I have a question. In the filters, such as ReverseWordRatioBucket.py, if self.scores is [], the program will wrong,

self.scores It will be assigned in Tu function. How can I fix the problem?

Hello,

Can you please give me more information to recreate the error?
The "self.scores" should not be empty in that step.
In the initialize() method, is "self.num_of_scans" equal to 1?
