[Visualpython-users] Finally we have problems with vpython, Numeric, Numpy, NumArray

[<jam...@fd...>]

Hi all, As I suspected, finally we have a complete disorder.

If you get a new computer using win32.

Install Python 2.5.1
Install vpython,
vpython does not work because there is no Numeric module installed.

If you go to the page of Numeric Numpy, you see that all versions of the 
old Numeric for python 2.5 where deleted and there is no version of the 
old Numeric for Python 2.5

So, you must install the New Numeric wich is Numpy.
But it seems that vpython does not work with this version.

The unique option is to use numarray, but numarray has been discontinued 
an will no longer be mainained an updated.

So, should we do ?

regards.

I don't understand. The VPython installer VPython-Win-Py2.5-3.2.10.exe 
for Python 2.5 available at vpython.org includes Numeric. This installer 
was made last fall to get around precisely the problem you describe, the 
lack of a separately available Numeric. I just verified that this works 
as intended, though admittedly with Python 2.5 which I happen to have on 
my computer, not Python 2.5.1 (but I would be shocked if that made a 
difference).

If you look in c:\Python25\Lib\site-packages you should see a folder for 
Numeric as well as a folder for visual.

I would suggest using the Add/remove control panel to remove VPython and 
re-install it, though I don't know why that should be necessary nor why 
it should help the situation.

Has anyone else had a related experience?

Incidentally, one of the big contributions made by the late Arthur 
Siegel was to change Visual to use numpy instead of Numeric in the beta 
version of Visual.

Hi, Bruce
This is what I get.
I have removed and resintalled vpython but the problem still remains.

Also, I cannot find any Numeric for python 2.5 !!! It seems that i was 
deleted in order to force people to migrate to the new Numpy.
Bests.
jose.

Re: [Visualpython-users] Finally we have problems with vpython, Numeric, Numpy, NumArray

[Bruce S. <Bru...@nc...>]

Thanks for showing the VPython installer page. The reason that Numeric 
doesn't show up as a choice is because it is BUILT INTO the VPython 
installer. You don't need to install Numeric separately, and no choice 
is offered.

The reason why Numeric is built into the VPython installer for Python 
2.5 is precisely because Numeric itself has been made unavailable, to 
force people to migrate to numpy, as you say. As a stop-gap measure, 
last fall I compiled Numeric from the still-available source code and 
bundled it into the VPython installer for Windows, so that there would 
be a VPython for Python 2.5 on Windows.

The long-term solution is to get the beta version of VPython working on 
Windows (and Mac), with its reliance on numpy.

So I say again, after running the VPython installer you should see in 
c:\Python25\Lib\site-packages a folder for numeric as well as a folder 
for visual. Do you see both of these folders? Then it's a separate 
question why you're unable to run.
