Signal 11 encountered when running 3d example

That's surprising. It sounds like this may likely be caused by trying to plot the results. If you comment out the plot commands in the 3D case, does it run?

Hi capaulson, yes runs fine if I comment out the plot. I'm running ubuntu not windows is this likely to cause issues?

[capaulson]

In a python terminal, can you run:
import mayavi.mlab as mlab
Please post the results.

import mayavi.mlab as mlab

Nothing else output, Cheers Darren

just noticed that after posting this didn't format as expected but to clarify no errors or other text was outputted to the console

Can you try running this:

# Create the data.
from numpy import pi, sin, cos, mgrid
dphi, dtheta = pi/250.0, pi/250.0
[phi,theta] = mgrid[0:pi+dphi*1.5:dphi,0:2*pi+dtheta*1.5:dtheta]
m0 = 4; m1 = 3; m2 = 2; m3 = 3; m4 = 6; m5 = 2; m6 = 6; m7 = 4;
r = sin(m0*phi)**m1 + cos(m2*phi)**m3 + sin(m4*theta)**m5 + cos(m6*theta)**m7
x = r*sin(phi)*cos(theta)
y = r*cos(phi)
z = r*sin(phi)*sin(theta)

# View it.
from mayavi import mlab
s = mlab.mesh(x, y, z)
mlab.show()

This is a demo from Mayavi (http://docs.enthought.com/mayavi/mayavi/mlab.html). Does it plot?

[DarrenLynch]

Hi, sorry I have been away a while. No this didn't plot, I expected it to fail at the plotting stage however if failed at the s = mlab.mesh(x, y, z) stage with error: 'Segmentation fault (core dumped)'

Right, so this sounds like an issues with your install of mayavi. It could be just an issue with the install, so you could try rebuilding/re-installing the library. It might also have something to do with virtualbox. Not sure exactly how mayavi works on a virtual box.

I'm going to close this out, as this is an issue related for another library.
