Mayavi 4.6.2 vs 4.6.1

Dear all,
I'm having an issue between version 4.6.2 and 4.6.1.
We've develop a full application using mavai for 3D vizualisation. The user can rotate some geometry and pick specific surfaces that are replotted in an other mayavi scene in order to add some elements on it (that are repoprted in the first scene as well).
I'm using python 3.6.5, pyqt5, and some others and it worked fine with mayavi4.6.1 and vtk 8.1.0. For deployment puprose I've reported all the installation on a colleague laptop and encoutnered the VisualStudio (I'm on windows) compatibility for traits and mayavi package installation. I've solved so solution on my laptop (don't remember really how but surely by upragding VS to VS2015). Since I didn't manage to get rid of VS compatibility on my colleague laptop, I've installed mayavi and traits using wheel files. In workes fine for some geometry but some others make the application crashe. By upgrading 4.6.1 to 4.6.2 (keeping all other packages unchanged) in my laptop I also get the crashe. It comes in the following command line that correspond the identification of the picked surfaces by highlighting it in scene1 :+1:
self.highlight.mlab_source.reset(x=plane_coord[0],
y=plane_coord[1],
z=plane_coord[2],
scalars=ones_like(plane_coord[0]))
no error messages, just : Python has stop running !

Would it be possible to get a wheel file for 4.6.1 version ? or any idea on how to solve this issue ?
