[Bug 776078] Re: Can no longer use mlab
A quick followup: about the 'threads' issue, this seems to be a bug related to ipython (see https://bugs.launchpad.net/bugs/777420 and https://github.com/ipython/ipython/issues/185). This is fixed by upgrading to ipython 0.10.2, which is available from ubuntu oneiric (no additional dependency compared to natty): wget http://launchpadlibrarian.net/70857487/ipython_0.10.2-1_all.deb sudo dpkg -i ipython_0.10.2-1_all.deb After installing this version, I can use ipython -pylab with the GTKAgg backend working, and I also get a working console&GUI using mlab with "ipython -whread". Hopefully this version of ipython can be pushed to natty as well. => go to https://bugs.launchpad.net/bugs/777420 if you wish to follow up on this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776078 Title: Can no longer use mlab -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Tested the proposed package and the import problem is fixed. As vincefn has noted, running with ipython -wthread no longer has interactive update of the plot area. One needs to run mlab.show() to have that window updated. The immediate issue of mayavi2 broken is fixed.

Ah, right - the mlab window popped open without using show(), so I did not try that. If I use mlab.show() after, e.g., mlab.test_contour3d(), then the interaction is OK !

Hi, I have a freshly updated natty system. I can confirm the bug. I can also confirm that updating to python-enthoughtbase 3.0.6 fixes the issue when importing mlab, but then the event loop seems stuck (can't interact with the mlab window, using ipython -wthread or simply python).

I tried installing python-enthoughtbase_3.1.0-1_all.deb, but there's a dependency with the python version (<<2.7 ?), and I'm not sure I can quickly work around.

mayavi2 and enthought-base are developped and released together. It's a bug of the Ubuntu distribution (and maybe Debian) of not upgrading them together.

[Bug 776078] Re: Can no longer use mlab
There's another option which I'd like to at least see mentioned, which is patching mayavi2 to work with the older version of python- enthoughtbase. My concern is that the newer version of python- enthoughtbase might break the API for other reverse dependencies. That said, the list of rdepends is short, so it might be better/easier to backport 3.0.6 and test the other reverse dependencies heavily. Either path, heavy testing of rdepends, or patching mayavi2 to work w/ the older python-enthoughtbase, should be acceptable for SRU. On a side note, its confusing why those versions aren't translated into the Debian packaging. That would at least make it more likely that this doesn't happen again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776078 Title: Can no longer use mlab -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 776078] Re: Can no longer use mlab
The problem most probably comes from the fact that python-enthoughtbase has not been upgraded while mayavi2 has. Mayavi 3.4.0, as shipped in natty, depends on python-enthoughtbase 3.0.6, as detailed in the dependency list: https://github.com/enthought/mayavi/blob/3.4.0/setup_data.py python-enthoughtbase 3.0.5 is shipped in natty: http://packages.ubuntu.com/natty/python-enthoughtbase The easiest fix is probably to backport python-enthoughtbase.
