My extension MRUSLandmarking stopped working when Slicer 5 was introduced.
It works when I add it ‘locally’ through Extension Wizard → Select Extension, however, when it is installed through the Extension Manager it cannot be loaded.
The error comes from an import statement from the beginning of the main file, where I import a .py file where I have additional code:
Traceback (most recent call last): File "<string>", line 1, in <module> File "/Applications/Slicer-stable.app/Contents/lib/Python/lib/python3.9/imp.py", line 169, in load_source module = _exec(spec, sys.modules[name]) File "<frozen importlib._bootstrap>", line 613, in _exec File "<frozen importlib._bootstrap_external>", line 850, in exec_module File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed File "/Applications/Slicer-stable.app/Contents/Extensions-30893/MRUSLandmarking/lib/Slicer-5.0/qt-scripted-modules/MRUSLandmarking.py", line 12, in <module> import Resources.utils ModuleNotFoundError: No module named 'Resources.utils'
I’m confused why this error only happens through the extension manager.
I couldn’t find any guidelines on how to correctly do those imports in Slicer extensions, and I came up with the current way through trial and error.
What is the correct way of doing this?
