Vpython

[Captain_Falafel]

Does anyone know how to get vpython working under Ubuntu 9.10?
I've got IDLE (using python-2.6) installed as my python shell window, but I can't seem to get visual python working.
I know that there's a package in the repositories - visual python, which I've installed, but I can't seem to run it somehow. I've gone to their site with no luck on installation.

Does anyone know anything that could help? Thanks in advance

I'll bump this thread as well.

Just installed vpython on 9.10.

When I try to run the simple code

from visual import *
sphere()

using IDLE, nothing happens. When I try to run the code using the command

python filename.py

I get the error

Segmentation Fault

With no other information.

OK, the issue seems to be fixed by including the software source available here.

However, you can't interact with the visualization window with the mouse. I'll try to sort this out tomorrow, but I think the initial issue might be taken care of.

I've added the software sources, but which packages do I install?
My problem usually occurs when I want to run a python script like this one for testing:

from visual import *
sphere()

All of a sudden, both my script manager and the python shell crash

I also updated the sources. Removed and re-installed python-visual. Nothing new.

What's your problem.. is the python shell and vpython crashing when you try to run a test script?

[Gawains Green Knight]

I saved

from visual import *
sphere()

to a file named test.py and then ran

python test.py

to only receive a segmentation fault.

Never used python before so I may be doing something stupid....

Anyone had any luck with this yet?

Edit: Above fix seems to have worked on my xubuntu 9.04 (I'll have to see why it didn't work on my 10.04 at home), but now I'm seeing...

Edit:Edit:

sudo apt-get install libgtkglextmm-x11-1.2-dev

seems to fix it, but the window is a little messed up (no boundary or anything). But it works! Thanks!

Re: the fix above.

For me, adding the source lists I mentioned in my previous post, then running

sudo apt-get update

and

sudo apt-get upgrade

Allowed me to run a vpython script and have it produce the desired result.

I am unable to rotate or manipulate the figure produced with the mouse cursor, so perhaps an additional package that allows 3-d visualization (e.g. OpenGL) needs to be installed?

I haven't really looked into the issue since my last post, so maybe I will do that in the next couple days.
