title: WEKA FP-growth association rules not finding rules
body: <p>For a report I have to find association rules of a data set of transactions. I downloaded this data set:
  <a href="http://archive.ics.uci.edu/ml/datasets/online+retail" rel="nofollow noreferrer">http://archive.ics.uci.edu/ml/datasets/online+retail</a></p>
  
  <p>Then I deleted some columns, converted to nominal values and normalized and then </p>
  
  <p>I got this: <a href="https://ufile.io/gz3do" rel="nofollow noreferrer">https://ufile.io/gz3do</a></p>
  
  <p>So I thought I had a data set with transactions on which I could use FP-growth and Apriori but I'm not getting any rules.</p>
  
  <p>It just tells me: No rules found!</p>
  
  <p>Can someone please explain to me if and what I'm doing wrong?</p>
