ModuleNotFoundError: No module named '_itkSiddonJacobsRayCastInterpolateImageFunctionPython'

[jazb83]

I am trying to change the code from ITKTwoProjectionRegistration/test/GetDRRSiddonJacobsRayTracing.cxx to python.

However, I am not sure how to import the itkSiddonJacobsRayCastInterpolateImageFunctionPython module in python.

So far, the error is coming from these lines of code :

from itk import itkSiddonJacobsRayCastInterpolateImageFunctionPython as siddon

// Create a ray casting interpolator
interpolator = siddon.itkSiddonJacobsRayCastInterpolateImageFunctionIF3D
// After I create the interpolator I can set all the values associated to it.
// I mean it is recognize by pycharm ( i.e. "interpolator." gives all the methods/atributes associated to // it"
interpolator.SetProjectionAngle(0)
interpolator.SetFocalPointToIsocenterDistance(1000) # Set source to isocenter distance in mm
interpolator.SetThreshold(0)

When I tried to execute the script , I got this error:

Traceback (most recent call last):
File "C:\ProgramData\Anaconda3\envs\PY\lib\site-packages\itk\itkSiddonJacobsRayCastInterpolateImageFunctionPython.py", line 22, in swig_import_helper
fp, pathname, description = imp.find_module('_itkSiddonJacobsRayCastInterpolateImageFunctionPython', [dirname(file)])

raise ImportError(_ERR_MSG.format(name), name=name)
ImportError: No module named '_itkSiddonJacobsRayCastInterpolateImageFunctionPython

During handling of the above exception, another exception occurred:

Dear jazb83, Did you found whats the problem for this error?

[jazb83]

No, I have not worked on it. I am using the C++ implementation and I almost finished with everything that I want to do and then I will go back to try it in Python.

If you know the answer to the problem pls share it.

Hi jazb83, did you succeed in converting to pyton? I tried to do the same but ran into the same error

[jazb83]

I didn't sorry. I used the c++ implementation.
