Hello, World!

Which numpy and scipy versions are you using? e.g. scipy.__version__ np.__version__

This looks like a warning from cython, but the versions are still binary compatible, and there shouldn't be any problems. (with all numpy except 1.4.0 and 2.x in repository)

It's a safe combination, and the cython warning has no effect.

(Maybe a disclaimer: There's always a chance that new things show up, but I haven't heard of any problems.)

Just a side comment: ActiveState is distributing (since June) "New packages for data centric financial modeling and scientific computing applications (available in ActivePython Business, Enterprise, and OEM Editions): * NumPy: The fundamental library needed for financial and scientific computing with Python * SciPy: A suite of scientific tools for Python, depends on the NumPy library * matplotlib: A Python numerical plotting library " because of changes in US financial regulation. So maybe we get some additional testing out of it. Josef

Didn't Ralph catch the warnings on import for the released binaries? Maybe he missed one. Also, I don't recall seeing seeing that one before, not that it is necessarily a problem.

matlab\mio5.py:90: RuntimeWarning was reported during scipy 0.8 rc2 testing I don't know which warnings were silenced Josef

Hello, Got the same error, working on windows 7, 64 bit... Does this help? Is there a solution available? Luc

It's not an error but a harmless (although confusing) warning message. You should be able to filter it by adding the following to scipy/__init__.py:

import warnings warnings.filterwarnings(action='ignore', message='.*__builtin__.file size changed.*')

Can you check if that works for you?

Worked on my system! osx 10.6.5, python 2.6, numpy 1.5.1, scipy 0.8! Need to add useless stuff to satisfy the condition that there be more newtext than quoted. Argh.
