Boost.Python is difficult to understand, far more than SWIG. It may be
faster, but I don't think it is worth it ATM.
Binding C++ classes with SWIG is really simple.

Hi,

available from your website anymore. Is it possible for you to upload

Hi,
If the crash occurs in __init__, why do you give us more code ?
The crash can occur because you pass a char* to your library. This
char* is not managed by your library but by Python. This means that
when the constructor is finished, the string is freed and the char* is
not valid anymore.

Hi,
Python is a platform independent language, period. You can always
excute a Python script with python script.py. Now, with Windows, you
can execute the script by doucle-clicking on it. With Linux, it's
different, you have to use the shebang line to execute a script with
the correct interpreter.

Hi,
New style classes should be put as the default. This is what I did, based on
the principle that new classes were introduces in Python 2.2 and that we are
now at 2.5 and soon 2.6.
Tutorials that use old style classes may be old and perhaps won't be updated
ever. That's not a problem. Just tell

Hi,
You should send your question on the scipy user ML. If you use a distance
between objects, you can try the kmeans (implemented in scipy), if you use
similarities, you can change them to dissimilarities and use the same
function.

Hi,
I did not manage to build extension with distutils with Python compiled with
VS different than 2003. The need for 2003 was hard-coded in distutils.
You can try building extensions with VS2008 with Scons. This is what I do a
lot, and everything works fine as long as the interface does not use

Hi,
The error is generated because you are asking for a u8*, but the buffer is
not a u8*, perhaps a char* or even a void*. If you change the method

J'appelle ça les arguments nommés (parfois en anglais on parle de named
argument). Je pense que tu parles des arguments donnés dans les **kwargs,
c'est ça ?
On parle aussi d'arguments formels, par opposition aux arguments
positionnels lors d'un appel directement à une fonction :

Hi,
You should convert your data to numpy and make it 1D (for the moment, it is
3D) by calling the ravel() method. Then you can create your covariance

That doesn't imply not supporting file-object.
BTW, how is it possible to close the access to the database ? I deleted the
object but Winows tells me that someone is still holding the file.

Yes, but in this case, how can I use the DB that I downloaded from the net ?
If this is the way of using sqlite, it is still cumbersome as a lot of other
classes that work on files

want to use a temporary file that will be deleted at the end of my program.
For this, I wanted to use tempfile.TemporaryFile. The problem with Windows
