Re: [Visualpython-users] Python 2.5

[<ajs...@op...>]

I have began to look at this as well, at least for the 3.xxx tree.  I don't know
to what extent things are different for 4.xxx.

For 3.xxx, I don't think that the Numeric to Numpy script solves the issue 
because the integration with Numeric is via the boost.python library.

>From what I see there is another 3rd party code module that is used to 
enhance the boost.python support for Numeric and Numarray.

The good news that there has been a new release of this module quite 
recently specifcally shifting its focus to Numpy.  I have the details on my 
Linux box at home.
 
Is this in line with others' understanding?

I am not much of a C++ programmer, but this is something I might be able 
to get to the bottom of with some work.

But with Jonathan gone, I am suggesting that the vpython project 
should reach out to the wider Python community.

I think that the vpython project is (or should be) significant enough to 
that community as a whole - it certainly is to me - that the project should 
be able to elicit support from appropriate quarters.

I would be happy to help try to elicit assitance on this with some
consensus that doing so is appopriate.

I am copying this to the Python edu-sig list, where I had just 
raised the issue of Numopy incompatible this morning, and expressed 
some concern - with Bruce tied-up, and Jonathan gone - of getting 
the issue proper attention.
