[Visualpython-users] Problems in Running Some Vpython Scripts

[Lorenzo I. <lor...@gm...>]

Dear All,
I am fairly new to Vpython (and not a terribly experienced Python
programmer in general).
I am running Debian testing on my box and I installed Vpython from
Debian's repositories.
Now, I first tried running some online scripts. Some of them run fine,
but with other ones I get obscure (to me) error messages.

For instance when I try running the script at:

http://physics.syr.edu/courses/PHY307/LABS/lab7.percolation.py

This is what I get.

$ python lab10_BKearthquake.py
Traceback (most recent call last):
  File "lab10_BKearthquake.py", line 17, in ?
    background=color.white, foreground=color.blue)
  File "/usr/lib/python2.4/site-packages/visual/graph.py", line 192, in __init__
    currentdisplay.select()
RuntimeError: boost::bad_weak_ptr

Anybody has experienced the same problem?
Many thanks

Lorenzo
