Yes, these packages work together. Mayavi2.2 may not require the latest
python-enthought-traits and python-enthought-traits-ui, some of the bug
fixes of python-enthought-traits and python-enthought-traits-ui are
actually driven to fix problems in mayavi2.

2008-06-29 Thread Gaël Varoquaux
Indeed. I can confirm this. AFAIK this is a compiz bug, and not a
tvtk/mayavi2 bug. The root of the problem lies in the fact that tvtk and
mayavi reparent a GL rendering window.

It is. This code that is in python-enthought-traits-ui should really be
moved to mayavi2. The whole ethnought.pyface.tvtk should be moved to
enthought.tvtk.pyface (whcch lives in the mayavi2 Debian package). This
is historical, because at some point we where considering these projects
as non independant. These 2 projects are a split of the same SVN for
modularity: the python-matplotlib project (to which we are not directly
related) uses the python-enthought-traits project. The
python-enthought-traits-ui project is the ui part of the
python-enthought-traits project. It is not currently used by another
Debian package, but it is used in other projects, who do not use the 3D
plotting code in mayavi2. Thus they do not want the dependency on vtk,
which is a heavy dependency. We will probably need to split the Debian
packages a bit more, as time goes on, as this code is very modular, and
there are usecases for its modularity.

As the python-vtk project as declared wxVTKRenderWindow obsolete and
unmainained, we have declared the SimpleScene obsolete and have removed
in from the api. It is still in the codebase, and can be imported
directly from its source file, but this will cause a traceback when used
with wxpython2.8.

When we did this, we surveyed our users, and the SimpleScene was not used
anywhere. People use the Scene, and so did we in mayavi.

So as a conclusion, this is an API breakage, but to react to a wxPython
API breakage, and the packages python-enthought-traits,
python-enthought-traits-ui and mayavi2 are stronly linked.

I hope the clarifies a bit things.

Gaël

OK, it took me pretty much one hour to figure out that the change that
fixed this problem is the following one liner: in package
python-enthought-traits-ui, in file enthought/pyface/tvtk/api.py, remove
the second line, ie "from simple_scene import SimpleScene".

One my box (ubuntu hardy) this fixes the problem. Can somebody confirm it
does for him.

Hopefully this means we can call this bug fixed, right?

What's SRU?

I can make a special patch, it is just going to take me precious time,
that I would much rather spend elsewhere, especially since the release
I'd be patching for is quite old (around Christams, I think) and has
quite a few other bugs that where fixed.

OK, that's an interesting piece of information.
It seems to be in the python-vtk, as the following line fails:

from vtk.wx.wxVTKRenderWindow import wxVTKRenderWindow

Actually, know that you point it out, this is a know issue. The
wxVTKRenderWindow is depreciated, and does not work with wxpython2.8. The
solution is to use a different RenderWindow, and we switched to that in
newer versions of Mayavi2. There will soon be a new release of mayavi,
and we are planning to push it into hardy-backports. In the mean time you
can get some package that (I believe) do not display this bug on my PPA
(they are a slightly newer version of Mayavi2).

We have a few problems with VTK 5.3 that we want to fix with Mayavi2? and
after that we do a new release. Hopefully in a week. Give another week
for the Debian packages to follow, and the MOTUs to sync with Debian, and
backport, and you should have a nice and shiny new version of Mayavi2,
with this fix, and other ones.

Hi,

The traceback you are getting is actually not where the exception was
generated, as lazy loading hide the real error. Mayavi does run on some
boxes, and I can't reproduce your problems, so we need to find out what
is wrong. Can you please remove the file
~/.enthought/enthought.mayavi/ets.log , launch mayavi2 once, to get that
error message, and then send us the above log file.

Cheers,

Can you give us more information. In particular how you installed mayavi
(if you indeed did install it using the package, could you check the
version of your package). Can you also give us the traceback in FBI
(there is a tab called "traceback", you can copy and paste it in here).

Finally, can you please test mayavi without the interface. To do this,
you can run "ipython -wthread" (using the package "ipython"), and enter:

from enthought.mayavi import mlab
mlab.test_contour3d()

You should see a window poping up with a visualisation. If you don't,
could you please post the traceback here.

Wow, that's ugly.

Let's try to diagnose this.

Can you try to access Mayavi functionnality throught ipython, for
instance, run "ipython -wthread", and run the following commands:

from enthought.mayavi import mlab
mlab.test_contour3d()

You should see a window poping up, with 3 isosurfaces. You should be able
to rotate the view with the mouse. Going to fullscreen yields a crash
with the version you have.

If this doesn't work, we'll try an even simpler test, can you run the
following script (with the standard python):


from enthought.traits.api import HasTraits, Str

class A(HasTraits):
a = Str()

A().configure_traits()


You should have a very simple dialog that pops up, with a text box to
edit a string.

Please give me the results of these tests with any traceback.

I can fully understand that. IMHO the 2.1 release is much nicer than the
2.0, but I know very well why you choose not to force a sync, and I
respect the decision a lot, as I know that it is more important to be
stable and predictible rather than leeding edge.

