installing Mayavi with pip - no module named vtk

Question

I want to use Mayavi.

Situation

• I use a MacBook Air, with OSX 10.7.3.
• I use Python 2.7.2
• I have virtualenv installed.

Answer 1

I had the same problem when installing mayavi with python installed in pyenv, and I solved this problem by copy directory to /home/myname/.pyenv/versions/2.7.12/lib/python2.7/site-packages, below is my method:

1. install vtk and python-vtk

   sudo apt-get install vtk6
   sudo apt-get install python-vtk
   

2. try python -c "import vtk", if failed again, go to step 3

3. the import error may caused by the loss of vtk package folder in your current python, so we should find the vtk folder and copy to your current python(most possible the python in pyenv shims directory)'s directory .

   the path of the vtk folder in my ubuntu is

   /usr/lib/python2.7/dist-packages/vtk
   

   just copy the vtk folder to your current python's /site-packages, e.g.

   cp -r /usr/lib/python2.7/dist-packages/vtk /home/myname/pyenv/versions/2.7.12/lib/python2.7/site-packages
   

4. try python -c "import vtk" again.

5. if no import error, just do

   pip install mayavi
