Public bug reported:
This is not a true bug but there has been a change of syntax (starting with
ubuntu 12.04)
which was not evident for me (and I could not find the full correct syntax
anywhere else in the web).
Therefore I decided to put it here, hoping it would save others some time...
on previous ubuntu versions I used to use mayavi's module "mlab" within
an ipython + pylab session, using the following command:
ipython -wthread -pylab
After updating to ubuntu 12.04 this no longer works.
Searching the web I found that pylab should be called using --pylab (double
dash instead of a single one)
and -wthread should be replaced with --gui=wx (again, a double dash is
required).
trying:
ipython --pylab --gui=wx
(as well as interchanging the order of the arguments) failed.
First due to python-gtkwx problem which I reported (and some solution is
proposed) here:
https://bugs.launchpad.net/ubuntu/+source/wxwidgets2.8/+bug/998716
Next there was a problem with the behaviour of the mayavi window, invoked in
ipython using (for example):
from mayavi import mlab
mlab.points3d(0,0,0,color=(1,0,0))
The plot was unresponsive.
To make it interactive I had to run:
mlab.show()
which turned the ipython session unresponsive till the mayavi window was
closed.
Finally, I started the session using:
ipython --gui=wx --pylab=wx
(so far, works also when omitting "--gui=wx")
For those who would like to run in the "notebook" flavour, inlining the
pylab plots:
ipython notebook --gui=wx --pylab inline
works nicely so far...
I hope this is useful for other users as well.
