Not deterministic with random_state=0 #1291

Closed steffen-limmer closed 9 months ago

steffen-limmer commented 1 year ago

TPOT is not deterministic with random_state=0. The reason is that in the _compile_to_sklearn function it is checked whether random_state is set with the statement "if self.random_state". This evaluates to False for random_state=0 and should be replaced with "if self.random_state is not None".
