only same output

[yunseongcho]

I'm trying to learn ffm model by this dataset

This dataset has approximately 10 million instance in size.
and the code is below

import xlearn as xl
ffm_model = xl.create_ffm()
ffm_model.setTrain("./train.txt")
param = {'task':'reg', 'lr':0.2, 'lambda':0, 'metric':'rmse'}

ffm_model.setTXTModel('./model.txt')
ffm_model.fit(param, "./model.out")
ffm_model.setTest("./test.txt")
ffm_model.predict("./model.out", "./output.txt")

This is a variation of the code example in xlearn documentation.

But always outputs are same value.
I tried to change parameter, and tried to change a little in dataset.
but the problem isn't solved.. help me please..
and I can't speak Chinese plz comments in english..

혹시 아직 해결 못하셨다면 제가 최근에 올린 이슈를 참고해 주시기 바랍니다.
제 경우에는 전처리 후 라벨 자리에 있어야할 데이터가 잘못될 경우에 저런 증상이 나오더라구요
