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.

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?

I seem to remember the modification is very small, but I can't find it in the svn history. We'll see if I can find it.

OK, thanks. I am browsing through Trac history to see if I can isolate the change that fixed that, but the problem is that it is quite old, we'll see.

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.

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.
