mayavi crashes Jupyter notebook

Has anyone been able to use conda to install mayavi. I have tried everything under the sun. The farthest that I have gotten is being able to successfully run:
```
from mayavi import mlab
mlab.init_notebook()
```
but it crash when I run:
```
s = mlab.test_plot3d()
s
```
I also tried running other applications that says that I have no UI toolkit even though I have installed pyqt and pyside
```
ImportError: Could not import backend for traitsui. Make sure you
have a suitable UI toolkit like PyQt/PySide or wxPython
installed.
```
I'm sorry that I can't provide my environment because now my kernel just crashes when I try to import mlab from mayavi. Has anyone gotten this to work with conda or am I just going to have to pip install everything?
