I have a problem. I compiled SlicerCustomAppTemplate, installed SimpleITK in it’s build-in python, and it crashed when I run “import SimpleITK” in python script.
My environment is Ubuntu22.04. I didn’t open the Slicer_USE_SimpleITK option when compile Slicer, but install SimpleITK by pip, because I find that there are many things to install when open the Slicer_USE_SimpleITK, is it matter?
If you want to use SimpleITK in Slicer then you need to enable Slicer_USE_SimpleITK. If you install some ABI incompatible SimpleITK binaries from PyPI then Slicer will crash.
A special mechanism was implemented for ITK-Python that allows standalone installation from wheels (Slicer’s ITK does not clash with ITK-Python’s ITK), but as far as I know, this mechanism has not been implemented in SimpleITK. If you don’t want to build SimpleITK but you want to use ITK from Python then you can use ITK-Python.
Thank you! I’m trying to compile with Slicer_USE_SimpleITK is ON, and still encountering some difficulties. Perhaps rewrite this part of code with ITK-Python is a good idear.
If you already installed SimpleITK using pip then you may need to uninstall it, as it may interfere with the one that Slicer builds. But switching to ITK-Python could be a good solution, too.
