PyGeo

[L]

has anyone successfully installed PyGeo under python 2.7 (prefer ubuntu
10.04) ,
the site says

http://www.wspiegel.de/pymaxima/index_en.html

"Note: The installation of PyGeo work's only under Python 2.4 (The
further development of pygeo seems to be stopped)"

is this to do with re-org of site-packages, dist_packages etc.

any help most appreciated.

TIA

I don't know. I haven't tried. Maybe somebody else here has, but don't count
on it. Have you tried it? If not, then why not? Try it. Maybe it just works.
As far as I know, distutils haven't changed much, carefully avoiding any
changes that could break packages.

I think it's entirely possible that the web page author claiming "the
installation" doesn't work was referring only to the Windows installer.

Have fun,
Thomas

I have tried it and as soon as you try any of the examples in the
examples dir it cannot find numpy etc....

I have manually move the pygeo dirs and contents to
/usr/lib/python2.6/dis-packages,

(this is the directory where numpy, numeric and scipy were installed
when using synaptic )

made sure that read and write permissions set for ALL FILES and
DIRECTORIES to RW using sudo chmod 777

any ideas.

Wait -- did you just try to use pymaxima, or did you properly (try to) install
the dependencies?

You need VPython. It's in the ubuntu archives.
http://packages.ubuntu.com/lucid/python-visual

And then you need to download and install pygeo.
http://pygeo.sourceforge.net/download.html
It probably uses distutils, so you'd extract the source archive and run
sudo python setup.py install

If THAT gives you any errors, then please come back here, with the exact error
messages. If it works, then PyGeo should be installed. If it still doesn't
work, then there's certainly a chance it won't work, but you can still ask
here for help, with the exact error messages, so we have something to build
upon when trying to figure out what's wrong.

No, I have not tried pymaxma ( I have maxima and wxmaxima install via
synaptic, tested and all works OK)

yes, that is what I did for install.

Vpython already install via synaptic, ran a number of examples and all
produced the expected output.

also the PyGeo readme text mentions Numerical python (I think it means
Numeric, but I also have NumPy installed)

to install i did the following steps
PyGeo
downloaded form sourceforge
tar xvfc PyGeo-1.0a1.tar.gz
cd PyGeo-1.0a1
python setup.py install

NO ERROR MESSAGES ecountered

IT DID NOT WORK coplaing about the NUMERIC module

I repeated the install and issued the parameter to 'python steup.py
install.....) to force the directory name to be the same where the other
python modules are (see listing below)
NO ERROR MESSAGES ecountered


Note what I did to ensure permissions etc (see my second post for
directories etc)

install successful, but running the example from ...examples/real/
using IDLE

I get

THAT's the information I was waiting for. So, it looks like everything is
working together, except that the visual module appears to have changed
somewhat since PyGeo was written. Importing "visual" within PyGeo appears to
have worked, but "visual.ui" doesn't exist.

After having a brief look at the documentation, I found no mention of a "ui"
object, but there appears to be visual.display -- so, if you wanted to port
the package to the latest VPython, that would be a place to start: replace
"visual.ui.display" with "visual.display", and try again. And the fix the next
problem, and so on, until it works, when you can send a patch to the old
maintainer.

[Giacomo Boffi]

also the PyGeo readme text mentions Numerical python (I think it
means Numeric, but I also have NumPy installed)

afaict, Numerical python is numpy --- if you look at pygeo home page,
the reference to Numerical python is a link to numpy home page

on the contrary, there is no "import numpy" in all the sources of
pygeo, and a couples or so of "import Numeric", so that the situation
is unclear

aiuole/../PyGeo-1.0a1 $ find build| grep py$ | xargs grep -n import'.*'numpy
aiuole/../PyGeo-1.0a1 $ find build| grep py$ | xargs grep -n import'.*'Numeric
build/lib.linux-i686-2.6/pygeo/base/pygeomath.py:1:import Numeric as N
build/lib.linux-i686-2.6/pygeo/base/wiresphere.py:2:import Numeric
aiuole/../PyGeo-1.0a1 $

to complicate matters, it is not possible to install python-numeric
using the apt system on debian unstable

i don't know if it is possible to build numeric against the default
python (2.6) on my system, further i don't know if it is worthwhile
because, at a first sight, it looks like pygeo does not use advanced
features of numeric, and replacing numeric with numpy should be very
easy

numpy supercedes the older Numeric package. However, "numpy" used to be a
colloquial name for Numeric, too.
