Segmentation fault about libffm HOT 8 CLOSED

Thanks for reporting the issue. Will fix the bug soon.

I met the same question too. The input file was generated by "svm-scale" of libsvm (thus I believe the format is correct). The input file has 30k lines, 6k columns at most.

The OS I used was Debian wheezy with g++ 4.7

Thanks.

Hi @guestwalk

I just downloaded your repository and tried to execute my file (svmlight format) through ffm-train - I get the same error. Could you please shed some light on how the issue can be negated?

Thanks,

Have you converted it to FFM format? If not please see README. Thanks.

Thanks for your reply @guestwalk . Following your suggestion I could address the issue I reported. However, now my tr_logloss and va_logloss comes out to be 'nan' for all the iterations. Could you please give me some idea of possible causes for that?

Thanks in advance,

It's hard to say. Indeed NAN sometimes happens in some data sets. (For example, NLP data sets) I think if you can mail me a tiny data set that can lead to NAN it would be easier to investigate. Thanks.
