[ITK-users] ITK Python wrapping

[D'Isidoro Fabio]

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.

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:


-        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 (no module named _ITKPyBasePython ... something related to SWIG, that I don't have). Do I need to install Swig? (In a similar question in the iTK Wiki page the answer was: you will need the ITKv4 wrapping to use this example ... ?)


-        Seemingly, in the new virtual env I try to run "python ImageRegistration3.py BrainProtonDensitySliceBorder20.png BrainProtonDensitySliceShifted13x17y.png output_image" in attachment (modified from the Examples folder with proper inputs), which starts with "import itk ; fixedImageReader  = itkImageFileReaderF2_New()" I get the error "name itkImageFileReaderF2_New is not defined".


Lacking of a guide, I actually have no clue about how to use Python wrappers in general. Is there any guide that I could follow?

Useful info:

I have successfully built ITK with Cmake with the ITK-WRAP-PYTHON option. The build had some failures related to the CastXML tool... could this be a problem?

I configured a new Python virtual environment within my ITK build directory.

I copied/pasted the file /path/to/myITK_wrapped/Wrapping/Generators/Python/Debug/WrapITK.pth into wrap_itk_venv/Lib/site-packages. Is that correct to generate a symbolic link in Windows?

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

Thank you for your help.
