusion was we'd have to wait for Numpy 1.5, probably in
August.
It seems that building from the 1.4.x branch works out of the box, so
at least a numpy msi should be straightforward,
Binaries built from the numpy 1.4.x branch do crash on Python 2.7
because of this: http://projects.scipy.org/numpy/ticket/1345. The fix is
easy to backport (attached). Until yesterday another reason not to
release numpy 1.4.1 binaries for Python 2.7 was the projected use of
PyCapsule instead of PyCObject in numpy 1.5+.
