It seems there is no mayavi for Python 3.6 yet. See in (about 21 days ago) from prabhuramachandran himself.

BTW 'conda install mayavi' answers wirh:

UnsatisfiableError: The following specifications were found to be in conflict:
  - mayavi
  - python 3.6*
Use "conda info <package>" to see the dependencies for each package.

Hi Gary,

What happens, if you do not use the full path to 'conda', i.e. you do just:

`$ conda install mayavi`

Or - is 'conda' on your PATH?

Anyway, this looks like a problem of your anaconda installation - try asking there about your issue.

I am still trying to get a clean installation of sfepy. I am still
vtk and pysparce libraries. I need to get components that are compatible
with an amd-64, python3.x system. Any help with finding these packages
help with their installation will be sincerely appreciated.

"conda install mayavi" should install VTK for you - did you try that?

I have also found a conda package of pysparse, but it seems Python 2.7
