py27-mayavi @4.2.0 doesn't work with ipython

[mmpagani (Marco Pagani)]

Hello, today I did a clean installation of py27-mayavi @4.2.0 on my Mac. I'm running OSX 10.8.5 with macports 2.2.0.

Some of the ports I'm using are:

py27-ipython @1.1.0 (python)
vtk5 @5.10.1 (graphics, devel)

During the installation everything worked fine but when I run the following

ipython
from mayavi import mlab
mlab.test_points3d()

I get the following error:

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Resource id in failed request:  0xb60ca360
  Serial number of failed request:  7
  Current serial number in output stream:  9

I searched the web for similar problems but I could not find useful information. Any hint on how to solve this problem will be highly appreciated. Thank you.

In the future, please fill in the Port field, Cc the port maintainers (port info --maintainers py27-mayavi), and do not set the Priority field.

It works for me. Variants can make a big difference in successful operation for these. I have:

$ port installed vtk5 py27-pyface py27-mayavi py27-ipython
The following ports are currently installed:
  py27-ipython @1.1.0_0+notebook+parallel+pyqt4+scientific (active)
  py27-mayavi @4.2.0_0 (active)
  py27-pyface @4.2.0_0+pyqt4 (active)
  vtk5 @5.10.1_0+python27 (active)

You need +python27 for vtk5 and +pyqt4 for both py27-pyface and py27-ipython.

Also note, you will likely need to do "export QT_API=pyqt" before running ipython (not for your current bug, but it resolves the "ValueError: API 'QString' has already been set to version 1" that you may get after you set the variants correctly).

Thank you for the very precise suggestions. I installed all the packages as suggested. While running the some tests I encountered a problem similar to the one described here ​http://trac.macports.org/ticket/37355 which I solved following the instructions provided. Now everything is working fine. Thanks again. Marco