I don't run hardy :->. I could set up a VM, but each time I have done
that, I have lost a full evening (if you have VMs already set up that I
can use, I would be happy trying them out).

Our tracking of changes is pretty poor I am afraid. I can't give you a
list of all the small changes done. Changes from 2.1.0 to 2.1.1 where
just a few bugfixes in python-enthought-traits and
python-enthought-traits-ui, but as mayavi2 depends on these, we had to
make a new release.

The changes from mayavi2.0.2a1 to mayavi2.1.0, and those to the two other
packages it is closely tied to (that is changes from ETS release 2.6.0 to
2.7.0), are exposed in 
https://mail.enthought.com/pipermail/enthought-dev/2008-February/012908.html

  * [Envisage] Fixed numerous examples so that they run again.
  * [Envisage] Changed icons to better match downstream licensing
  * policies.
  * [ETSConfig] Minor change to allow the Envisage refresh code plugin 
to work without raising a traceback.
  * [Kiva] Fixed examples so that they run again.
  * [Mayavi] Significant documentation improvements.
  * [Mayavi] Increased number and reliability of examples.
  * [Mayavi] Enabled Mayavi to run outside of an Envisage app.  It can 
now display also in a Traits UI.
  * [Mayavi] Moved enthought.mayavi.tools.mlab to enthought.mayavi.mlab.
  * [Mayavi] Exposed modules and filters via mlab.
  * [Mayavi] Added full support for tensor visualization.
  * [Mayavi] First cut for new options framework.
  * [Mayavi] Using new API for adding widgets to a scene.
  * [Mayavi] Add the possibility to specify to which scene a source 
should be added.
  * [Mayavi] Remove wxversioncheck that caused problems in too many
  * cases.
  * [Mayavi] Reimplemented VTKFileReader to be a subclass of 
VTKXMLFileReader thus making codebase smaller and more consistent but 
also allowing reading of OpenFOAM data.
  * [Mayavi] Added option to enable/disable the auto updating of ranges 
used in contours.
  * [Mayavi] Numerous bug fixes and other minor enhancements.
  * [PyFace] Fixed full screen TVTK scenes issues.  Full screen should 
also work with VTK 5.0.3.
  * [PyFace] Added new TVTK SceneModel and SceneEditor classes that let 
one embed a scene and manipulate it from within a Traits UI.
  * [PyFace] Added a configure scene button to the TVTK scene widget so 
that users can configure the background and foreground colors, etc.
  * [PyFace] Added a new TVTK SceneEditor that supports actors and 3D 
widgets.
  * [PyFace] Removed SimpleScene from the standard api.py module since 
it is not commonly used and generates unnecessary warnings.
  * [PyFace] Refactored the TVTK actor_editor and actor_model into 
separate modules to facilitate easier porting to PyFace 3.
  * [PyFace] Fixed splitwidget to work with wxPython 2.8.
  * [Traits] Added an auto_close_message function and corresponding UI 
dialog.
  * [TVTK] Added support for local VTK classes that a user may have
  * built.
  * [TVTK] First cut at a meaningful README.
  * [TVTK] Fixed bug with DataExtent being treated as a state method.
  * [TVTK] Fixed a problem with unnecessary overloading of certain 
traits and methods.
  * [TVTK] Updated dependencies so that TVTK works with in-development 
versions of Traits 3 and PyFace 3.

You are not interested in kiva-releated changes, as kiva is not part of
these three Debian packages.

These changes are mostly additions and bug fixes. The most important
change is:

  * [Mayavi] Moved enthought.mayavi.tools.mlab to enthought.mayavi.mlab.

This will become a backward-incompatible change in the feature
release. For now it only raises a deprecation warning.

I suspect this changelog is quite incomprehensible if you don't know the
details of mayavi and traits. It boils down to:

* A lot of small bugfixes.
* Huge documentation improvements
* Significant bux fix for fullscreen (this was causing a segfault
  under Debian)
* Addition of new APIs that will in the long run deprecate some old
  ones, but know are just exposed to the user to get feedback (the
  mlab.pipeline submodule, the TVTK SceneModel and the
  MlabSceneModel).
* Removing some code that was causing crashes because it was using
  deprecated code in VTK. This is not a loss to users, because under
  Linux, it was simply not working.

I am having difficulties making this more clear without going into
technical details. If you have questions about a specific item, don't
hesitate to ask.

So mayavi2 still does not install under hardy. Hum, this is really bad.

AFAIK we do not hardcode any paths in Mayavi2. We heavily really on
setuptools (for the best or the worst :->).

Would simply syncing the debian package be an option? The upstream code
itself was consolidated quite a lot, and few features where added, so I
would hope that no new bugs appear.

Thanks for keeping me posted, this issue is very important for me,
unfortunatebly as I know next to nothing about packaging, I have
difficulties helping out.

Cheers,

Gaël

Well, there are simpler ways to install Mayavi2 under Linux :->.

Anyhow, the bug in hardy should now be fixed. Can you confirm this
please.

OK, I will need help from python packagers for this bug. I am not too
sure it is related to upstream problems. I don't know if these files "the
.pth" should be there or not, as I don't know how the python packages are
installed.
