[sambaPython24]

When trying to run the example provided here,
I get the error

It is difficult to debug for me as the simulater.stepper function does not have any docstring that would reveal, what arguments it takes.

@sambaPython24 thanks for trying XLB. It looks like you have pip installed XLB but are using the latest examples from the repo. If you want to keep your installation please go back to this version https://github.com/Autodesk/XLB/tree/v0.2.1

Otherwise you can clone the latest repo and this example should run without errors.
