title: Paraview : Glew could not be initialized
body: <p>I am trying to run a simple code for paraview from jupyter notebook as following: </p>
  
  <pre><code>from paraview.simple import *
  cone = Cone()
  Show(cone)
  Render()
  </code></pre>
  
  <p>But this gives me an error</p>
  
  <blockquote>
    <p>ERROR:In/home/conda/feedstock_root/build_artifacts/paraview_1532760595263/work/VTK/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx,
    line 781 vtkOSOpenGLRenderWindow (0x556661755060): GLEW could not be
    initialized.</p>

  <p>The error remains the same when I run it from a python shell. I also installed paraview using conda. I am using Python 2.7. </p>
