I'm running Kubuntu 9.10 and python 2.6.4 on a Thinkpad T41 which sports the dreaded Radeon Mobility 7500 video set. I followed instructions exactly, then began to try example programs. doublependulum worked fine. The next one I tried was stonehenge. I got an error that visual.text could not be found. Then I tried stars, and got an error that newaxis was not defined. Uh oh. Not good. I also tried gyro and gas. The visual.text error came up more than once. Then I noticed that some icons were missing from my system, replaced by question marks. I figured I should at least logout/in, perhaps restart X, perhaps reboot. So I logout via the KDE menu, and the system drops into a character terminal login screen ... unusual ... but I can't log in. Any user name entered resulted in the login prompt returning. No password prompt. I tried other "terminals" (alt-f2, etc) same result. I could get no useful response doing anything I could think of. Out of ideas, I powered down. On restart, a filesystem check started, but ended in failure: filesystem could not be mounted. It did give me a "rescue" terminal session of some sort, and I was able to run fsck. A couple dozen errors were found and repaired. Things like orphaned inodes, broken chains, I don't remember exactly, but I'm sure you get the idea. I don't know if there is any permanent "damage". I wish I could give you more information, but there's not much more to tell. If you think there might be clues left behind, I'll gladly look for them. -gary |

After a bit of googling, the situation seems to be this: matplotlib (http://matplotlib.sourceforge.net) is a Python 2d plotting library which includes a module named pylab. I'm guessing that's what you're looking for. A confusing factor is that at http://www.scipy.org/PyLab there is a discussion that starts out with this: See the following post for further discussion of the difference between the vision for a new PyLab expressed on this page, and the existing pylab package which is part of matplotlib: http://www.nabble.com/pylab-td24910613.html Incidentally, the www.scipy.org/PyLab discussion makes a case for a new pylab to be invoked as "from pylab import *" which would import a bunch of stuff almost anyone doing scientific processing will need (including numpy and scipy), rather like the current situation with Visual. The essayist then says, foreseeing objections, "But there are so many names! Not really. from scipy import * brings in about 20 subpackages (i.e. signal such that you still need to do signal.ifft, but not scipy.signal.ifft) and only 15 new symbols."

PyLab is new to me, but I am familiar with pylab (matplotlib sub). I also strongly suspect that matplotlib is what you want. You don't say what platform you are on, but matplotlib is included in the Ubuntu installation repository. I've found the easiest way to install matplotlib on WinXP is using the stand-alone installer on their website. I think they offer an "easy_install" option, but I've gotten tied up in knots with that from time to time. Now, since Bruce brought it up ... One problem with "from pylab import *" is that matplotlib overwrites some numpy functions, for example linspace(). I don't know why or how that happened, but the two functions behave differently. People probably expect the numpy behavior, but unexpectedly get the matplotlib behavior. Perhaps PyLab does away with this conflict. I don't know.

To use pylab properly in a program you should use the object oriented way: import numpy as np import scipy as sp import matplotlib.pyplot as plt then use them accordingly to your need. The quick use of the console interface a la matlab to try thing can be done using ipython, but should be used only on a try and errors scheme. Some example here: http://www.slideshare.net/mattions/scipy-numpy-and-friends Cheers, Michele On Sat, Nov 28, 2009 at 5:56 PM, Gary Pajer <gar...@gm...> wrote: > PyLab is new to me, but I am familiar with pylab (matplotlib sub).

Hi Gary, the symptoms you've mentioned indicate that something else went (massively) wrong, as I doubt that any "normal" Python process or anything that the Visual library can do would result in such effects. Maybe it's got to do with your graphic card's drivers. Anyway, whatever process *you* start should usually *only* be able to affect user space things. But your descriptions go way beyond what a graphics based application generally would do. I have just checked again here, and all demos I've checked worked. Well, stonehenge.py did not, but that was only due to the fact that the file "flower128.tga" is not present in the samples directory. I don't know, maybe it was removed due to licensing issues or just forgotten. But also all surface textures worked here. It would however be good to track down what your problem is. Maybe not as much for VPython as for your own system's sake. Have a look at /var/log/messages and /var/log/syslog what might have happened and led to the crash. Also check whether other OpenGL based applications show similar effects. Hope these were some hints on tracking down the cause, Guyt -- Guy K.

There are no licensing issues with flower128.tga (I took that picture of cactus flowers myself), and I don't know why it would be missing. Bruce Sherwood Guy K.
