Hi All, I think we have tracked down the problem with Vpython seg faulting on 64 bit Ubuntu with NVIDIA drivers. It appears that some packages install a minor version upgrade of some glx libraries that cause the breakage. The following command restores a working VPython for us: sudo apt-get install libgl1-mesa-glx=8.0.2-0ubuntu3 libglapi-mesa=8.0.2-0ubuntu3 This reverts from the 8.0.3 version of these packages down to the 8.0.2 that was the original install and that the stock NVIDIA drivers are apparently built against. So we now have Vpython working on 64-bit Ubuntu using both the stock NVIDIA drivers and python-visual that come with Ubuntu. --John John Zelle, PhD Professor of Computer Science Wartburg College ________________________________________ From: Bruce Sherwood [Bru...@nc...] Sent: Monday, September 03, 2012 10:45 AM To: vpusers Subject: Re: [Visualpython-users] seg faulting I guess this proves that my experience with the Boost libraries is irrelevant.

Hi Bruce, I don't think your experience is irrelevant. I also suspect that the Boost updates play a part in this (Of course, I ALWAYS suspect Boost).. It may be that there are multiple breakage points in the Ubuntu packaging. Unfortunately, there does not appear to be a simple way to recursively "reinstall all dependencies" of the python-visual package.It appears that some library is getting tweaked, but the python-visual package is perfectly happy with the update until one actually tries to run VPython. Anyway, I'll let you know when we track it down. --John John Zelle, PhD Professor of Computer Science Wartburg College ________________________________________ From: Bruce Sherwood [Bru...@nc...] Sent: Monday, September 03, 2012 10:45 AM To: vpusers Subject: Re: [Visualpython-users] seg faulting I guess this proves that my experience with the Boost libraries is irrelevant.

Hi All, Let me second what Guy is saying. I am attempting to run VPython using the stock Ubuntu package (python-visual Ubuntu 12.04, 64 bit), not building it myself. It works out of the box with a clean install and update of all installed packages. However, it appears that some other package that I install later on breaks VPython. It also appears that the issue is somehow tied to NVIDIA drivers, since I don't have this problem on machines with Intel graphics.

I don't quite understand all the comments about NVIDIA. The fundamental problem on my Ubuntu 12.04 is that (apparently) an automatic update to the Boost libraries yanked away the version that I had used when building VPython on my machine. It was only after rebuilding with the newer Boost libraries that I got what was actually a rather clear message about a problem with NVIDIA software. Bruce Sherwood |

And they're right. Well, that's true. However, some of these problems can be circumvented by stating certain constraints in the meta-data of packages. E. g. that things are incompatible with certain versions, etc. Therefore problems can be resolved when installing, rather than providing an unexpected trip wire to the user. So things can be taken care of at the level of packaging, rather than tampering with a black box binary package that is shipped for convenience installable through the Debian/Ubuntu package management. At least let the package maintainer know! If nobody knows, people with better overview over the environment won't be able to help! Guy -- Guy K.

And they're right. Nvidia won't release hardware details in enough detail for the Linux community to be able to write a decent driver. The charitable explanation is that this would give away too much info about their hardware to competitors; the cynical explanation is that it would reveal patent violations to those competitors. In the eyes of the FSF, they're just Proprietary and therefore Evil. So just as on MS Windows, if you want high performance 3D graphics on Linux with GeForce or Quadro you download your driver directly from nvidia. (Same goes for ATI.) But unlike Microsoft, the Linux kernel developers don't care about breaking binary only drivers in new releases. Their attitude is "we'll take responsibility for updating all your drivers when the kernel changes IFF you give us the source code." My impression is that most buyers of NVIDIA 3D cards for Linux are doing special effects, CAD, flight simulation, or similar "high end" work. (A lot were bought as replacement for SGI workstations.) They're in companies big enough to have IT support staff to deal with the update hassles. Unlike MS Windows, there's no significant gaming market of individual users who need seamless hands-off updates. Unless that changes - which to be honest I can't see happening - nvidia will keep their driver closed source. -- Hugh Fisher CECS, ANU |

I have little experience with Linux, so I don't feel competent to make a report. Nor do I know for sure that it was an automatic update of the Boost libraries that was at fault. It would be interesting to know whether someone else who has had problems was able to fix things in the same way that worked for me. Bruce Sherwood On Sun, Sep 2, 2012 at 4:21 PM, Guy K.

