I've built numpy on many different machines, including supercomputers, and
I have never used interactive setup. I agree with the proposal to remove
it.

In distutils there are three files that provide some interactive setup:
1. numpy/distutils/core.py
2. numpy/distutils/fcompiler/gnu.py
3. numpy/distutils/interactive.py
In Python3 `raw_input` has been renamed 'input' and python2 'input' is
gone. I propose that the easiest solution to th

I know there are two polyfit modules in numpy, one in numpy.polyfit, the
other in numpy.polynomial, the functionality you are suggesting seems to

A couple of days back, answering a question in StackExchange (

multipliers to fit a polynomial with least squares to data, making sure it
went through some fixed points. This time it was relatively easy, because

If we participate, it should be under the PSF organization. I suspect
participation for NumPy (and SciPy) largely depends on mentors being

Dear Scientist using Python,
EuroSciPy 2013, the Sixth Annual Conference on Python in Science, takes place in
Brussels on 21 - 24 August 2013. The conference features two days of tutorials
followed by two days of scientific talks that start with our keynote speakers,
Cameron Neylon and Peter Wang.
