Ambiguity threshold in 2-stage Fallback policy doesn't work

Hi,

Although I set an ambiguity threshold of 0.1, the fallback action is not triggered even if the first action has 0.32 and the second one 0.25. Why could it be?

Thank you, Tiziano

Didn’t you face any issue while using ambiguity_threshold in TwoStageFallbackPolicy? I am facing the issue TypeError: init() got an unexpected keyword argument ‘ambiguity_threshold’

Nop, I’m not getting that error. But still, doesn’t seem to work as expected
