I was one of the people who responded to that poll, and I have to say that I fall into the category "they actually meant 'SciPy'…". I assumed that there would be an interface to numpy that would also support scipy. SciPy has a lot of packages that run various things like SVD very, efficiently because it does them in C. I need access to those packages. I also write my own algorithms. For those, I want to benefit from PyPy's speed and don't necessarily want to make the algorithms fit into numpy's array-processing approach. So, I NEED SciPy, and would like to also have PyPy, and I'd like to use them together rather than having to separate everything into separate scripts, some of which use CPython/SciPy and some of which use PyPy. In fact, my current code doesn't need NumPy at all except as the way to get to SciPy. So, I have to say, I am unhappy with the current PyPy approach to NumPy. I'd rather see a much slower NumPy/PyPy integration if that meant being able to use SciPy seamlessly with PyPy. -- Gary Robinson CTO Emergent Discovery, LLC personal email: gary...@me.com work email: grobin...@emergentdiscovery.com Company: http://www.emergentdiscovery.com Blog: http://www.garyrobinson.net _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
