Probably too late, just wanted to confirm that in Windows in OQ 3.24.1 after "pip install jupyter" in the OQ environment I can do e.g.
from openquake.hmtk.faults.fault_geometries import (
SimpleFaultGeometry,
ComplexFaultGeometry,
)
without a problem in that jupyter in OQ environment, probably OQ environment is not loaded behind your jupyter...
