[Visualpython-users] Crash on py2exe

[Davidmh <dav...@gm...>]

Hello.

I have compiled successfully several programs to Windows binaries usin
py2exe, but when I try to execute a working program depending on
VPython, I get the following error:

Traceback (most recent call last):
  File "mirage.py", line 2, in <module>
  File "visual\__init__.pyc", line 66, in <module>
  File "visual\ui.pyc", line 3, in <module>
  File "visual\materials.pyc", line 151, in <module>
  File "visual\materials.pyc", line 129, in loadTGA
IOError: [Errno 2] No such file or directory:
'C:\\pyex\\dist\\library.zip\\visual/turbulence3.tga'

I use Python 2.5, and as I have seen, there have been more people with
the same problem. The only solution reported I have found is simply
deleting the definition on the module source code. Although inelegant,
it could work, as long I am not using any materials in my program; but
I don't like editing that kind of source.

I think the option "excludes" could be used, but after several tries I
haven't been successful.

Any ideas?


Thank you;

David Menéndez.

I always include all the tga files explicitly:
  if Include_VPython :
    Data_Files.append ( ( r'visual', glob.glob (
      r'P:\Python\Lib\site-packages\visual\*.tga' )))

Where? In the setup for py2exe or in the original source code?

Thanks for your help.

Re: [Visualpython-users] Crash on py2exe

[Davidmh <dav...@gm...>]

Hello. I have finally fixed the problem in a somewhat silly way:

try: from visual import *
except:pass

I figure the crash is before the important parts of visual are
imported, so it can go ahead. It won't work on programs that depend on
materials.


Regards,

David.

Can you please at least try to capture a *specific* exception? Harvesting off 
*all* exceptions is usually a *very* bad design decision, and much frowned 
upon.

If there's a problem, take a note of the exception, and then use precisely 
that one in the try/except block. I know there are quite some programming 
newbies also here on the list, and I do not like to leave these sloppy code 
samples around here to be adopted (and worsened in the course).

Thanks,

Guy

Hello.

In some new scritps, when I compile them with py2exe, I get:

Traceback (most recent call last):
 File "show_scene.py", line 5, in <module>
NameError: name 'display' is not defined


Of course, the original .py script, before Py2exe works great without
raising errors. The five first lines, until the crash are:

1· try: from visual import *
2· except IOError: pass
3·
4·
5· scene=display()


Trying to figure how to solve it, I remembered some VPython scripts I
compiled some months ago, that were functional; but when I try to run
them, I get similar errors. In this same computer, they ran perfectly
time ago. I don't remember doing any big modification in the OS
(appart from the security updates), nor touching the Python
installation (although this should work anyway).

More testing brings more weird results. Testing both old and new
scripts in another similar computer, the old one works great (as it
should), but the new one still says the same error.


Anyone has any idea on why is it happening and how to solve? Thank you
very much.

David.


P.D.: if anyone needs the complete scritps, just ask for them; I don't
have any problem in publishing them.
