<p class="MsoNormal">I am a newbie, trying to use ITK with Python wrapping on Windows 7. Using the short ITKSoftwareGuide, but could not find a comprehensive guide to use Python wrappers for dummies.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My problem is: I can’t make the Python wrapping work. I can import itk with no errors when running Python in the new virtual environment configured inside my ITK build directory. But:<o:p></o:p></p>

</span></span><![endif]>As in this example (http://www.vtk.org/Wiki/ITK/Release_4/Wrapping/Examples) , I get no error for “PixelType = itk.UC” but when trying “ImageType = itk.Image[ImageType, 2]” I get the error1 in attachment (<b>no module named _ITKPyBasePython</b>
… something related to SWIG, that I don’t have). <b>Do I need to install Swig</b>? (In a similar question in the iTK Wiki page the answer was: you will need the ITKv4 wrapping to use this example … ?)

which starts with “import itk ; fixedImageReader = itkImageFileReaderF2_New()” I get the error “name itkImageFileReaderF2_New is not defined”.<o:p></o:p></p>
<p class="MsoListParagraph"><o:p> </o:p></p>
<p class="MsoNormal">Lacking of a guide, I actually have no clue about how to use Python wrappers in general.

<p class="MsoNormal"><u>Useful info:<o:p></o:p></u></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have successfully built ITK with Cmake with the ITK-WRAP-PYTHON option. The build had some failures related to the CastXML tool…
<b>could this be a problem</b>?<o:p></o:p></p>

<p class="MsoNormal">I configured a new Python virtual environment within my ITK build directory.<o:p></o:p></p>

<p class="MsoNormal">I copied/pasted the file /path/to/myITK_wrapped/Wrapping/Generators/Python/<b>Debug</b>/WrapITK.pth into wrap_itk_venv/Lib/site-packages.
<b>Is that correct to generate a symbolic link in Windows</b>?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also added path/to/myITK_wrapped, path/to/myITK_wrapped/bin and path/to/myITK_wrapped/bin/Debug in my user env variable PATH<o:p></o:p></p>
