[Visualpython-users] Efficiency

[James R. <u32...@an...>]

Hi,

I'm using vpython in computational simulation.  A little concerned about 
the efficiency, I ran the following tests:

from visual import *
import profile
import datetime

def dostuff(n):
    for i in range(n):
        for i in range(n):
            pass

timea = datetime.datetime.today()
profile.run("dostuff(1500)")
timeb = datetime.datetime.today()
t = timeb - timea
print "Actual running time: %i.%i seconds" % (t.seconds, t.microseconds)

ball = sphere(pos=(0,0,0), radius=1)

timea = datetime.datetime.today()
profile.run("dostuff(1500)")
timeb = datetime.datetime.today()
t = timeb - timea
print "Actual running time: %i.%i seconds" % (t.seconds, t.microseconds)


And I got this output:
Visual-2003-10-05
         3 function calls in 1.250 CPU seconds
   Ordered by: standard name
   ncalls  tottime  percall  cumtime  percall filename:lineno(function)

Actual running time: 10.847798 seconds

This in my view is pretty poor efficiency, considering that visual 
python is doing nothing but displaying a static ball on the second call 
to dostuff().  Is there anyway to tell visual python to lay off and do 
nothing for a while?  So... in the context of my work, when I call the 
functions that do all the hard work, i would tell visual python to do 
nothing, and then when the functions return, i'd tell visual python to 
start doing stuff again.  BTW, what is it doing that slows everything 
down so much?

[Visualpython-users] VPython on OS X 10.3 Panther?

[John N. <joh...@co...>]

I am in a physics course that has chosen VPython to do some of the computer
modeling.  Unfortunately, my machine runs OS X 10.3, which doesn't seem to
be supported by VPython (yet?).

The main problem as far as I can tell is that Panther already comes with a
near-complete install of Python 2.3, MacPython installs the Package Manager
and IDLE (Numeric is an option in the Package Manager).  I don't want to
install Python2.2 on top of all that, I imagine it would break lots of
things.  So I guess I would need to install the fink packages listed, and
then somehow link Visual to the built-in Python2.3 included with Panther.

Thanks for any and all help with this.

I want to keep bash, primarily because I want to learn to use it

I didn't see anything specifically for bash, but I could have surely 
overlooked it. I'll check again.

Any idea why the BROWSER variable doesn't seem to be working? It worked 
fine under 10.2.x and Fink's Python 2.2. I was using the exact same 
VPython tarball too.

Hi Joe;

Glad to hear that things are working.  Some Unix and fink-related
notes:

1)  To change your shell (back) to tcsh, type:

			   chsh (username)

    and then enter /bin/tcsh at the prompt.

2)  To put vpython in your path, you will need to have /sw/bin in your
    path, which means adding the (appropriate) line to your .cshrc or
    other shell-appropriate startup file.  This procedure is
    documented in the fink install instructions.

3)  X11 and xterm get environmental variables from the shell (ie X is
    a windowing system, not a shell).  

4)  I've amended the posted build instructions to include the
    directions for the bash shell.

[Visualpython-users] VPython working on Mac OS 10.3.2

[Joe H. <hea...@ct...>]

Good evening.

Using Kevin Chu's instructions at

<http://www.uvm.edu/~kchu/?Page=VPython/ 
BuildingVPython.html&SM=miscsubmenu.html>

I too have built VPython under Mac OS 10.3.2. I first installed the  
latest Fink and FinkCommander (a graphical front end to the Fink  
system) and all went well until I tried to build gtk+. There was a  
failure somewhere near the end that prevented the built packages from  
being installed. I suspect I goofed something up because I set  
FinkCommander to use the unstable tree so I wouldn't have to copy over  
the python23 info and patch files ad Chu describes. This didn't work,  
so I wiped out Fink and FinkCommander and reinstalled Fink. This time,  
I copied over the info and patch files as directed. However, I issued  
"fink selfupdate" rather than "fink selfupdate-cvs" and all worked fine.

Apple has made bash the default shell now and this caused me to  
stumble. Environment variables must be set as

export CPPFLAGS="-I/sw/include -I/sw/include/gtkgl" (note the quotes  
needed for multiple arguments)
export BROWSER=open

I realize the reference to /gtkgl is not needed. I verified these env  
variables had been correctly set with

echo $CPPFLAGS
echo $BROWSER

I'm curious as to why the LDFLAGS env variable didn't need to be set.  
After a successful build and install using the  
visual-2.1.9-20031005.tar.gz tarball, I fired up X11 and the vpython  
script and got the new IDLE environment and was able to run VPython  
programs. The only issues I see are:

  1) Hitting F1 fails to bring up the web browser with help docs. From  
xterm, I saw that the BROWSER env variable didn't exist so I set it  
manually (X11 apparently uses bash too), and still it didn't work. I  
tried setting this variable in ~/.profile but still no luck, although  
this does set the variable in Apple's Terminal program.

