Thank you for replying. I'm pretty sure that I haven't changed anything in the example script. What I just did is copy and paste and run it.
geometry was defined like this geometry = rtk.ThreeDCircularProjectionGeometry.New() and could you explain me how to translate(?) does documents into pythonic way? (I don't know much about Clang) for example, in the link you gave me it says *rtk::FDKConeBeamReconstructionFilter< TInputImage, TOutputImage, TFFTPrecision > Class Template Reference * I empirically know that in python I have to type something like *rtk.FDKConeBeamReconstructionFilter[InputImage, OutputImage, FFTPrecision]* Am I right?? 2020년 4월 21일 (화) 오후 4:58, Aurélien Coussat < [email protected]>님이 작성: > Hi, > > Your first error is really strange.
