Oh, I didn't mean mayavi/examples/test.py but 
tvtk/examples/plugin/test.py.  Can you run the 
tvtk/examples/plugin/test.py (as python test.py) and then select the 
file->new->vtk scene and see if that crashes just like the mayavi2 crash?

OK, that gets us closer but can you please confirm the above?

Thanks!

No, no crash. Seems to work perfectly.

Which release of ETS was this?  2.6.0?  Identifying which release 
actually worked would really help.  Thanks.

This error is really quite weird.  Looks like I'll have to install a 64 
bit ubuntu and actually run it to figure out whats wrong.

BTW, does anyone know if it is possible to install a 64 bit ubuntu on a 
32 bit host Gutsy via virtualbox?

Yes, that is right.

I forgot to say that, explorer3d is working perfectly after resizing the window.
File->New->VTK Scene does not crash.

I don't know about VirtualBox, but you can try to use kvm, see
https://help.ubuntu.com/community/KVM#head-0648a4f455e13fd839c19cb2b2cb7d0d1bf96f4a
there is an example to install a guest Ubuntu inside another one.

EPD Beta Install Issue and Chaco

Hi,

I ran the install on my test system and everything appeared to go fine. 
Now the issues:

1) 2 icons were installed on my desktop (pylab and mayvi). However, I do 
not remember being asked if I wanted these added. It is customary to ask.

2) The file associations do not appear to have been set correctly. I am 
on a windows machine and normally an icon would now be assoc with a .py 
file. Instead there are no icon associations. However, if I right-click 
the file, I can pick which program to use. With a regular python 
install, any python programs have the python icon if listed in explorer.

3) I cannot figure out if chaco2 is properly installed. I would normally 
run one of the programs under chaco2 to see it is working but there does 
not seem to be any examples. If I go to the enthought chaco site all 
there are lots of beautiful examples but only the jpg remains. The links 
to the underlying code have all been moved and are no longer accessible.

4) I did open a file with IDLE once, but now when I right click on a 
file and select open with IDLE it looks like the system tries to do 
something but then returns, so it looks like IDLE died. I can open files 
with SCITE.

Best wishes, Simon

The examples are still missing at the chaco site but I did find the ones 
from the install and one just ran so chaco seems to be installed okay.

Definitely something wrong with the IDLE install. If I right-click on a 
.py file file and select IDLE -- nothing opens!

Would it be possible for you to just remove the installed 2.1 mayavi egg 
and instead install 2.0.2 from here:

http://code.enthought.com/enstaller/eggs/source/enthought.mayavi-2.0.2.tar.gz

The error is really wierd, I'm trying to figure out where the error 
could be.  Doing this would be really helpful.  I will try and setup a 
machine with a 64 bit ubuntu and test but it would be a huge help if you 
could help narrow this down any further.

This is the really weird part, both mayavi2 and the explorer are using 
the same mayavi plugin, it isn't clear what is causing the crash for 
mayavi2.

Re: ANNOUNCE: ETS 2.7.0 released!

I was away last week, so my congratulations come with delay, but I still
wish to express thanks for the work many people on this list have been
doing to deliver this consistent release of many different packages that
fit together for the joy of the user.

I will make tarballs for Debian next week, and we can than update the
Debian and Ubuntu packages. Once this is done, I think I will make debs
for Gutsy, as I believe this is a major release, and it should be easy
for users to install.

> (Some of the) CHANGES FROM 2.6.0 to 2.7.0:

This changelog is really useful for users. Thanks a lot for taking time
to do it. In the long run, is there a way to make it easier for you build
such changelog.

Cheers,

Gaël

Congratulations to all the folks working on this. I do agree EPD plays a

Nice. I am very happy to see that TVTK is used for molecule
visualization. It seems very well suited for this purpose.

Have you considered using Mayavi2 (with the MlabSceneModel, as in this
example
https://svn.enthought.com/enthought/browser/Mayavi/tags/enthought.mayavi_2.1.0/examples/mayavi_traits_ui.py
)
rather than TVTK? I would be interested to know what influences your
choice towards pure TVTK, or Mayavi2 (with eventually some raw TVTK
objects injected into Mayavi2 -- note to self: we need to make this
easier).

Cheers,

Gaël
