title: Installing VTK for Python
body: <p>I'm trying to install VTK module for python, I am however unsuccesful in doing so. I have downloaded a VTK tar-file, but I'm unable to extract it. I'm capable of extracting other tar-files, so there must be something specific with this file I suppose.</p>
  
  <p>This is my error:</p>
  
  <p>gzip: stdin: invalid compressed data--format violated
  tar: Child returned status 1
  tar: Error is not recoverable: exiting now</p>
  
  <p>I hope somebody can help me with this.</p>
