This error happens whenever I try to add Lantern or Timing Gear type

I'm getting the same error. Is this workbench still supported?

I tested all commands on latest FreeCAD weekly and all it's fine.

It could be that another WB included an old version of scipy when it doesn't had that attribute? Happened to me once.

Also fails for me in Timing Gear with the same error.

Please add: from scipy import optimize to the import section of timinggear_t.py to fix. No other issues apart from this.

Context: freecad-daily (0.22.0dev) under Linux mint (Ubuntu 22.04), python 3.10.12 and scipy 1.8.0

should be fixed now.
