[Visualpython-users] problems with faces_ demos on 64-bit hardy

From: anders <and...@gm...> - 2008-06-17 05:59:13

hi all,
I'd like to report some problems that show up with both the faces_xx.py 
demos with visual-3.2.9 (I'm using Python 2.5.2 on 64-bit Ubuntu 8.04)

I get mostly garbage:
http://imagebin.org/21126

the other demos work fine, so I'm thinking my opengl hardware/drivers 
are ok.

googling around it seems that this may be a problem with numpy on 64-bit 
machines? When trying to use the faces object I get the error message 
quoted below.

anyone else seeing this too? any suggestions?

regards,

AW

With visual-3.2.9 you're using the older Numeric, not the newer numpy. 
It does seem plausible that there could be some problems with Numeric in 
a 64-bit environment, since it was developed and debugged long before 
64-bit computers were generally available. I don't know what would have 
to be changed to get around this problem (and I myself don't have access 
to a 64-bit machine).

It might be interesting to see what happens with the beta version of 
Visual, since it is based on numpy.

Yes! I downloaded visual-4.beta26 and installed all the dependencies that
./configure insisted on (including numpy), then installed with 'sudo make
install', and now all the demos work fine.

related to version numbers, what does this number mean?
>>> visual.__version__
'1.0.4'

I can't find where this comes from in the code, after searching
everywhere for "version". If you instead invoke visual.version you'll
get (4, beta26).<br>
