Error in evaluation of a strategy

Hello,

I am writing to inform you that unfortunately there is a problem when a scenario will be evaluated after training. In other words, when the below function will be called:

strategy.eval(scenario.test_stream)

This error will be shown:

AttributeError: 'RLScenario' object has no attribute 'test_stream'

Is there any update or solution for this issue?

Thanks in advance
