Description: ITK ERROR: Object factory failed to instantiate class itk::RealToHalfHermitianForwardFFTImageFilter<class itk::Image<double,3>,class itk::Image<class std::complex<double>,3> >

The version attempted to use the RTK library, and there was no problem running the test program. I copied the example in the example and encountered this error.

After recompiling the library twices, it became normal.

I have get this error。。。。。

after recompiling what?do you use ITK5.4? i find that in ITK5.4 RTK is part of ITK,More precisely,RTK is a Module of ITK,so maybe there is no need to compile RTK,and i compiled ITK,the same error as you mentioned occurs,could you please tell me you solution,thank you!
