[Paraview] Importing paraview.simple in external python environment

[livia.barazzetti at istb.unibe.ch]

Hi,
I am trying to use paraview python scripting from an external python installation (enthought canopy).  I am trying this because I could not import successfully scipy in pvpython (namely scipy.signal)  .
I created a file called paraview.pth in "C:\Users\lb\AppData\Local\Enthought\Canopy\User\Lib\site-packages". The content of the file is the following:

C:\\Program Files (x86)\\ParaView 4.0.1\\lib\\paraview-4.0\\site-packages
C:\\Program Files (x86)\\ParaView 4.0.1\\lib\\paraview-4.0
C:\\Program Files (x86)\\ParaView 4.0.1\\bin
C:\\Program Files (x86)\\ParaView 4.0.1\\bin\\python27.zip
C:\\Program Files (x86)\\ParaView 4.0.1\\bin\\DLLs
C:\\Program Files (x86)\\ParaView 4.0.1\\bin\\lib
C:\\Program Files (x86)\\ParaView 4.0.1\\bin\\lib\\plat-win
C:\\Program Files (x86)\\ParaView 4.0.1\\bin\\lib\\lib-tk
C:\\Program Files (x86)\\ParaView 4.0.1\\bin
C:\\Program Files (x86)\\ParaView 4.0.1\\bin\\lib\\site-packages

(I copied the paths from the command sys.path in pvpython)

The only relevant difference I can see between the two installation is that Canopy Python version is '2.7.6 | 64-bit | (default, Apr 11 2014, 20:31:44) [MSC v.1500 64 bit (AMD64)]', while in  pvpython  the version is '2.7.3 (default, Jun 16 2013, 20:21:46) [MSC v.1500 64 bit (AMD64)]'

When  I try to run "import paraview.simple" in canopy I have the following error:
Error: Could not import vtkCommonComputationalGeometryPython

ImportError                               Traceback (most recent call last)

----> 7 from vtkCommonCorePython import *
      8 from vtkCommonDataModelPython import *
      9 from vtkCommonExecutionModelPython import *

ImportError: DLL load failed: The specified module could not be found.

I searched and vtkCommonComputationalGeometryPython.pyd is present in "C:\Program Files (x86)\ParaView 4.0.1\lib\paraview-4.0"  and vtkCommonComputationalGeometryPython27D-pv4.0  in C:\Program Files (x86)\ParaView 4.0.1\bin (then both folder are already in paraview.pth). I checked with visual studio "dumpbin /headers" that vtkCommonComputationalGeometryPython.pyd is 64 bit.

I am using Paraview 4.0 (binaries downloaded from the website) on Windows 7 64 bit.
Any suggestion?
