Problems viewing results
Hi,
I have the Enthought Canopy Python distribution and am new to using SfePy. I was trying to work through the examples and had a problem with viewing the results. The package manager in Canopy already has SfePy Version 2014.4 Build 6. Whenever I try to use the Viewer to look at results, I get:
ERROR:mayavi.core.common:Exception Traceback (most recent call last): File "/Users/dennis/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/mayavi/core/source.py", line 216, in _handle_children obj.start() File "/Users/dennis/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/mayavi/core/filter.py", line 108, in start self.update_pipeline() File "/Users/dennis/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/mayavi/filters/set_active_attribute.py", line 133, in update_pipeline self._update() File "/Users/dennis/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/mayavi/filters/set_active_attribute.py", line 149, in _update input.update() AttributeError: 'AlgorithmOutput' object has no attribute 'update'
I have no idea what the problem is. It happens on my Mac (running Yosemite) and also my Windows 7 machine.
I would greatly appreciate any help with this.
Thanks.

Hi,
it looks like a problem in your mayavi installation (or a newer mayavi version than sfepy currently supports). Does mayavi2 command runs by itself? Also, did you shorten a bit the traceback? This does not give any hint which Viewer part is causing that.
Thanks for the report, r.

The mayavi2 command runs by itself just fine.
The version is 4.4 Build 4

Thanks, we will check it as soon as we get to installing the same mayavi version. (Temporary workaround: try 4.1, where the post-processing works.)

I tried mayavi 4.2 and that works. Enthought's package manager makes it pretty easy to go back and forth between the current (4.4) and (4.2) so it's a good workaround for the moment.
