mlab.text fails
Locked

Hi, I found that mlab.text becomes unusable after upgrade to 4.2. Is it a known problem? Thanks! The report is also available at: https://github.com/enthought/mayavi/issues/35 from mayavi import mlab cause an error in MayaVi 4.2. (The code ran well before) The error is pasted. Is it a bug? /local_data/chenxing/capture/2012_06_05/ in () /usr/lib/python2.7/site-packages/mayavi/tools/pipe_base.py in the_function(*args, **kwargs) /usr/lib/python2.7/site-packages/mayavi/tools/decorations.py in init(self, x, y, text, **kwargs) /usr/lib/python2.7/site-packages/mayavi/tools/pipebase.py in __init(self, parent, **kwargs) /usr/lib/python2.7/site-packages/traits/trait_types.pyc in create_default_value(self, *args, **kw) /usr/lib/python2.7/site-packages/mayavi/core/module.py in init(self, **traits) ---> 58 self.setuppipeline() /usr/lib/python2.7/site-packages/mayavi/modules/text.py in setup_pipeline(self) /usr/lib/python2.7/site-packages/traits/has_traits.pyc in trait_set(self, trait_change_notify, **traits) TraitError: Cannot set the undefined 'scaled_text' attribute of a 'TextActor' object.

Could somebody please give some ideas on this? I've been stuck here for nearly a month. mlab.text() seems to be a very basic function, but is really useful to annotate figures. The bug is also very easy to reproduce, just do this in MayaVi:
from mayavi import mlab mlab.text(0.1, 0.1, "test") Thanks! CHEN, Xing / 陈醒 On Tue, Jul 3, 2012 at 9:19 PM, CHEN Xing <[hidden email]> wrote:

Hi Xing, I'm sorry that you've been having this trouble. Just to let you know, the two strongest mayavi experts, Prabhu and Gael, both have limited availability right now. If you don't get a response sooner, please feel free to ping again in a week or two.

How did you upgrade Mayavi? Are you using EPD?

You can retrieve it using:: from tvtk.api import tvtk v = tvtk.Version() print v.vtk_version Also, to help me fix the problem, can you give me the output of: a = tvtk.TextActor() a.print_traits() Thanks, Gaël _______________________________________________ Enthought-Dev mailing list [hidden email] https://mail.enthought.com/mailman/listinfo/enthought-dev |

Thank you very much for the update.
I'm a Linux user, and I updated Mayavi via Archlinux's AUR system. I believe I updated vtk before updating Mayavi. The version of VTK is 5.10.0. The version of Mayavi is 4.2.0 (which is the latest tagged version on github). Traits of a tvtk.TextActor(), there is a scaled_text_property, but no scaled_text_property. a.scaled_text="adsfsdf" will raise a similar error: Traceback (most recent call last): File "<stdin>", line 1, in <module> traits.trait_errors.TraitError: Cannot set the undefined 'scaled_text' attribute of a 'TextActor' object. Hope that helps.

The text won't show up even if I plot something later. This wasn't a problem for previous mayavi. Besides, the document on http://docs.enthought.com/mayavi/mayavi/mlab.html has a tiny bug, the command line to start ipython2 should be:
ipython2 --gui=wx two dashes are required for the latest ipython. Also, it will be nice to see Mayavi working with VTK 5.10 :)

OK, will fix. > Also, it will be nice to see Mayavi working with VTK 5.10 :) Agreed. I am just unsure how to find time to deal with this on top of my day work and a few other open source projects. Some people have been giving me some helping hand.

You're right. I was using a work around, calling mlab.plot3d(0, 0, 0) first to make mlab.text work. The same trick still works. Thank you for the help and good luck with your work! CHEN, Xing / 陈醒 On Mon, Jul 9, 2012 at 2:39 PM, Gael Varoquaux <[hidden email]> wrote:

I can confirm that mlab.text() doesn't work with VTK 5.10.
The problem is the version comparison. Specifically, the code converts the first 3 characters of the version string to float and then does a comparison "VTK_VER > 5.1", which is False while it should be true. In my opinion, using floats for version number is a bit crude and prone to breaking (e.g. we have "float('5.8') > float('5.10')"). A possible solution for this problem is in this branch: https://github.com/mluessi/mayavi/tree/vtk510_version On Mon, Jul 9, 2012 at 5:39 PM, Gael Varoquaux <[hidden email]> wrote: > On Mon, Jul 09, 2012 at 02:32:22PM -0700, CHEN Xing wrote: >> Thank you.

If you are reading this, thanks :) I tried running the tests and there are definitely some tests that fail. Most notably there is a "double free or corruption" which causes Python to abort when testing deep-copying the visualization (not sure where yet). I can continue looking into making Mayavi work with VTK 5.10 _______________________________________________ Enthought-Dev mailing list [hidden email] https://mail.enthought.com/mailman/listinfo/enthought-dev |
