AttributeError: '__signature__' attribute of 'XCounter' is class-only

[adjivas]

Hello,

I try to apply the reactor readme.
I written this example, I try to use a component.
Unfortunately, I get the error AttributeError: '__signature__' attribute of 'XCounter' is class-only.

Do can you inform myself of what I forget?

This is my full traceback logs:
