py27-mayavi: build ok, but unusable with error `ImportError: No module named cocoa_render_window`

[nilstec_inc@…]

I installed mayavi for python 2.7 using the following ports

vtk5 @5.10.1_0+python27+qt4_mac
py27-mayavi @4.1.0_0
py27-pyqt4 @4.9.6_1

Install went fine without problems. But when I try using it, doing

ipython
from mayavi import mlab
mlab.test_points3d()

I get the error message ImportError: No module named cocoa_render_window. I'll supply port installed and the full error message from python.

I am not sure why you are receiving this error. The relevant ports appear to be installed and with the correct variants (+qt4_mac is not needed for VT5, but it should not hurt either). Just to make sure it is not a problem with ipython, do you get the same error from python?

[bash terminal] & python2.7
>>> from mayavi import mlab
>>> mlab.test_points3d()

Unfortunately I get the same error using only python.

Error output of pure python

OK, that rules out some problem with ipython. Can you check the contents of

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tvtk/tvtk_classes.zip

to see if it contains cocoa_render_window.py? If not, you can try rebuilding py27-mayavi.

I can not find cocoa_render_window.py in that file. Ill supply the file contents, and try rebuilding py27-mayavi. Thank you very much!

contents of tvtk_classes.zip found in /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tvtk

[nilstec_inc@…]

I did

sudo port uninstall py-mayavi
sudo port uninstall py27-mayavi
sudo port install py27-mayavi

and now it works! The above given file now contains cocoa_render_window.py. Thank you very much for your time!

Glad to hear it!
