I’m trying to download Radiomics but I ran into this error. Can anyone explain to me how I can solve this?
Thank you in advance

I can not explain your error messages, however you could just install the SlicerRadiomics extension and run it on your segmentations:

so are you advising me to install 3D slicer first and then pyradiomics? But won’t it give me the same problem? I downloaded visual 2022, is it correct or superfluous?

I downloaded 3D Slicer and I downloaded the Pyradiomics extension.
But I’d still like to understand why he didn’t let me download it via pip. Also why shouldn’t the wheels be installed automatically by python?