2) X11 doesn't know about /sw in the PATH, so I have to type  
"/sw/bin/vpython &" to start VPython.

 From where do xterm and X11 get information about environment variables  
  under 10.3?

Otherwise, I now have VPython running under Panther.

Cheers,
Joe Heafner -- Astronomy/Physics Instructor

[Visualpython-users] Stand-alone; Cygwin

[Bruce S. <bas...@un...>]

Thanks to efforts of David Andersen, there are two new features at 
http://vpython.org. In the FAQ are his instructions on how to create a 
stand-alone VPython program. In the developers' section are instructions 
and files for compiling Visual on Windows using the freeware Cygwin 
Unix-like environment rather than Microsoft Visual Studio.

The python IDE that comes up is X-ish of course, and so keybindings for  
commands like Open File  use control -O  rather than the OS X  
command-O.  So I'm trying to get quickeys to make the substitutions for  
me.

I've also found that I can run vpython scripts from OS X environments  
such as that created by voodoopad if I programmatically set the python  
interpreter to /swbin/python,  set the  pypath, and set the display  
variable for the X server.  Thus, this works is X11 is running  
concurrently.

Which has me wondering whether the OS X can be tweaked to provide an OS  
X IDE  But I haven't tried that yet.

Anyway this is a much better place to be.  Thanks to everyone for their  
help.

Hi Jonathan;

The gtkglarea.h include is a old habit to deal with a bad 
VPython-building experience earlier.  You're absolutely right that it 
shouldn't be in there.

Thank you for your help and feedback, Mr. Chu.  The only thing about
your instructions that jumped out at me is that I don't think you should
need to add -I/sw/include/gtkgl to CPPFLAGS.  gtkglarea.h is referenced
as gtkgl/gtkglarea.h in the source code.

Also, support for the 'distclean' target in the cvisual subdirectory has
been added to CVS.  Thanks for pointing out that deficiency.

No.  glxgears doesn't use either pango or glib2, it directly uses the
X11 protocol.  Visual doesn't use pango or glib2 either, since it uses
gtk+ 1.x.

FYI, Pango is the internationalized text engine for Gtk+ version 2 (and
later).

-Jonathan Brandmeyer

Re: [Visualpython-users] Instructions for building VPython on MacOSX 10.3 and Python 2.3

[Kelvin C. <kel...@uv...>]

I'm no expert, but my machine doesn't have pango installed at all.   
Therefore, is it there because you've used it for another package?  A  
quick search through the 10.3/stable directory shows that the packages  
below depend upon pango.  I have gtk+ installed, but not gtk+2.

habanero[~]% find /sw -name \*.info -print | grep -v unstable | grep  
10.3 | xargs grep pango | grep -i depends | cut -d ":" -f 1

/sw/fink/10.3/stable/main/finkinfo/editors/bluefish.info
/sw/fink/10.3/stable/main/finkinfo/games/dopewars.info
/sw/fink/10.3/stable/main/finkinfo/games/dopewars.info
/sw/fink/10.3/stable/main/finkinfo/gnome/gtk+2-2.0.6-4.info

/sw/fink/10.3/stable/main/finkinfo/net/gaim.info
/sw/fink/10.3/stable/main/finkinfo/net/pan.info

None of them appear to be required for vpython.

Good news and bad news

#1:  First, Kevin's instructions were superbly clear and I was able to  
follow them without only one hiccup on a non-clean 10.3 system recently

Second, they do seem to have built me a fresh python.  When I type  
visual, I now get

This is apparently unrelated to Python (but I'd still like help!!),  
since I can't run glgears either:

any suggestions??  Might the pango / glib2 hiccup be the issue?

[Visualpython-users] Instructions for building VPython on MacOSX 10.3 and Python 2.3

[Kelvin C. <kel...@uv...>]

Below is a link on how to build VPython on MacOSX 10.3 using Python 2.3.

http://www.uvm.edu/~kchu/?Page=VPython/ 
BuildingVPython.html&SM=miscsubmenu.html

I built VPython yesterday on a fresh (10.3 eMac) starting completely  
from scratch.  Please let me know how this works for you so that we can  
refine this process and make it as painless as possible.

Re: [Visualpython-users] MacOSX 10.3, Python 2.3 and Visual.

[Jon S. <js...@so...>]

interesting, thanks

for the record, I can get that far, but if I try do something...

from visual import *
sphere()
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkWidget'
OpenGL initialization failed.
   Unable to create OpenGL display widget
<Primitive object at 0x492164>

so now I"m trying to figure out OpenGL 8-/

Well, that's *very* interesting.  In my testing I received an error
related to an extension module API mismatch.

I should add that since I haven't actually gotten my hands on MacOS 10.3 
that all of my testing with Python 2.3 to date has been on Windows 
and Linux.

