Handler Loading problem

[cmavrogiannis]

When trying to simulate, the handlers associated with motion control, sensors and actuators are not loaded, resulting in the following error log:

[18:21:37] AttributeError
[18:21:37] :
[18:21:37] 'NoneType' object has no attribute 'name'

I attach a screenshot from the 'Configure Simulation' window:

sorry for the late reply. are you still having this issue?
The basic sim does not have any sensor or actuator.
I am not very sure why the motion control handler is not loaded. But there should be an error message in the terminal window saying the reason for why the loading failed.

Same issue on the init handler. The terminal outputs like this:

raceback (most recent call last): File "/home/yzchen/CODE/task_planning/LTLmop/VerifiableRobotics-LTLMoP-b6cd72d/src/lib/configEditor.py", line 1096, in onClickConfigure dlg._handler2dialog(deepcopy(self.robot.handlers[htype])) File "/home/yzchen/CODE/task_planning/LTLmop/VerifiableRobotics-LTLMoP-b6cd72d/src/lib/configEditor.py", line 419, in _handler2dialog drawParamConfigPane(self.panel_configs, methodObj, self.proj) File "/home/yzchen/CODE/task_planning/LTLmop/VerifiableRobotics-LTLMoP-b6cd72d/src/lib/configEditor.py", line 57, in drawParamConfigPane r_names = [r.name for r in proj.rfi.regions if r.name.lower() != "boundary" and not r.isObstacle] AttributeError: 'NoneType' object has no attribute 'regions'

I solved this by pip install scikit-learn and also installed the other required binaries mentioned in "Other Optional Dependencies" section in the installation doc. Not sure which one is the key but it worked after I did those.
