When I run scenario runner on ubuntu 16.04 with python3 I get this or similar error with all scenarios:
Traceback (most recent call last):

Hi,
which version of py_trees do you use? We support py_trees 0.8.x. It seems things have changed with version 1.x (there it is SuccessOnOne).

See also Issue #24

Thank you. 0.8.3 works!

@rguptatx hello,Have you created a successful scenario by referring to the example of the official scenario creation?(https://carla-scenariorunner.readthedocs.io/en/latest/creating_new_scenario.html)