Thanks for the information,

Here's the setup.

1.  MacOSX 10.3 was installed as an upgrade to MacOSX 10.2

2.  Python 2.3 was installed via fink.  To do this (and to install 
numeric and a bunch of other Python2.3 things) you will have to locate 
the packages and move them from the unstable to the corresponding 
"stable" directory.  I have not noticed any actual instability in these

3.  VPython was installed using the binary from vpython.org.  The 
'vpython' that lives in /sw/bin calls the Python 2.2, but you can of 
course change this.

If people need it, I can find a fresh 10.3 install machine and see what 
needs to be done in order to get this running.

Re: [Visualpython-users] installing vpython on OS X 10.3

[Jon S. <js...@so...>]

that's easy.  One big package would be a bargain!  for 2.3 or 2.2.

Did you see Gary Pajer's comment re 2.3?

Of course I can't figure out how to get the fink version of 2.3.  I 
think it has to do with" unstable..."

The configuration issues in this universe (not vpython; it's context 
are really unbelievable).

If you're free to help me get either a 2.2 or a 2.3 installation 
working right now, I'd be very grateful.  I can be iChatted at 
"jonschullaim"

I had a great project vpython project in mind for the weekend.  But 
here I am working on installs (he said bitterly).

Well, I'm afraid that VPython hasn't yet run on 10.3 to my knowledge,
and I know that the binary package on vpython.org is incompatible with
10.3.  Chances are that I would need to do some experimentation to make
it work.  I've heard that 10.3's stock Python doesn't include tkinter
either, so that is going to be another interesting thing to work out :)

We don't have a 10.3 machine on campus that I have access to yet, and
Dr. Sherwood is on vacation right now.  If someone would like to
volunteer a non-administrative user account with SSH access I could do
some work on this as soon as the 23rd.

On another note, if it is possible for us to supply a package that
doesn't depend on fink but was larger (probably several megabytes), is
that something that people are interested in?  Or would you rather get a
smaller package that uses fink for some of its dependencies (eg, gtk+)?

Re: [Visualpython-users] installing vpython on OS X 10.3

[Gary P. <pa...@in...>]

 Not sure, but I can add two comments.

 First:  vpython works with the fink version of python 2.3.  Not the one
that
 ships with OSX, I believe.

 I tripped on the Apple SDK.  It comes with several packages.  You want to
 make sure that you install DevTools.pkg  and  DevSDK.pkg.   Installing only
 Developer.pkg didn't work for me.

 I think I'd try installing python2.3.  You don't have to uninstall 2.2
 (ymmv) but you better make sure that /sw/bin/python calls the right
version.
 (just type "python" at the bash prompt and see what comes up.)  Of course
 you can gronk 2.2 if you want.

 oh ... my installation is on 10.2 so ....

[Visualpython-users] installing vpython on OS X 10.3

[Jon S. <js...@so...>]

Assuming that I need python 2.2.3 (not OS X 10.3's native python 2.3), 
I've been able to step through all  instructions at 
http://vpython.org/OSX_download.html right up to typing vpython.

At that point I get the error,  "No module named _socket"

[Visualpython-users] executable

[David A. <DAn...@co...>]

Using py2exe-0.5.0a5 (the latest version from sourceforge) I was able to
build and run "stars.exe".

I used the following "setup.py" file and ran "python setup.py py2exe" - t=
he
build process gave a warning about a missing "dotblas"  (part of the
Numeric package I believe), but the resulting executeable ran with no
problem.   I also built "stonehenge.exe" - it also worked.

[Visualpython-users] configure problems

[<eh...@uc...>]

Thanks if you can help me figure this out.
I've got both python2.2 and python2.3 (RH9), but want to configure visual with 2.3.  Numeric is installed and works with 2.3.  I've tried using $PYTHON=, $PYTHON_VERSION=, and --prefix= but always get the following errors(see additional note *** below): 

checking whether to enable maintainer-specific portions of Makefiles... no
checking for a Python interpreter with version >= 2.2... python
checking for python... /usr/bin/python

***(2.3 is here: /usr/bin/python2.3, but configure always looks for this pyhon which is 2.2)***

checking for python version... /usr/lib/python2.3/os.py:282: Warning: 'yield' will become a reserved keyword in
the future
'import site' failed; use -v for traceback
2.2
checking for python platform... /usr/lib/python2.3/os.py:282: Warning: 'yield' will become a reserved keyword in the future
'import site' failed; use -v for traceback
linux2
checking for  script directory... ${prefix}/lib/python2.2/site-packages
checking for  extension module directory... ${exec_prefix}/lib/python2.2/site-packages
checking for array in python module Numeric... no
configure: error: Numeric Python is required.  See numpy.sourceforge.net or your local OS distribution.
