[visionegg] Re: error: OpenGL.ctypes

I downloaded it from:
http://freefr.dl.sourceforge.net/sourceforge/visionegg/visionegg-1.1.2.win32-py2.5.exe
and then double clicked the exe. The installer found the Python25 install 
directory and placed the VisionEgg into  
C:\Python25\Lib\site-packages\VisionEgg.

1) In the shell prompt the results are:

C:\Python25\Lib\site-packages\VisionEgg>python multi_stim.py
python: can't open file 'multi_stim.py': [Errno 2] No such file or directory
 Still there I tried:
C:\Python25\Lib\site-packages\VisionEgg>python gratings.py
Just nothing happened.

2) Via Python console I got:
File "<stdin>", line 1, in <module>

Name error: name 'os' is not defined

Really no idea what might be wrong.

VE is compatible with win32. If you're getting an error on double click
it means something is going wrong. You can try one of two things:

1) keep that error around longer. Open a shell console: Start->Run->type
"cmd.exe". Then "cd
C:\Where\the\VE\demos\are". Then "python
multi_stim.py".

2) Run the demos from within the Python console: type
"os.chdir(r'C:\path\to\VE\demos')" then type
"execfile('multi_stim.py')"
when in the VE demos directory and report back the error you see.

The problem you're encountering is that _vegl is an internal module to
the VisionEgg and you shouldn't import it directly.

How did you install the Vision Egg?
