Hi Andrew -
I had problems with Numeric 24.0b2 and visionegg.
Creating a mask results in an integer error:
>>> mask = Mask2D(function='circle',
... radius_parameter=300,
... num_samples=(512,512))
Traceback (most recent call last):
File "<stdin>", line 3, in ?
File
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/
python2.3/site-packages/VisionEgg/Textures.py", line 1234, in __init__
xx = Numeric.outerproduct(Numeric.ones((1.0,cp.num_samples[1])),
File "/Library/Python/2.3/Numeric/Numeric.py", line 581, in ones
a=zeros(shape, typecode, savespace)
TypeError: an integer is required
I think the problem is that Numeric.ones is not supposed to accept a
float as a shape argument, however, previous versions would accept this
behavior:
http://sourceforge.net/mailarchive/message.php?msg_id=11551712
replacing offending lines in Textures.py containing the string:
Numeric.ones((1.0,cp.num_samples[0]))
with
Numeric.ones((1, cp.num_samples[0]), 'f')
should make the code behave as is expected on all versions of Numeric.
I'm not sure about the rest of visionegg - there may be more code that
does this.
Mark
