VTK warnings when modifying pipeline about mayavi HOT 13 OPEN

I tried a few things and found another workaround.

This will print the error messages:
plt = mlab.points3d(x, y, z)

But if you set the forth parameter ("scalars") the error messages are gone.
This works fine for me:
plt = mlab.points3d(x, y, z, np.ones_like(x))

The size of the glyphs can be adjusted by using the keywords 'scale_mode' and 'scale_factor'.

I'd love to have a fix or workaround for this. I'm using mayavi in a demo coming up and the error messages are a big detractor from the beauty of the demo.

I am also looking for a resolution or workaround for this.

Exactly the same problem, has someone found a workaround ?

The pipeline code in Mayavi needs to be rewritten to use the new VTK
pipeline design. I suspect that there is a few days work, maybe a week.
Given Prabhu's workload and mine's it is a bit hard to find that time.
That's why nothing is happening.

+1 for a fix for this issue.

Temporary workaround, redirect error messages to a log file:

import vtk
output=vtk.vtkFileOutputWindow()
output.SetFileName("log.txt")
vtk.vtkOutputWindow().SetInstance(output)

Confirmed with current Mayavi.

@GaelVaroquaux, @prabhuramachandran: could either of you provide a brief explanation of the underlying cause? I'm a bit lost in the VTK details.

I agree with solarjoe's solution. There might be something wrong with the auto scalars.
