Hi, I have tried to use your stratified sampling code on python 3, but it really doesn't work, it doesn't resample, can you help?

@ThabangDLebese Can you post an example of what is your input and the output or error you are getting? This can help me to know what to debug or how to help you

OUTPUT
total number of customers: 4760
number of actual churners: 243
total number of non-churners needed to obtain 20% of churners: 972.0
the new sample will be made of 1215.0. That is 25.525210084033613% of initial dataset
==> resampling ...
Enter posRate higher than the initial rate
Done sampling
positive: 0
negative: 0
final size: 0

So there is no sampling at all :(
