I had a similar issue some days ago and Simon suggested to download a recently built wheel from github:

(you need to be logged in to github)

download the appropriate file and run
pip install <FILENAME>
locally.
Or
python -m pip install <FILENAME>

Solved the issue for me on MacOS.

Simon might correct me if I am writing bogus here.

Cheers
Nils

Hello,

I am new to ITK and RTK and I’m trying to use the itk-rtk python package. I set up a new environment with python 3.7 (with Conda) on Windows 10 and ran:

Pip install itk-rtk

I could import both packages, but I got the following error when I ran the example FirstReconstruction.py:

‘’
Traceback (most recent call last):
  File "D:\Program files\RTK-master\examples\FirstReconstruction\FirstReconstruction.py", line 14, in <module>
    geometry = rtk.ThreeDCircularProjectionGeometry.New()

    from . import _ITKPyBasePython
ImportError: attempted relative import with no known parent package
‘’

Does anyone know how to solve this issue?

Thanks

Sincerely,
