run simpleMontage.py get error ITK ERROR: Object factory failed to instantiate class itk::RealToHalfHermitianForwardFFTImageFilter on windows 10 #214

@tbirdso Could this be related to FFT refactoring? |
|
@dzenanz Sounds possible. I will work to reproduce on my end. |

Hi @zhusihan-python , I am having difficulty in reproducing the error that you describe. The A couple of questions to help us investigate:
I have identified a small error later in |
|
@tbirdso hi sir i build itk by myself, and i set ITK_BUILD_DEFAULT_MODULES ON, you can see that on the itk configure picture i upload i can't reproduce the error use the ITKMontage Python release from PyPI, i try to reinstall itk itk-montage from pypi, then tried the MNML_5_500x_101 files, it get another error like this: itk.TileMergeImageFilter is not wrapped for input type one of my environment is windows 10, python 3.10.10, i remove itk i build and reinstall itk itk-montage from pypi, SimpleMontage.py is the same as in this repo |
|
it works fine on linux |
|
Hi @zhusihan-python , thank you for the detailed description. The Windows error you described in |
thank you for the help, it works perfect on windows now in montage 0.7.3 the rgb image support should be like this |
Great, glad to hear it. I'll leave this issue open for now in case someone has bandwidth to investigate the C++ object factory instantiation failure. It sounds like using the Python distribution is a sufficient workaround for now. |

I'm posting here for posterity's sake. There were not a lot hits with the exact issue. There was also a forum post on the official ITK forum, but I've decided to post here to make it easier to reference across the github ecosystem. I had the exact same issue using RTK with this: and I also found that the python code did work, though migrating to python was not a viable option for us. I tracked down the issue to our conan build of ITK. Once I got that, I found that we were never registering the factories. I suspected issues with the static variables and this discussion confirmed my suspicions InsightSoftwareConsortium/ITK#2864 and explains why it works in python but not in our C++ code. Finally, the fix, there are 2 possible fixes:
# assuming that you are not using conan.

hi, i build the lastest verion itk 5.3.0 and itk montage 0.8.1 on windows 10 python 3.10.10
run examples/simpleMontage.py get error like below
itk cmake configure
itk montage configure
expectation: itk 5.3.0 and itk montage 0.8.1 run simpleMontage successfully, get a stitched image