OK, did anybody actually make the effort and report those bugs/fixes upstream to the Ubuntu team [1] or even better the Debian team [2]? Without that, I doubt that there'll ever be a "stable" situation where these things can be taken care of by the distributors, which won't help a wide spread use or the reputation of VPython. Particularly a report on how to fix it would likely make it quickly into the releases.

Fixed. When I tried to run, I was told that a libboost library was missing. I made sure that there was a complete set of development libraries for libboost python, signals, and thread, rebuilt. When I ran this rebuilt VPython, I was told that there was a mismatch between components of the NVIDIA driver environment. I looked up that error message on the web and followed instructions to purge NVIDIA files and reinstall, then reboot. Now VPython works. All of this presumably is due to the updates that Ubuntu continually wants to do, which have the effect of causing various kinds of failures. It seems like you still have to be very expert with computers to be able to use Ubuntu, and you need to know how to search the internet to find out what arcane procedure is needed to be able to continue using the system.

I find that several different VPythons on my seldom-used 64-bit Ubuntu machine have stopped working (for Python 2.7, 3.1, 3.2). There is a hint that maybe an automated update to libboost killed them.

Hi, I am talso rying to run Vpython on a 64-bit Ubuntu 12.04 and having this problem. I don't think it's the new NVIDIA driver per se causing the issue. What I have discovered is that python-visual works fine on a clean install (including updates). However, as I install other packages, the visual module eventually breaks. This happens during a lab install that includes lots of additional packages that I install en masse. I started installing packages one-by-one and testing after each install. I got about 1/2 way through and had installed everything that I thought could possibly be related; vpython still worked. Then I got impatient and installed all the rest. Naturally, it broke again. It seems to me some package is installing a tweaked version of a library (perhaps something in libboost???) that kills vpython. I will have a lab assistant again starting next week, and I am going to have him go through package by package to see if we can find what's breaking the python-visual module. --John John Zelle, PhD Professor of Computer Science Wartburg College ________________________________ From: Andrew McCormick [agm...@gm...] Sent: Friday, August 31, 2012 6:19 AM To: vis...@li...

First, thanks for the help. I was kind of excited to see that their was a namespace conflict, ultimately thinking it would be an easy fix. So, I renamed the file to something more obscure and and tried to run through PyCharm again (I actually created a new file, copied and pasted, then deleted the vis.py- rather than just renaming the file). At least I'm getting somewhere, as the error is different, lol. This is the error that I got: C:\Python32\python.exe C:/Users/airspoon/PycharmProjects/goo/vp002.pyImportError: numpy.core.multiarray failed to importTraceback (most recent call last): File "C:/Users/airspoon/PycharmProjects/goo/vp002.py", line 1, in <module> from visual import * File "C:\Python32\lib\site-packages\visual\__init__.py", line 1, in <module> from .visual_all import * File "C:\Python32\lib\site-packages\visual\visual_all.py", line 1, in <module> from vis import version File "C:\Python32\lib\site-packages\vis\__init__.py", line 3, in <module> from .cvisual import (vector, dot, mag, mag2, norm, cross, rotate,SystemError: initialization of cvisual raised unreported exception And for what it's worth, this is the code that was copied and pasted from the vPython website: from visual import * floor = box (pos=(0,0,0), length=4, height=0.5, width=4, color=color.blue)ball = sphere (pos=(0,4,0), radius=1, color=color.red)ball.velocity = vector(0,-1,0)dt = 0.01 while 1: rate (100) ball.pos = ball.pos + ball.velocity*dt if ball.y < ball.radius: ball.velocity.y = abs(ball.velocity.y) else: ball.velocity.y = ball.velocity.y - 9.8*dt All other 3rd party libraries that I've used with Python seem to be working correctly, so I doubt the issue is with my Python distro.

Yeah sounds like some bad luck in terms of namespace collisions. They're still quite possible. I'm deep into PyCharm / virtualenv issues (or maybe it's just that I'm not deep enough), but none seem to involve VPython, other than the fact it's sad there's no pip install route (or at least I couldn't find it).
