I executed

./libFM -task r -top_k 10 -iter 5 -out y_pred.txt -method bpr -train train.libsvm -test test.libsvm -dim '1,1,8' -relation feature_t,label_t

and I set train.libsvm and test.libsvm to null text files.

The output information is :

Loading train...

I don't understand what it means. Dose it indicate that I have a 0 in the wrong place? But where?

It was because my label_t.x was not in libsvm format......And now it has been solved.
