Doesn't work, complaining that the object has no __buffer__ attribute.
Digging into the numpy c code it seems numpy doesn't even support the
buffer protocol but only the deprecated (old) one
http://docs.python.org/c-api/objbuffer.html .
At least there is nowhere a PyObject_CheckBuffer() call but

Hi There,
I am very new to numpy and have really only started investigating it as
one of my students needs some
Hi There,
Thanks for the responses.
At this point I would settle from just being able to install matplotlib. Even
if some of the functionality isn't present currently that is fine.
I'm afraid my knowledge of Python falls down about here as well. I installed
Python 3.2.2 via the installer
What version of numpy are you using? IIRC the new buffer protocol has
been supported since numpy 1.5.

Hi,
If I remember correctly, float is a double (precision float). The precision
is more important in doubles (float64) than in usual floats (float32). And
20091231 can not be reprensented in 32bits floats.

I've looked at the source code of numpy 1.6.1 and couldn't find the
respective code... I guess I must be doing something wrong but there
really was no call to PyObject_CheckBuffer() ...
Look for PyObject_GetBuffer
The problem is I don't
