Is the warning message produced by the test script below an issue I need to address if I am to use the numpy and scipy libraries? The script below gives me the warning below on both windows 7 and vista Thanks for your time Ben
Python Script
#!/path/to/python import re, string, sys from numpy import * import scipy.weave print "Hello, World!"
Warning Message C:\Python26\lib\site-packages\scipy\io\matlab\mio5.py:90: RuntimeWarning: __builtin__.file size changed, may indicate binary incompatibility from mio5_utils import VarReader5
Hello, World!

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.

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.

Hmm, missed this one, also can't reproduce it on either XP or OS X with the same numpy/scipy versions. If these warnings are platform-dependent shouldn't that be considered a Cython bug?
Related commits are r6331 and r6512 in scipy.

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

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?
Cheers, Ralf

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. And more: Your email address below has to be valid. An authorization email will be sent to you after posting. You have to reply to that message to confirm that you exist. After you've confirmed your existence, the message will then be forwarded to the mailing list.
