Excuse me,I met the same problem with yours that some confidence value are more than 1.0. Have you solved it? If you have solved the problem,could you tell me how you solved it?

I experienced the same, it looks it happens when you have duplicate items in a subset.

I also had this problem; I recommend using chonyy's implementation, mlextend is too slow and memory hungry: https://github.com/chonyy/fpgrowth_py
